One on the carb and one on the pressure line going to the tank. Theres not any time on the motor and l see why! The manual shows the pressure and the crank case drain line going to the tank. MAN! This thing is a tuning nightmare. It will not run on just one plug, it will start on one, then you have to light the other plug. You will get it tune somewhat, then you try to fly it and you may get one flite out of ten. Don't see a (Pump) in the system? BUT! lt will not run with out the tuning valve in place on the pressure line and -or set up like a regular engine. l'd like to remove the pressure line valve and set it up like a normal engine. Do l need to replace the carb? lf ya don't mind, please give your input.
Mike, hows that Cub and 182 coming? Have not hard from you.
OldFart, Whats up? Hope alls good down there.
Happy Fathers Day
Is it a Big Jug 120abc like this:
If so, the carb is unique and Bill Robison had some tuning tips for it. Let us know and I will post my (his) notes).
BTW, mine has gold rocker covers, and only one plug. Some had one some had two, I guess.
If not a 120abc, then I have review and notes on the later 120aac from Clarence Lee/
Happy Fathers Day to all of you.
Sincerely, Richard
