Default breakin

During breakin you want the temps to be around 200. Adjust needles according to the temp. Also use tin foil to put around the head to keep the temps up around 200. Too low of temps are just as bad as to high of temps. Keep it around 200 might have to lean it out to get to that temp but its very important to keep the motor at 200 during breakin also make sure you put the piston (bdc) bottom dead center while you let it cool hope this helps and good luck

I couldnt even get my engine started with tin foil and the engine heated up to 240 degrees at first. I had to lean the LSN about 1/4-1/2 of a turn to even start. But, the needle settings will be alot different from somone that runs indoor in PA than someone who run outdoor in 110+ degrees in socal.

I don't run indoor. Well in the winter, yes. But I try not to break in any engines in the winter.

It's really worth the $30 to just buy a heat gun. A hair dryer will NOT get the engine core hot enough.

A temp gun is a nice tool to have also. Just try not to catch yourself tuning by temp.

By the video there is no way to tell. I would say blipping the throttle like that is worse for it than running long slightly rich runs up and down the street.
