Bench ran a new os 91 fx for one tank,ran fine.Mounted inverted in extra 330 with slimline inverted wrap around muffler could not get it to run right.Had to lean it to 3 and 1/3 turns out.The break in setting is 4 to 5 turns,and it still dies when i pull the glow lighter,and floods when it dies every time.
Tried useing the stock muffler with the same results.The tank is as low as it will go.Even if i relocated it.It is at the height that the manual recomends.I put the tank on the ground once and it ran perfect,but i cant fly with the tank on the ground so...This is BS. I spent a lot of money on quality stuff so i could just fly without problems,but here i am.Am i doing something wrong?
I am about ready to sell this thing and spend more money for 26cc gasser.Will i still have problems with the gas engine?
Thanks
