Crap, that brings back some memories from grade school.
Permanent Hearing Loss but .. she runs!
I just fired up my favorite PM800 after my rebuilt was completed early this A.M. Man. is it loud. A little smoky as I burn off the assembly lube. Here are a few pictures. See if you can spot some of the old technology I incorporated. I put an 8 pin on it and I am anixious to see how it cuts and whether or not the clutch will endure. Enough yakking.
Nice clean lines. I gave her a new flywheel cover and recoil cover. All grade 8 hardware.
I warned that this side looks funky. About .8 ci of exhaust opening; I may add more. I thought about making Mark a SS side cover for his PM850 muffler body, but there isn't enough room for his last name unless I go with some really tiny holes.
View from the rear isn't too hot either.

thats a sweet saw Ron. i'm glad to see that you made a muffler cover. i've been talking with David about making one forthat SP80 that i built for him. i like how you used a flat metal instead of bending the edges like the original, that keeps it simple. i may tackle that same job soon.

After seeing that muffler, I finally understand what a "woods" port job looks like!
I knew I was in trouble when the links were gone. Here are the pictures from the first post:

Joey, if you want a SS blank, I can cut you one. You can drill the holes to your liking. Just let me know if it is for the 4 sided (80/81) body or the five sided (850) body. I couldn't bring myself to use my NOS SP81 muffler. Same for my NOS SP81 chain brake/ clutch cover. I don't know why as I sold my NOS cylinder and gave Jacob (ChainsawmanXX) my project SP81E.

thanks for the offer, your comment on using SS reminded me that i've got some 304SS that is roughly 1/8th" thick. how hard would it be to cut slots and make louvers?

I bought it from a small local motorcycle shop. Faster than waiting for NAPA to get it in on an order and much faster than waiting for it to ship from fleabay.
I used it on the same day I bought it. Only bought it since everyone kept saying it was better to use than most other products.
And it was Threebond 1194, not Permatex Motoseal.

1/8" stainless wouldn't be too hard as long as you've got a decent vise on a good workbench. Cut the slots with the dremel, then open the jaws on the vise about 3/16", then use a cold chisel and a medium/heavy hammer to form the louvers.

I bought my tube of Hondabond-4 for about $8.00 at a local dealer. Same as Threebond 1194.
I don't know. The only way I could do that is to cut the slots (with what I don't know as I don't have a die cutter or dremel) and form the louvers with a chisel as Kyle stated. Ron
I'm glad everyone likes the PM800. Did no one spot the old technology? I'll post it tonight. Ron
Awful quiet around here today.
Where is everybody today? I worked on my suspected PM805 today. I filled it full of mix only to discover that the fuel line was leaking badly. After it drained down, I tried to start the saw. I got it to pop once but then I sheared the flywheel key. Remember our discussion about hard ebay fuel lines. Well, the old one looked new and was nice and supple but it sure didn't snug up tight. I installed one of my nice new flexible lines and it leaked almost as bad as the one I took off. I dug out one of the hard ones I had complained about earlier and I could see that the bulk head bulge was bigger. I put it on - all when well except I had to take the carb off to get it on - no problem with the flexible (but useless) ones. I replaced the key. And proceeded to wear myself out trying to crank the saw. I had spark and a new plug. I can't ever tell if I have prime something enough or too much. Do you guys actually pour a tablespoon into the cylinder? I have had good success in the past just dousing the air filter but not this time. As I said it is awful quiet around here. Maybe things will change later. Ron

I keep 32:1 mix in an old windex spray bottle and give the carb two squirts. One squirt for smaller saws less than 50cc

I'm trying to patiently wait for this "old technology" you keep talking about.
Ask and you shall receive.
I just knew that eagle eye Aaron would spot it.
Nothing hi-tech, as I said old technology:
