If it was me I would drain all the fuel out and rinse the tank out with Seafoam and drain and fill with fresh fuel.  Put in a gallon of pure gas with 1 ounce of Seafoam and run for awhile. I've found it is very difficult to get the small passages in the carburetor cleaned out.

Very nice looking scooter.

Thanks! Not bad for $400 (or so I thought? haha) And I will give that a try tomorrow with flushing the tank, I should have done that to start.

I am thinking about buying a new carb for it, even though the one it has now is super clean (even before I pulled it apart), I'm just beating my head against the wall. I owned MANY carb'd motorcycles and have never had one fight me this hard haha

have you had a look under your belt cover? Problems there could possibly affect top speed. No blockages anywhere in the intake path or exhaust?  plug, wire and coil? CDI? front brake dragging? ...ok, now i'm just reaching...

Keep digging in and let us know what you find!

I have not pulled the belt cover, I am almost certain it is something engine related. It seems to happen worse under load (going up a hill or going WOT at low speed) When its on the center stand it revs up just fine.

Things I have done since previous post

-Remove and cleaned carb again, set float height, also removed intake tube from airbox and check all that
-Removed the intake manifold, everything seems ok but I am going to try and find a new oring for the manifold
-checked valve clearance, it was a little tight so I set it to .12mm
-checked auto choke, working properly
-checked spark plug gap and tested to make sure its getting spark

This one made it a little better
-I plugged the larger nipple on the intake manifold (the one for emissions NOT the one for the petcock)

Just curious did you drain all the old fuel from the tank and put in fresh fuel?  The first thing I would replace would be the fuel filter.  If they become clogged it will run like you described.

So it had VERY little fuel in it when I got it but I did not drain it, I filled it with a full tank of fresh 91, I assume that could maybe still be my issue, fuel flows very well. Where is the fuel filter? From what I can see the fuel valve is mounted direct to the tank and the fuel line goes right from that to the carb.


I ordered a new spark plug, thinking I should probably check compression as well. Also testing all of the ignition stuff probably makes sense, reading over how to do that is making my head spin a bit.

Thanks for the tips, I will work on getting some photos!

A small update, I did pull the carb and clean it, pilot is a 35 and main is 110 (I saw someone else post they had a 110 in their P150). Overall the inside looked very clean, hit all the passages with some carb cleaner with the jets out. Reassembled, same issue.

I pulled the plug and it looked a little lean, I am now wondering if it is an intake leak somewhere. I tried spraying all the boots and everything with some carb cleaner to see if the idle changed, it did not. Overall the entire engine area is very clean, none of the lines looked dryed/cracked and I did test the fuel valve, confirmed it is working.

I am going to buy some vac line and some plugs to do some more testing for an intake leak, feel free to chime in with any best practices or known trouble points.

Hey guys, I recently picked up a 2006 People 150 from an auction, it had about 950 miles on it and looks almost new. It was running when I bought it, started easy, mild hesitation when rolling into the throttle but it would not go over 30mph with the throttle wide open.

Air filter looked brand new so I pulled the slide out the top of the carb and noticed the diaphragm was pinched and not sealed all the way around, I reseated it assuming this was my low power issue and took it for a spin. Now it will get up to about 10mph and hesitate/lose power and then sort of come back on, if I baby the throttle it will continue to cruise but when I roll on to full throttle it falls on its face.

Just wondering if anyone has some pointers on what to look for, to me it seems like a fuel issue, possibly not getting enough fuel now that the slide/needle is assumably moving like it should?

Also, can anyone tell me what the stock jet sizes are? As well as the stock procedure for setting the idle air mix screw? I assume its so many turns off fully seated.


Thanks!
