help! wing runs poorly!

[chief771]

Hi all. I am happy to say I got my wing running! Unfortuately not vry well. It pops and back fires through the carbs and exhaust and will run for a while then floods out to the point that gas is pooling in the plenum. Any suggestions? Not sure where to go from here.

Sounds like it's time to agonize over the carbs for a day or two.
There are obvious problems you mention....pooling gas in the plenum....your gonna have to fix that first(floats and/or needle valve problems)..
After the carbs are 100% and bench tested first.(fuel level and slide action) tend to the valve adjustments and check the timing belt marks,then sync the carbs.
Get the ignition timing perfect....especially if you have points(split the difference timing method)

As Virgil states, you have a problem with your carbs. You need to remove them, clean them & adjust them. If the carbs are not correct, you will NEVER get it running right.

Thank you everybody. Looks like I will be pulling the carbs today.

Pulled the carbs yesterday, reset the floats, put it back together. Went to bench test the carbs. I put gas in a small container with a connectio for the hose. Turned the bottle upside down and the gas just poured in and did not stop. I saw the gas pool in the plenum then it came out the intakes. Seems as tho there is very little if any gas getting to the float bowls. Maybe one of the passage ways to the bowls is plugged?

I don't. Know where to go now. Any ideas? Thank you very much in advance!

I assume you checked all the float valves when you cleaned the carbs? If yes, then you might have a float that is not floating and allowing the fuel to flow continuously. You really need to try and see which carb (Hopefully not all of them) is allowing gas to flow through into the plennum chamber and then really concentrate on that one carb to fix the problem. It really cant be many things, either the float valve is not operating, the oring between the float valve and the carb body is leaking, or the float is incorrectly adjusted/not floating..

Pull all the bowls off.Turn the carbs upside down.attach a hose to the fuel inlet and just blow air through it.you'll hear where it's leaking out.don't use a compressor,just blow down the tube.

There's a big-ass string looking o-ring that goes between the plenum halves that will make the kind of puddle you're talking about- if you think your gas is coming out before the float valves then check that one. I had enough fuel coming out of that one to 'hydro-lock' my motor- got out lucky with just a broken valve guide, but still...

Check the big plenum o-ring I refer to, as well as the ones between the carbs and the plenum.

thank you for that reply. I got into the carbs today and found I had set the floats incorrectly and they were not coming up far enough to shut off the fuel. I did have lots of gas in the fuel bowls. Uff da! I reset the floats and I will bench test them again tomorrow.

That's really good news~! Yeah, I think the spec. is 15mm - do the measurement with the carb rack on it's side so the floats don't have any weight - free as possible. You'll get used to these things - you'll have too! -Once you've had 'em apart in/out a few times it gets easier- take your time, meticulous stuff- attention to detail big time

Best wishes-

I think u will find it is 21 mm...not 15. Measuring from the raised lip

Boy howdy! I hope you caught that one in time ta avert disaster! Yeah, it's 21mm (I've even made guages to assist in this operation-) I guess part of the reason I wear this med alert/dog tag that says "American Veterans with Brain Injuries" is to remind me these things are something to be constantly diligent of... (I wonder where I got the 15mm? ...hmm, no telling) good save!
