Need Help Tuning!!!please

[momocorse]

I have a new .12 motor for my ofna OB4. Its an upgrade, but i can't get it running for more that about 10 sec! I have been trying to break it in and run it, but it wont run long enough. WHAT SHOULD I DO. I "tuned" it for about 3 hours. I need help. any suggestions are welcome>

Turn the screws back to the manufacturers break in settings, and go from there.
It should start and Idle. If your giving it throttle, it will stall because it will be set up rich for break in.
try throttling slowly to run up the rpms just enough to clean it out,
then Idle again.
After that, you will have to lean it out 1/8 turn at a time.
leave it as rich as possible, but so that its not over loading with oil and stalling.
Let me know what happens.

Thanks, i actuall just went out and re-adjusted the LSN. I leaned it out a little and it has helped in idle area. But I'm still playing with it. I went back to factory settings and had to lean it out a 1/2 turn to get it to run.
Ohh, and what type of glow plug do yall suggest. I need to get more and was going to order the ones yall suggest.

Thanks for the help. Any other tips will help. I need all of them i can get

What fuel are you using? That will determin my suggestion on your plug. Fuel oil content.

You can try a Mc coy mc59. Its a good plug for a .12 in my opinion.
Good luck and break that mill in right.
have fun
