I just went throught this and scared the crap out of me @ 70 lbs. So I made some calls and found out to get the best result with a compression test and not a leak down test.

1 Make sure battery is fully charged.

2 Make sure you use a good tester not a Harbour Freight.

3 Push the throttle to the floor when cranking.

I ended up @ 130lbs up from 70 after making these changes which was a little low but my valves were extremely tight so after the valve adjustment I am positive it would read where it should. I do not know for sure but I believe the 660 should be around 185 lbs.
