Epoxy in the intake? Ms660

[Mastermind]

It looks like I'm going to be doing another 359. The last one I did, I elected to not do machine work on it because the intake was already at 80. I'd like to cut the squish on this next one, but I want to keep the intake up at 80...maybe even a little higher. Was wanting to understand best practice for doing the whole epoxy thing.

That seems like a good one to use this on Greg. Let me know how it turns out please.

Something to keep in mind Greg. Two stroke ports are measured in Time.....and by Area. If you have too much time.....make damn sure you don't add more area. In other words, on some engines you can get by with a little too much duration, as long as you don't fall into the trap of thinking every port must be widened.

Does that make sense?

Yes sir, that makes sense!

Question for you guys....when you are prepping for the epoxy, do spray some kind of oil on the piston so the epoxy doesn't stick to it?

I lay a thin sheet of paper on port then place piston back in. Keeps epoxy same shape as jug.
