Subject: Re: Pietenpol-List: continental engine/carburetorLes, Thanks for your imput. I am going to open up the carb (stromberg) today and look things over. I have had three different carbs on and they alldo the same thing. I have plenty of fuel flow to the carb, When I frst start it up it seems to get into the higher rpms which might be bowl gas but then dies unless I just idle. I have parts ordered for a marvel Shebler (venturi) but are slow in coming if they do. Thanks again Ken Conrad in warmIowa (50)________________________________________________________________________________

Subject: Re: Pietenpol-List: Piets and spinsI used to do spins in the Ford powered Piets all the time...I once spun down from 5000 feet to 1000 feet over White Bear Lake...lost track of the turns. Make sure the CG is not aft of 20 inches, and be carefull if the airplane is ashort fuselage model with a lighter engine up front...usually these ships havethe wing moved back, making the nose quite long, and usually the landing gear is covered, compounding the problem of too much area out front. Bernard never wanted us to cover the gear legs unless the airplane had a long fuselage,for better spin recovery.Forrest Lovley________________________________________________________________________________

Subject: Re: Pietenpol-List: continental engine/carburetorThe non-metal needle has been suspected of causing problems in the Stromberg carb when auto-gas is used. The additives MTBE and TAME seem to affect (swell)the needle. This has not seemed to be a problem when using aviation gasoline (100LL) having a greater purity and far less additives.I through away my plastic needle and went with steel.________________________________________________________________________________
