CARB PROBLEMS?79 Wing

Postby IVGOT2WINGS » Sun Jun 22, 2014 2:07 pm



I was having issues with my carbs, so i took them off cleaned the bowls and jets replaced them. I still had a problem, engine starts runs but with ruff idle, at this point i adjusted the timing checked the plugs and all the fuel lines and still couldnt get a good idle. SO I followed the steps to set the idle screws as outlined in the manual. I get this thing running what i feel is good and it does so for 15 to 20 minuites then idle drops and it stalls. Mostly if rev it 9 out of 10 it comes back but then 10 comes along and it dies. I take it out for a spin and it responds well until I hit a red light then she stalls.
So basically I'm lost as to what to do now. I really am just WINGIN IT no pun intened OK maybe just a small one. Anybody got any input something else I could try short of a rebuild, which by the way was done 4 years ago shouldn't need that again.
Really could use some HELP if any of you more experianced guys know what I should try?? Thanks and be safe!!!

You said you were having 'issues' with your carbs. What kind of issues? You said you removed them, did a simple cleaning and you're now having issue with your idle. Not knowing what problems you were having at first, it's difficult to advise you. But, I can suggest that you sync them. Your current problem sounds like they're out of sync. If that doesn't fix your problem, I suggest that you remove your carbs and rebuild them using Randakks kit and video. If you're not comfortable with this, send them to Mike Nixon or Pistol Pete.

pretty much same issue with the stalling, only happens once it gets hot. already synced them so as I said am lost hear. They were rebuilt in 2011 late 2010 so should not need that again Me thinks. I'm sure well hopeful I'm missing something, but thanks for reply!!

Exact problem with my 1000 and a 70's 3 wheeler.

The floats....Both bikes had the black composite floats.They would absorb fuel and sink raising the fuel level making it run rich.
I dried all the floats for a day then dipped twice in Polyurathane.
Dried 2 days and installed.problem solved.

Excellent advice. VM, I'm always hesitant to trust any 'coating' when used like this. I'm always fearful that it's going to break down. You're confident that polyurethane will stand up to fuel?

I didn't have any other issues.Be certain the poly is dry.It does resist gas.
I dipped mine twice to get a good seal.The floats even soaked it up.

Was it plain poly?

I've used this, Nelson Hobby Specialties water reducible polyurethane paint, with excellent results.

When I was cleaning the carbs the floats did seem poreis hopefully this is the problem great tip thank you I'm gonna pull them AGAIN and try this. Had a feeling it might be something with the floats as I eliminated most everything else I could think of with my limited knowlege, just wasn't sure how or what to do to fix it. Thanks again I'll give it a shot..... Ride SAFE!!!!

You can test this theory.
Dry the float for a few hours then put it in a container of gas and look where it floats at.Check back in a couple of hours.Mine would sink at least 2mm.
Enough to raise the fuel in the bowl 2mm and run rich.
My older ones would float half way up and after a day they were almost submersed.
