I have defueled the plane and put 100LL in the tanks. I am still having trouble running up the engine. Any advise on what I should change or look at that the ethanol may have destroy ed? Thanks again=2C Tom From: tmckeon79@hotmail.com Subject: Yak-List: CJ-6 Engine trouble Hello=2C I am having some engine trouble and I am hoping your experience can point m e in the right direction. I have a CJ-6 with a Housai 285hp engine. I went to go fly one day and I s tarted to runup my engine. At low RPM everything seemed fine. Once above 1750 RPM things changed. The RPM needle (Manifold press needle would move in sequence with RPM) would sporatically jump around. When it would jump t he engine would chug as if it were about to die and then surge to life. Th is would happen about every 20 seconds. When I would cycle the Mags the en gine would immediately chug and start to die and would certainly cut off if I didn't quickly put the mags back to "both". This would happen with eit her left or right mag. I took the plane back to my hangar and looked at a few things. I pulled th e fuel filter screen on the lower left of the firewall=2C it was clean. I pulled the spark plugs from the bottom cylinders and they were good. (I ju st picked up the plane from a full maintenance inspeciton by Jim Selby in A ugust so everything should be pretty good). Of note=2C the primer was lock ed. I opened the top of the Magnetos with the local maintenance workers at my field and looked for any damage. We didn't notice any. Also of note =2C I have been using Auto gas 87 octane with ethanol. I have been doing t his for about a month. It wasn't until a week ago I found out this was bad and I was looking forward to burning off all the fuel in my tanks to repla ce it with 100LL. But due to this engine problem the tanks are still full of auto gas. Right now I am guessing it is either fuel related=2C or ignition related. Any advice would be appreciated. Tom PS. Previous problems with the pneumatic system have been fixed. Thanks. ________________________________ Message 5 _____________________________________ Time: 08:25:59 PM PST US Subject: RE: Yak-List: CJ-6 Engine trouble From: "Bitterlich, Mark G CIV Det Cherry Point, MALS-14 64E" There is a significant amount of fuel in lines and filters and everything else. Make sure you run the engine for at least 15 to 20 minutes before going any further. Make sure you leave it running long enough to get good fuel in there. If it does not improve, I will leave the next advice to a good mechanic. Most folks here are either aircraft owners or have watched others at work and have learned from it. Me included. That said, Dennis is very good on engines as is George Coy and a few others. If this does not improve, you just may have a very significant problem that you need to engage an expert to fix. Something that goes beyond educated guesses from the general public. Safety could be a real issue here.
