Great job sir.

All done but the test and tune portion. Did a rough tune on the high jet It had to go in and lean the saw out as it was way too rich. I would have never expected that.
Talk about loud! Now I'll keep you all in suspense until I get some videos posted of it in big wood with the 48" bar

Great job sir.

It's my first build thread. I just aped (copied) you.

I have learned alot from your build threads so I put this thread out there on a not so common saw.

The compression came out at 160 psi hot which corrects to 180 psi at sea level due to my 4200' elevation here. I'm thinking it my be more because when the saw really kicks, it yanks the starter cord out of my fingers every time. I can barely pull on it cold without the decomp release, and I got to 160 psi hot with some week ass pulls.

I have to drop start a lot of saws.......even the big ones. Having a long bar on it makes it tough though.

My longest bar is a 32", that stihl bar is 48" or 60". What a PITA to get it on, and the chain mounted correctly.

The easiest way to drop start those big saws with long bars is put the tip on a log and hold the trigger handle and drop it down. Just got to be quick to get it off high idle if there's not a chain brake to keep it from trying to run away.

Nice build. Thanks for showing the pictures and the detail of your work. I'd say the trumpet muffler may not stay on there long, might be wrong but I bet it is LOUD!

I like that trumpet...bet that sucker is gonna be Loud. lol

 

[Mastermind]

Ear plugs, and muffs. Still probably gonna hurt.

You need to fab up an electric starter for the stihls it would work anyway

I've got a test and tune session planned where we are goin' to put that saw into some big wood on Tues, and on Sat. as well. Videos to come.

 

[ft. churchill]

That saw was running alot of RPM's before, I kinda did some things to trim back the high rpm's, and built more for torque as he only runs big bars with that saw. I did not like the idea of running and old saw with a 8000 rpm maximum limit on a diet of high rpm's. We shall see.

Very nice job sir

I'm going to do some more tuning today. The spark arrestor screen will be removed as the saw had more "sparkle" without it before. Retune the carb. I'll get some more videos in a big cottonwood log.
