Well ive got a .15 pro in my ad2 losi. Now when it runs it runs great!. it eventully will stall its self out after about 10 min's of riding. And its very hard to start. it starts after about 10 min on and off cranking. And also i have to prime the motor over and over (finger on exhaust) it floods its self out bad but it eventually starts. ive tried new plug after new plug. (O.S. 8) and same deal. My high speed is out 2 1/2 turns my idel is 1 full turn out. And my low speed is about 2 and half turns out (flush). I run trinity monster gas 20% any help?

how many gallons have gone through the engine?

2.5 turns on HSN seems a lil lean i thought it was four. for factory.

I've had several pro 15's and HSN should be between 2 and 3, LSN should be about 2. Whenever I had a problem tuning mine I pulled the carb and cleaned it completely by pulling both LSN and HSN and spraying carb cleaner into all openings on carb to flush out crap. Replaced all o rings (traxxas sells a complete set of replacement o rings). My pro 15's were usually at 2.5 turns for HSN and about 2 or a bit less (1 7/8) for LSN. Idle opening was about 1/16 inch wide.

You might have compression issues. Do you know how many gallons of fuel it has seen. It sounds like it's getting hot and stalling out. That could be a worn engine or you're overheating it.

it has maybe a gallon and half trough the motor. Not much time really. its always been like this to. yesterday it had a brief moment where it started right up. but that did not last to long. The motor does get realllly hot though. and stalls its self out. then its almost impossible to start it back up. so i let it sit for half hour and it starts in 2mins or so.lol.

Those engines a trouble I had one fought it and fouhgt it finally got pissed off at it and replaced it with an os engine best way to go.
