Hi

I have been running in my GRP .12 MRT motor on RunnerTime fuel and i am having an issue with it.

I have started to lean the HSN and since doing this it now runs on for awhile and then comes back to idle. I have been using the MyTSN engine tuning guide and have tried everything and it is all the same result...

I am starting to think i have an air leak, but someone told me at the track today that you can't tune an engine until it looses it's pinch and that is should contine to run fuel through it?

Any thoughts?
