bought a Craftsman 3.4, equivalent to Poulan 3400, and trying to rebuild it. compression 120 psi. took jug off for measurements:
measured ring gap - 0.101"
ring pin width - 0.060"
per my calculations the ring gap for 1.8025" measured cylinder should be between : 1.8025"*0.004+0.060" (0.0672") and 1.8025"*0.008+0.060" (0.0744")
ordered rings from Greece and measured ring gap. It is 0.101”. am I missing something or are these rings too small? is this gap acceptable? is this the standard gap for the 3400?
help greatly appreciated.
