an engine with low compression will run , but does not generate much power
.multiple possibilities. scored cylinder walls? piston rings well worn
and no longer holding proper tension against cylinder walls? if you do a
wewt test how much does the compression come up? if significantly , it's
time for the certified rebuilder to handle to operation.
