Seems as if the "factory settings", on my P5 anyway, were to rich on the LSN to even "pop" ... leaning the LSN took care of the issue and with a little over a gallon on her now, starting with Comp. Heat. is not a problem.
Oh yeah, one more thing ... before I attempt to start a brand new engine, I always pull the glow plug and drop a few drops of light machine oil down the cylinder ( I happen to use Marvel Mystery Oil ) and also put a few drops of oil through the carburator, and exhaust port. Install engine and then spin her over for a couple of seconds. Install glow plug and commence breakin.
Yeah I did lean the lsn. Its still out from flush but I would say I turned it about a turn from what the factory set it at. Just finished tank 4, and I have it running on the box, still blipping the throttle about 1/4 throttle. Temp is about 195. Tried running it on the ground but the hsn is still way to rich. Gonna lean it out a little tomorrow and put it on the ground.
