sh m28 p-3 engine
 

Has anyone had any problems with these engines? I have not yet neen able to run a full tank off fuel thru this since I have owned it. 1sT 2 TANKS AT IDOL AND cannot get it tuned to stay running and once it quits its 20 minutes before it will start again. any suggestions.

If you've got to wait 20 minutes before it'll run again, it's way too hot. What are your needle settings right now?

I had a really hard time with mine as well. I ended up resetting both the high speed and low speed adjustments backt to factory. i found that if you screw them both all the way back in "SLOWLY" then come 2.5 full turns out on both that is a good place to start. Make sure that you run the first few tanks rich so that you can break it in easy.

What you should see is heavy smoke and a thick grease / nitro goo like stuff from the muffler. After the break in period i have found you just have to adjust your butt off to get it correct. I have been at mine now for about 4 hours+ I almost have it so i can hit the breaks not kill the engine then take off again fairly well. Also from what i know as the engine wears in the adjustments may need to me worked on a bit more.

Just keep at it if you don't already have it figured out. This motor is insane once you get it broken in and tuned correctly. I remember having a little trouble at first getting it to work right to but once its perfect it will smoke anything on the block.
