Looks like its right above the Cav plat right behind the water tube on the new foot which is bada$$ by the way! May add a 1" hole to mine make it louder don't care too much about gaining any out of it. Already gonna be like daylight and dark difference between the new motor and my Etec I had!

What degree timing are most if y'all running? Max advance or stock factory?
timing?

timin , if your spinin to the rev-limiter stock settin is good, past like 5800rpms to much timin is goin to clip the piston crown at the exhaust port window, she will stick the top ring and it's over, done, last. the more timin the harder she will pull, but you need to pull the timin back as she passes 5800rpms or she will fight her self and melt down. there are ways to get max advance at low rpms and dump off timin as she revs up............

the 59cid mercs don't like advanced timing they perform well up to 7800 rpm with stock timing.

Jon builds fast motors jetting is very important on how the motor will perform. their reeds are also worth spending the money on. If you are assembling it yourself clean it with soap and water real good before putting it back together. also if you removed the rods change the rod bolts.
