Stalling
I got this engine 2nd hand right after break in (PTM GoTech 5 port). I just fired it up for the 1st time today and if I let it idle for more than say 10 seconds (sometimes not even that) it stalls. Also when I blip the throttle, I'd say 10-15% (while it's sitting on the starter box) it stalls.
New to nitro so not sure where to start tuning. They guy I got the engine from had leaned it a little but said it was not at race tune yet. Running an OS P3 turbo plug and Byrons Gen2 30% Thanks! |
Did the pinch test, and the RPMs raise just enough to not engage the clutch (M2C medium/normal weight, .9 springs) from all the videos I've watched on tuning this seems about where I'd want it correct? The top end needle seems a little fat and I get lots of smoke when I blip the gas, then it stalls.

I leaned out the LSN a little bit at a time 1/2 a turn, seems to idle better and longer now but will still stall when I gas it. Uploading a vid to you tube right now. be back in a few with it.

just to add to mr twister, make sure the temp on the motor is above 200 before you do a full pull. Also, wrap that head with foil just until you get the handle on it.
