066/MS 660 port #'s. Please share your stock #'s

An 066/660 that is at 100 on the exhaust is a fine unit to have. Most of the time 98 is as low as I get the 660 jug though. I take out .060" from the squish, and set the clearance at .022. That gives me about 210psi, and I don't want to go any higher on a working saw.

I don't finger port many saws. Only a few really.

I do like them in some models very well though. The 064 jug is plenty thick, and that makes it a great one to grind them in.....

I just used bridge ports in your 064 Ted.

My 064 has a 066 jug. Would you still finger it?

When it comes to 064s, that one of AndyDodge blew me away. That saw is a runner.

Is there ever an issue with the plating not going high enough that you can't cut enough out to get your exhaust where you want?

Brad, I just did a 064 with a red light 066 jug, with finger ports......it's a pretty good runner.

No Ted, the rings are about .140 down the bore if you include the squish clearance.......no worries.

You may have to learn me how to finger a saw, lol

I use a very aggressive burr when I cut them. They really aren't hard to do. You will need a way to measure the bore thickness though. I found these, and got a set....

They just measure in .01" but work well for my needs.

It's easy. Lay finger in cylinder. Trace around with sharpy. Grind out inside the lines.[emoji12]

There have definitely been times that I wished I had a tool like that. Putting the exhaust at 80° on my piped 390XP was a scary proposition! I may just order a pair of those right now. Thanks Randy.

Well it certainly got weird in here in a hurry

Now that made me laugh out loud

They are made of plastic Brad.......they work well enough though.

I cut the top of mine in with a 1/16" thick cut off wheel. It can make a nice square top if you don't bump it accidentally.

Are you running a stock piston, just backwards?

 

[Deets066]

The 066 as it is now, I'll post up numbers and new pic when I'm done

Brad you are welcome to come run that saw anytime, fwiw

 

[Mastermind]

Have you put much time on it yet Andrew?

 

[fastLeo151]

I've run it a little bit, I really like it. Ive yet to find some bigger wood to stretch it out yet

Yes for the most part.
