I have inspected every conceivable thing on my engine and have not found anything that points me in the right direction to correct to my engine problem. Right now my carburetor is disassembled on the work bench. I was hoping to find a bad diaphragm or other abnormality in there but nothing jumps out at me. I have a new diaphragm that I am going to install after I thoroughly clean and dry out the carb. The Ellison carb has a pressure vent (approximately 1/16" diameter x 3'' long) from the mouth of the carb through the body leading to the diaphragm. After I took the carb apart, I blew through this vent and noticed there was some gurgling sound in there as if fuel, oil or water were in the vent. This vent should be dry without any obstructions. The purpose of the diaphragm is to apply pressure on a spring loaded fulcrum which meters the amount of fuel allowed into the carb. If this is blocked or partially blocked, the performance of the carb would be affected. I hope to have the carb reassembled and back on the plane Sunday. I will let you know how the engine performs. I would do it tomorrow but I am getting up at 3 AM tomorrow to make the 500 mile drive to southern Illinois to return the trailer that was loaned to me. I should get there right about lunch time so I can take Gary Jones (the trailer owner) out to lunch. I think I will buy him a PRIME RIB lunch for letting me use his trailer. Total trip will be about 1000 miles in one day so if anyone wants to call me on my cell (262-366-3319) and chat, please do as it will help pass the time.
