+2 The conrod takes alot of the abuse while starting a cold engine, plus it helps to heat it to take a strain off the starter box. Some engines I have found to be different as to heating before starting the Os i didnt have to heat as much as my current GRP, that sucker I had to heat every time for the first gallon.
