Waiting on parts. I ordered a new stator, regulator and flywheel tool.  The new coil and Casoli CDI arrived and still no visible spark. I hooked up the multimeter and with the multimeter probe attached I then had visible spark?? This leads me to think there is a bad ground somewhere but none could be found and everything is attached.  Im begining to think that this was an intermittent falt which may have been the reason my scooter wouldnt run for more then a few seconds after the previous (before bbk) engine mods.  Also since last posting, my Hoca roller spring base which was lost in the mail finally was forwarded to me and attived yesterday and has since been installed. The eBay jetting deal I scoref arrived as did tbe AU nozzles and such. Tbe bike is really close.... I hope :\

Great to hear some of the good news, like you may have a good kit on the side. The roller base is great if your spring wasn't as stiff as you wanted. I had to leave out the metal spacer that was in the clutch to begin with. It would bind and not allow full spring compression. The results weren't mind blowing, but it does help a bit.
Lemme know if that cdi does any better. Most people have told me to stick to the stock, but I don't follow instructions well, lol.
Not to try to sound like a jerk or repeat myself, did you check your plug wire alone? I said before, I had a problem I chased forever, bouncing back and forth between spark and fuel problems, just to find that the plug wire needed a trim and put back on the cap. It was wore out just enough that when wiggled it would cut out, mainly at idle or low rpms. You saying it came back intermittently makes me think of how mine did that.
Anyways, keep me updated!

Hmmm im still stumped. The stator arrived today but is a slightly larger 8 pole stator. To be honest Im not sure how a stator could even go bad. I cleaned the magnetic strips on tbe inside of the flywheel and went ahead and swapped the magnetic pickup from the new stator to the old, as tbat seems to be tbe only part that looked a little worn down. I swapped the pressed in nozzle in the carb, installed the AU nozzle, upjetted to a 103 main and 42 slow jet. Which side of the press in nozzle faces the air box side? Open cresent or closed? I have the closed facing out.  Sorry for the lack of punctuation.  The bike has tried firing several times. Ive noticed that my starter can barely rotate the engine with the plug installed and they is a kickback in the kick start. Occasionally ill get a good kick and the bike sputtesputtera bit. Does removing the flywheel affect the timing at all?  It just seems the kick and the piston arent in sink, or maybe im just frustrated??  BTW I have trimmed the coil lead. It didnt really need it but i was taking advise given.

Can you start over one time, and list what is happening?

When it started, and why? what you have done?

I never pulled out an atomizer so I would have to look to see which side is which, but logic tells me it should have the cut out facing the airbox.

Also the small trigger coil may have to be slotted to move it toward a more retarded setting. I have had to do this even on OEM replacements where the bends in the metal were not exact. It won't hurt to pull the flywheel again, and double check the key did not fall out on install.

Sure thing.  Well, I Swapped to a 72cc BBK and 19mm Dell Rep carb. Everything assembled well and I tried to fire its maiden start-up after the install, and nothing happened. After much troubleshooting and re checking, I found a no spark situation. This is odd as the scoot was firing prior to the BBK, although not running as prior to the BBK I modded the stock jug and such (as you may recall?). At that time I made the mistake of assumtion, in that I assumed I had spark. I also assumed being relativly newb to cylinder mods that I flubbed the stock stuff (even though Im very presice and detail oriented).  During this timeI also added a few other bits like new clutch springs, Hoca roller base,  and contra spring. (Not that those should affect any of my cutrent issue). So fast forward to the carb and no spark: as stated its a 19mm Dell replica. Yesterday I swapped in an AU main jet holder, and AU nozzle even though the stock pressed in nozzle is identical in every way.  Nozzle was installed closed end out which might be wrong. I up jetted to a 103 main jet (open filter/velocity stack)  and 42-43 small jet. All my lines to tbe carb are installed correctly and as noted buy you on page 1. After researching the no spark issues a couple weeks ago it  suggested that most no starts are due to a bad stator (I assume pick-up).  I ordered and recieved an 8 pole stator and regulator/rectifier slated for the super 9. It is too large to fit in the flywheel with the magnetic pickup strips still installed in tbe flywheel (not sure if they can be removed or bypassef??).  I have not changed regulators yet. Since the stator is only coiled wires and magnets, not much can go wrong so I removed the timing pickup from the stock stator and swapped the new pickup on, keeping the stock 6 pole stator which fits inside the flywheel. Everything is reassembled, all connections are checked and all looks good. I first try the electric start and it can barely rotate the engine, almost as if the battery is weak. The starter rotates the engine fine and strong with the sparkplug removed from the head. So I use the kick starter. Im kicking like a Taliban goat and not getting much. I pull the choke open and kick and the bike does a double sputter (same sound as nomal when kicking but twice as long as if trying to fire). When the bike tries firing, there is smoke coming from the exhaust which is I can assume is pretty loaded up at this point and smells very rich. There is also a kick back to the kick start and it actually stops mid kick as if the piston/crank are out of timing, or I possibly and more likely re installed the kick mechanism wrong after CVT cover mods.  The bike is obviously getting fuel but no spark and why the hell is the starter having trouble?  Long post but gives a good picture of whats going on. Any help would be great. Thanks guys.

Well the new cylinder will have more air/fuel to compress, and maybe a higher compression ratio. That will make a marginal electric starter appear bad.
I would start off with a new battery.

If it still spins over slow then a new starter...

You are most likely too rich on the pilot jet. These bikes, and kits are goofy. No two will take the same set up.
I would try a 38-40 pilot jet, and a new spark plug.
The fact that it kicks back is telling there is enough spark to fire it but too much fuel.

The re-jet should get you running, and from there we can trouble shoot the rest. I would return or sell the 8 pole stator to. It's of no use to you.
Where did you buy it?

I bought the stator on ebay.  It was like $18 so not a huge loss but I will try to return it if possible.  Is the pilot jet the very tiny one?  You really think Im getting spark? I can't visibly see the plug sparking when removed from the head.  Also wanted to ask about the carb adjustments themselves. I have not adjusted anything from the factory settings as I figure they have them set to atleast run as is... Maybe not run well but run none the less. Is that a fair assumption?  Maybe tomorrow I will turn the open end of the carb nozzle to face the airbox side, double check the small jet size and drop the main down to a 100.  I ordered 6 new NGKs the other day and they should be here tomorrow. Id really like to get this jigabo running this weekend. Anything else I can do to help the cause and get things going?

Grab that plug and feel the bite! That's my sure fire way to tell if I got spark. It's kinda addicting. I found that my pilot jet on the 19mm is only a twenty. It might be that small to compensate for the over rich needle I have in it.
I would be at wits end if i were in your position. You are a stronger man than I...

Listen to Tries. Don't be a girl (sorry BlueSin) See if it bites you. You do know the plug has to be touching the metal engine to make a spark?

The only thing to do now is wait for an assortment of jets. 20 sounds tiny but it may be what that carb needs to run.
try a 20/25/30/35/40.
The mains wont matter until you get a good pilot jet but 100 sounds like a fair place to start.
When you order jets I would also get 105/110/115/120/125 mains.

The idle mix screw is on which side of the carb? Near the engine or near the air box?

If you get addicted to sparking yourself, I don't know you, and was never here.

There was some tingle to the lead the other day but nothing that made me jump and yes I have it on metal. Ill play with the jets today and see. The assortment I got was a mixed bag from a dirtbike racer who was finished with racing. $9 shipped on eBay so I wasnt too picky. I was thinking and I do remember the open cut in the nozzle facing out and I belive that helps atomize the air/fuel so Ill correct that as well.  As for the screws on the side of the carb, Im not certain without getting out of my warm bed on this fine early saturday morning...... Crap, now Im obsessing over where theyre located... Well I might as well go ahead and burn a cigar while im up.

Yesterday Inswapped everything that needed changing. Still too much fuel but I dont have smaller then a 38 pilot jet. Im down to a 100 main. I also put the battery on a jump start/tender and the starter runns great , fast and strong while its hooked up. After removal Ill get 1-2 good cranks and thats all, so I guess the battery is going bad. Ill hold off on the battery because even with the stronger crank and spark, Im still gettinv waay to much fuel as the plug is soaked. Will adjusting the setting on the carb help? They are still set at manufactures specs.

It might help, yes. Try seating the screw, and turn it 2 turns out. That is the normal base line setting.

You didn't say if it was on the air box side or the intake manifold side... Or did I miss that?

The silver screw is closer to the airbox and the brass one is closer to the intake manifold.

And the fox ran round the bush.

There is a small screw that adjusts the idle mix, and a larger screw that adjusts the idle speed. The small screw is the one we need to know about.

Just looked it up. The brass screw is the idle mix. Yours controls the amount of fuel allowed to pass thru the idle circuit. Try setting it at one turn, and that 38 pilot jet you have. With a new spark plug it should start with 2-3 kicks.

Also try adding a new ground wire from any engine bolt to the frame, and the battery. Something like an 8awg wire will work. That may explain the weak spark, and dead battery
