Hey dmessy dude what was your comp pressures

[9675hpforce]

I have tried to find comp numbers for the 3cyls with no luck. My maual says it can't be more than a 15psi change?

Your compression should be 135 to 145 on all 3 cylinders.

After warm up, I read my compression at the dock as #1 -122,#2 -#120,#3 -120. I had replaced #1 piston and bored it to spec. and reused #2&3 pistons/rings as they were in spec. Still runs strong 100+ hrs. Hope this helps...
