Ok....check out this drawing.

I got it now. I was missing the part of combustion chamber.

Do you factor in the volumn of a tapered band when you mill it flat?

Randy, are you cutting a taper? 2°??

I've just had to arrive at the amount I remove from each cylinder by trial and error. I keep very good notes, and have a spec sheet for each engine.

No sir. I cut the squish band flat. I do round the edge where it meets the combustion chamber though.

I'm just now getting ready for the port work. As guys can see, the way we port a saw is far more involved that just a widening of the ports......

 

[Andyshine77]

Now we begin to port it.

How dare you copy my techniques.

Here you go.

That's just to throw you off, he's trying to hide his technique from Brad. He actually uses a sawzall to rough it in and horse rasp to give the ports that mirror finish.

Now, I'm trying to decide how much I should share on my port work..........I've spent a lot of time learning how to get repeatable results on the port heights.

I'm of the belief that knowing how I do it, and actually doing it yourself is two different things, so I'm just gonna spill all the beans here.

This is my spec sheet for the MS461....
