Ok Guys,
Here's a little question for you. I just got the engine running tonight, for
the first time in a number of years, and decided to do an unloaded compression
test(all 4 plugs out)
My readings were, front to back (1-4) 130/110/150/150 Number two seemed low,
and 3&4 seemed high. I wet tested #2, and there was no change.
My engine is a GD 1250 Herald engine, I am unsure of the exact bore- stock or
rebore I don't know.
Could the difference be caused by the lack of run time, and will level or
improve with use? I also wonder if it could be the valves need looking into- I
just adjusted them, though they were pretty close on exact. (I only needed to
adjust about three out of the eight)
Any thoughts or suggestions would be appreciated.
