Hey Riverdancer,

I tried it and your right you do need to keep the throttle up until you land.. Im not sure if I have the carb adjusted right or not,or the ignition isnt right.. Are you running yours on 4.8 or 6volt? I've got a 6 volt on mine maybe thats it.. Sounds kinda burbly.had it to lean on the ground and when I reved it up she wanted to stall so I richened it up some.. it wont stall but it's just not smooth.
What kind of muffler are you using? Mine is a brisson look alike,I had a friend make me one up to their specs..
Take it easy,
Frank
