Ok
1st...many thanks to Roscoe for the good advice on how to hook up the motor (quickly) to do a compression test.
With a little heavy gauge wire it all worked well.
The highest results obtained were:
Top cylinder: 142 psi
Middle Cylinder: 132 psi
Bottom Cylinder: 136 psi
So...I think that news is relatively promising at this point. The maximum spread is 10psi or about within 7-8% max. The test was done with a little bit of two stroke oil in the cylinder. I added this just to make sure there was a little bit of lube in there prior to spinning it over.
Now, I'll feel ok about getting the new impeller in there and then the (good used) lower unit bolted up. I have a feeling after that....I will need to look at the carbs and then some electrical connections before trying to actually start it up....so I doubt I'm done just yet.
......what a great bit of basement fun on a saturday morning...sure beats house cleaning....makes we want to do it all over again.
Cheers.
