Thanks for the replies.
Keith, I did what you said and confirmed it with a friend who bought the same motor.
The Hi speed is 2.5 turns out and the low speed is 6.0 turns out.
GTSUM, there is a super amount of compression so I will add the extra copper shim.
I bought a Hudy break in bench and ran the first tank through it. The tank took 45 mins!!!! What the? It will take days to run it in and I'll be deaf by the time I'm finished.
What procedure should I use running an engine in using the bench?
Heat cyle, Forced heat cycle (keeping the engin running and richening it to cool it or the Hudy way in the manual (varying revs for long periods and different mixtures to change temps and running it continuously)?
I thought keeping your engine at consistent revs while break in was not a good thing as it will wear in accordance with the force applied by the engine at a particular rev.
Please help!
