I have a 1951 8n that has a rebuilt engine. New pistons, rings,
sleeves, valves ( valves were lapped) , bearings, etc. the problem is
I have low compression (~85 per each cylinder). And the engine runs
a little rough. Will hesitate on take off. I have checked all the
electrical (at least to my knowledge) and can find no reason for the
rough running except the low compression maybe. I have spark to all
plugs. Timing is correct. Can mark is lined up with crank mark.
Wires, coil etc are good. It does not burn oil and I see no smoke
from tailpipe and no exhaust gases from oil breather. I'm at my wits
end. Could it be that the rings are not seating ?? What could I do to
get them to seat if this is possibly the problem. Thanks
