Im getting ready to break in a GRP my first .21 and i like this method and found it really helpful but at the end of part 1 he was talking about the temps dropping after a couple of half tanks on the ground and i was wondering do you lean the highspeed or lowspeed to keep the temp up to 210 or do you just let the engine temps go down?

But I do not want the LSN so rich I die easy because its over rich( I always try and keep the engine running to prevent from having to start the engine over again). I will usualy set the LSN correctly after I feel the engine is pretty much loosened up well ( broke in). Also remember when you lean the HSN it will lean the LSN at the sametime to some degree, Hope this helps, Dave

prime
another question - when pre-heating the block with a heat gun, the pressure seems to push the fuel out of my primed fuel line. When I try to reprime before starting, it doesn't take. It has to cool down to about 140 before the prime will take.
I do have a relatively short fuel line, will try a long one coiled one like in the video, but figured I'd ask anyway.
