OS 91 FX Leaning out, T/H sends a fuel inlet valve
I had the air bubble problem from the 91fx and I changed the needle valve to a Perry remote one and it fixed the air bubble problem.Then I had a fuel draw problem and fixed that with a pump.Now It runs great .I also had a heating problem with a incowl muffler and went back to the stock one.I really like this motor now it is setup right.It hauls my TF Texan like a Reno Racer.
