A few years ago my dad got me a Volcano S30 (SH .18 Engine) as a present, and I just finished breaking it in when one of the controller arms broke. So it sat inside for a year or so until i picked it up again, and fixed it. The engine was a little tricky to get running, but i can get to run, problem is when I go full throttle. I can roll through the throttle up to about half and then any further and it just kinda cuts and dies. When I hit about 1/8th throttle it gives off a trail of a good trail of smoke so I dont think its too lean. Past 1/2 throttle it jusy kinda gives one last puff of smoke and the engine cuts. I tried tuning it leaner with HSP needle slowly and the problem just slowly gets worse as i lean it, cutting at a lower rpm. And going any richer it just doesnt want to idle properly and will die and then wont start until I lean the HSP needle but to where it was. Any suggestions would be welcomed, thanks! FYI I have new gas and a new glow plug. (Sorry if this the wrong cars subform to post this on, im new on this site.)
