Here's a question for you folks flying the A-65 with Stromberg carb. Engine won't start. Fuel is flowing from the tank, through the valve, through the gascolator, all the way to the carb... all just fine, good flow. But no fuel is getting into the carb. Regardless of throttle position or anything else, she won't fire due to no fuel.Next step is to remove the cowling and try tapping the carb body to see if something is stuck and can be loosened up. Any other ideas before we go dismantling the carb? It has no mixture control and the engine has been shut down using the mags, not by closing the fuel valve and running the engine till it quits.Thanks.Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Date: Tue, 31 Aug 2004 09:44:22 -0400

You could try removing the nut on the bottom of the carb bowl to see if itis a stuck float. Take a small screwdriver and try raising and lowering thefloat. If not it is probably the seal on the needle valve or a clogged jet.Have you used auto fuel with alchohol it it? That will ruin some seals.Thats what happened to mine.Dick----- Original Message -----

Oscar,I am NOT a mechanic, but when I had the SAME problem, amechanic friend of mine took out a small bolt in the carb and shot some gas in there. It then fired up on the first or second blade. Some folks say once the engine fires up the float the actsproperly and then engine/carb work fine.In my case, it turned out the carb needed to be overhauled(the idle side of the carb was gummed up from sitting so longwith car gas)......long story.My Stromberg has the mixture wired to full rich so I have tocut off the engine using the mag switch.Hope this helps. I know there are a lot of pros on this list with better suggestions.Mike KingGN-177MKDallas-----Original Message-----

Thats exactly what I did when I trailered a GN-1 from No. Cal to AZ. Up to90mph and 900 miles. Everything went well.DJ----- Original Message -----

Subject: Re: Pietenpol-List: fuel flow problemOscar,Sounds like your float is stuck. Is it the rubber tip float needle ? Pull the plug on the bottom of the carb, and if no fuel flow there, then tap on thecarb. If there is fuel in the carb, and fuel flow is normal out the bottom ofthe carb, then you might as well check how much flow. There is 128 oz per gallon, and lets just say 5 gal per hour burn rate. Thats 640 oz. per hour, or10.6 oz. per minute. Check and see if you get about 11 oz per minute fuel flow. If you do, then put the plug back in. If it still doesn't start, then trythis - With the mags OFF, open the throttle about half way, and flip the prop backwards about 10 blades. Mags ON, throttle idle, and try to start.Chuck G.p.s.
