Just to further add... The engine was lean when I started it, the intermittent engine note indicating it (Hunting) so I opened the needle valve 1/4 - 1/2 a turn. Once it was running smoothly I then leaned it out with the needle valve until it started to die and then when back 1/4 of a turn. When it ran the tank dry it stopped smoothly - an increase in revs just before cutting out would have signalled it was running rich and in a Free Flight model makes a very bad transition to the glide
I'm not !!!! Its for a mates Tomboy... but he could n't get it to run. Not surprising with the piston the wrong way round
