Another Carb Thread... OEM S9 Issues

[thebatman]

What up guys,
I'm going to try and upload a vid. PLEASE forgive the quality, bouncing for about 25 seconds. WTF? 
Anyway, i gotta question about a s9 issue.
Starts fine, idles fine...
Give it gas, she'll open up but then die out until you let go of the throttle...
Here is the vid..... What's your opinion???

[thebatman]

DAM... I sound red-neck as a mo fo there....
W.T.H is up with that?.. Same thing when i was on t.v, sounded country..

Anyway, i guess i should have done a lil more history.
OEM, Several miles on engine, probably 14,500kms. New base/head gasket.
Carb is OEM. She smokes good but will die out like the vid shows. I would not think any lean condition since all is oem.

I have a suspision in mind, for the noise, IDK if you could tell in the vid..
I can still hear it in the vid.  which i do not like the idea worth a sh#t..
I know for sure it's not the W.P, the var side looks good. Bearings tight on both sides.

I will have to rename this thread..

Have you cleaned the carb?  Sounds like a clogged MJ to me.  At what point in the throttle does it cut out?  Why the new head/base gaskets?  Did you do anything else internally?  Have you done a leak-down test?  If it's not the carb then I would suspect either a vacuum leak only at higher rpm's or an ignition issue.  Have you checked the crank bearings?  Hard to tell from your poor video, but something sounds a little funny.  That may be where a vacuum leak is also.

I think a vacuum leak too. It is starving for fuel. That is proven by the good restart. If it flooded it would be hard as hell to restart.
If a Batman superhero sounded THAT country... Id laugh my yankee ass off.

..it coulda been me talkin on the vid....

..no sh**!!!...batty, we sound the same..

                     


..to me, it sounds like it is starving for fuel....cant generate enough combustion to take those rpsm up....

Yeah, i cleaned it several times lately...lol
 Why the new head/base gaskets?  Did you do anything else internally?  Have you done a leak-down test?
There was a leak at the base gasket, so installed new gaskets. I never opened it up or anything.. It had run, found a leak=new gaskets....fired right up....well no right up but close..
  Have you checked the crank bearings?  Hard to tell from your poor video, but something sounds a little funny.  That may be where a vacuum leak is also.
The bearings APPEAR to be good. good and tight
THAT'S WHAT I THINK THE NOISE IS......A RUSTY BEARING???

I think a vacuum leak too. It is starving for fuel
A vaccum leak huh?...hmmmm...
She sure seems to be flowing good either by me or the engine running...done quickly.
I did turn the mix screw out to 2-1/2 and it wasnt AS bad, BUT she would want to shut down about 1/2? throttle.. MAybe worse under a load... Took off good ONE time, seemed to struggle afterwards. At about 6000 rpms it starts losing anything it was trying to get going..(i ain't that dam fat though... )...(230)

Gotta love that sh*t..

Yeah, it won't get the rpm's up worth  .

VACUUM LEAK!
Probably at the crank seals....Do a leak-down test!
Spray soapy water on the seals...if they are leaking...replace the bearings and the seals.
Sorry Bro!

[wordslinger]

...sounds very...airy....

I would not doubt any of it for a second...

On the af18 engines I can use Picks to pull out the seals without splitting the cases. Can you do the same w/ your engine ?
I also put a second seal in backwards to avoid dirt on the first seal. Hardware store 3 bucks...

Hey batman,

Might want to double check your float level.  It could be set too low, so that as soon as it starts drawing fuel up through the carb it empties out and can't supply the main jet.  At this point, even if it looks okay, adjust it so that the float closes the needle a little later than you would expect. Trying it out can't make things any worse.

Video's not bad.  It gets the point across clearly, which is what counts.

Cheers!

Were tellin' the guy to split cases, and Josh says  Look in the gas tank. Forums work when people post...

Your getting seals at the hardware?? 

Picks to pull out the seals without splitting the cases. Can you do the same w/ your engine ?
Yeah, those can be picked out as well.. That sound though, idk wth it is. . My 1st thought was like a "rustyISH" bearing or something which would of course would mean.....dissassemble

Suppose to be in class right now, but i'm hoping to get motivated enough to test that this evening.. it's cold, windy today.. dam, i need another red bull i guess..   Block off plates are alot nicer on a leak down test vs that dam "stopper" i been using.
I may have been hoping for more ease  ......imagine that tho..
Float would be an easy fix there    but that darn noise though..
DAM, i want MY S9 back up.
