put new rings in craftsman 3.7 with LOW compression. All i can get now is 100 psi; bout what it was before replacing. Cant hardly start it but when i do compression is so low it wont idle and wont stay running at WOT. Dud all the normal stuff: carb, lines, filter, etc. even replaced coil with known good one since spark was nowhere hot enough. got couple of suspicions
Even thiugh both the slug and jug look good, no scoring, im wondering if clearance between them is too much. I checked new ring gap at bottom of ports and they were spot on.
Or - not sure if the jug is chrome or the piston. Either way, will that affect ring seating? Rings are ductile and are from greece
Gettin really frustrated here so all help is appreciated
