I will now list the sizes of the improved flow of the ports.
Exhaust port cylinder side
Stock=27.13 mm wide
after=31.79 mm wide
stock=14.08 high
after =14.95 high


Intake port cylinder side
Stock= 28.71 mm wide
after= 30.71 mm wide
stock= 15.08 mm high
after=16.15 mm high

piston windows
Stock=6.92 mm wide
after =9.60 mm wide
stock=12.34 mm high
after = 15.34 mm high

exhaust port at muffler
stock=28.51 mm wide
after= 32.65 mm wide
stock= 18.83 mm high
after = 22.15 mm high

Piston skirt width exhaust side=33.87 -31.79=2.08/2=1.04 on each side for seal
Piston skirt width intake side= 33.85 -30.71 =3.14/2= 1.12 on each side for seal
The muffler, heat deflector and gaskets were ground to fit the exhaust port.

Jerry If you do not have a proper notebook, I can post you one if you wish!

Very nice work.

Thanks for the offer, all these measurements will be recorded for the owner and I keep a copy in my log book, these rough notes work best for me in the shop.

How do you figure what your after #'s are? what math is involved?

 

[pioneerguy600]

Thanks!! This makes a lot more seance now.

That was the intent, hope it helps.

Lookin good Jerry. Are you going to post your before and after measurements on the ports and piston windows?

Yes at the end.

i'm liking that muffler!
nothing crazy, just a better performing stock looking muffler.

Yes ,thanks, this is how I do most of the Stihl 044, 066 and 088 mufflers.

Thanks for posting these Jerry.

I am with Matt, all these threads help me understand even more. I also had somebody talk to me about porting the other day, kind of a hands on teaching and it helped tremendously


How do you port match the muffler? Take measurements on the cylinder port then transfer the numbers over to the muffler?

Thanks LP, I actually make a template for each model of saw I do, cut and file it to size and use it over and over, it positioned by using bolts in the cylinder that hold the muffler, mark the aluminum cylinder flange, remove it and mount it to the muffler, scribe the opening and then grind to fit, also grind out the muffler gaskets.

Nice work!! Looking forward to the finished product.

Thanks Will, this is just a rough woods port job but it wakes up the 044`s quite nicely.

Ya, I'm sure it does. My old 044 will stay stock I think.

Hi JJ, my Canadian buddy Bruce.

Yes, I know Bruce. Great looking work Jerry, I'm sure it will be an excellent runner. No aviation gas needed.

Thanks for posting these pics Jerry, it was the piston windows that I still had the most questions about. I'm doing a 028 super right now, I just put up my tools and came in, I've got my cylinder finished and plan to work over the piston in the morning. I didn't know how much I should open up the windows, but after seeing how much you opened this one I now have a better starting point. Great looking work, I think you may have done this a time or two. Thanks again for the posts, rep sent.

Good work and thread Jerry.

 

[pioneerguy600]

Great work. Thanks for the insight. These threads are very helpful.

Hope it helps some of the members that have not started porting or even some that are just getting started.

I have a couple 044`s that are not ported, I don`t run those ones though, I can`t stand to run a stock saw.LOL

Yep, Bruce is a fine fellow, keeps a steady stream of saws coming my way. LOL

i really want to get me a busted up 044. My old boss has about 50 of them & 046s. If I could just get him to part with his stuff(from old diesel stuff to saws) I could make him a ton of money on ebay.... the man has probably 300 lbs of stihl/husky parts dating back to the early 90s. all of the old stuff has long been disgaurded:taped:. He started out running pioneers, mccullochs & stihls. He said "home-a-lites" where under powerd and heavy. . .

He is a good guy with a good nose for finding piles and piles of project saws. I'm just glad he's running modern saws now for his firewood instead of beating himself up on those old dinosaurs.
