Finger Ports???????

Do they work?

 

[Chainsaw Jim]

Yes. I can't wait to see a vid of that 3120 that I thought was a 394 when you're done. Lol

 

[Mastermind]

LOL

This is a 3120. One of 4 that I'm doing.

The ones Dave Nieger aka Big Dave put in my 7901 and 084 worked. 7901 was run with without. There was a difference.
Had a 066 with them too, Henessee put them in from TN.

Seen them work in 181 281 saws too.

Still to me porting is more important then all the other stuff now days being done. If you dont have the porting right it still aint going to cut it.

Those are some big banana's .

This method is so much nicer on the rings than widening the uppers.

I think on larger saws they help out...they are a must when running alky...I tried them on a o44 and couldn't tell a diff...

In my 440 hybrid ,they raised the loaded rpm's in the cut ,the exhaust tone sure sounds good bouncing off the trees .

I have them in my 046 race saw...but it runs 30%

They ARE A LOT OF WORK!

my 'mini fingers' aren't nearly as nice as yours, but the saw cuts good. Got a new compression tester, 180 PSI reading on it.. I can't imagine pulling a 77 cc saw over with 220.

Is this your std 3120 port or more geared toward gtg type cutting?

This is the way I do em all Keith.

Isn't it nice working on 60mm jugs compares to 40mm and smaller? so much more room to move your tooling and get it where you want it.
