Jet',

I only reported the Cliff's notes version of what we did. When we plugged one side of the muffler, we had also still had the High end bypassed. We mainly plugged a side of the muffler to see if it would even run rich at all!

My tank is located pretty high up in the nose of the fuselage. I tried to mount it high enough to be level with the carb and high end adjustment.

Another guy somewhere on the forum, talked about the same problem and he ended up installing a stock muffler and the plane ran perfect.


Jim,

I know what you mean. I don't really want to run a pump, 'cuz I don't think it should be necessary. I'm convinced (is 90% considered "convinced") that it's the muffler pressure. I want to run the slimline to have a smoke system, but I'd rather have a reliable engine.

Also, I don't see a pic?

Thanks,

Mike
