Are these Irvine .20s converted glow engines or purpose built diesel? Is it a new engine? Generally, a tight fitting piston is a good thing, though too tight is too tight. I had to use a heat gun to start my Jett .35 the first time because it was so tight, but after a few runs it loosened up a bit. I can see an ABC/AAC with a tight fit being problematic for use with diesel since the diesel doesn't run as hot.
