well, on the 2nd weekend out of break- in Noticed a miss and removed the plugs to replace thinking they were fouled, Noticing 1 of the plugs (PTO cylinder) had the gap bent down on itself. didnt think much about it and changed plugs. Runs great. Took out on the lake today, ran it for about 2 hours, same problem, started missing with a little noise. ?? Took home and did compression test. (not good) MAG cylinder-150 psi--middle cylinder 125 psi--PTO cylinder 25 psi....
What do you pros think happened? Broke ring? Crank bearing failure and piston slapping the plug? Did replace pistons and upper bearings but no crank work at time of rebuild. The oil pump is pumping just fine..
no cards or flowers please...
