No exhaust fuel line?
I was given a mint condition GMP competitor recently.
It's got an os max 61 heli engine on it. No idea about the age.
I can't find the exhaust port on the muffler to plug in the fuel line (so the tank's pressurized). Of course, the main fuel line hooks up without a problem. I've taken the muffler off and there is definitely nowhere to attach anything on it.
Any suggestions? I was thinking of maybe tapping into the cooling shroud and getting pressure from there...
