I started out having my wife do them on her cricut then moved on to a Brother scan n' cut. The rest is history 👍.
I am still small scale, personal use and for a few people...the Cricut works great for me. My wife complains that I use the Cricut more than she does.

The 805 I have was a cherry but it had bad chrome .Saved the piston and found a decent 850 cylinder .Ran good until I ran it out of gas.Then with a straight gas prime,by mistake I cooked it .Never one to give up I found a rough looking early model 850 with a good engine,cheap .Only those who knows those saws could tell it from the proper cylinder etc .Handles a 32" with style in oak .

Just a word IMO .I have the 805 another 850 and an SP 81 .Compaired to a Husqvarna 281 the Husky will slightly out cut them but the Macs have slightly more lugging power .Evidently wider power band . All stock engines except some relief work done on the mufflers .

Nice work on that 805 Mark! Vinnywv tore my saw down & cleaned it thoroughly,then put a new fuel line & filter in it & tuned it.Originally he was gonna put it on feebay,but we worked out a deal that was satisfactory to us both & I now have the 805.I can't wait to put this saw in wood!

Getting the engine in and out of the case has been challenging for me on the MM6. I know you must pull the starter rope out a foot or so and work the flywheel fins through the starter ratchet, but is still take a lot of tinkering... The saws with a removeable starter are much easier, good thing too since it usually takes 3-4-5 tries before everything works as it should. The most recent MM (110) ended up have an internal leak in the pulse pump (automatic oiler) and filled the crankcase with bar oil after the first go 'round.

Yeah it was a bit tricky going back together but easier than I thought it would be. I rebuilt the auto oiler and today was the first run so we'll see how it is after sitting over the weekend.
I upgraded the center bolt under the throttle trigger to 1/4" -20 bolt because both my saws had the original size bolt broke off or stripped.

The first time that I messed with a mini Mac, I wanted to make sure that the ignition was working right since I had just replaced the capacitor and cleaned the points. I had the bright idea to try to get it to pop off while holding the engine in my hands before I put it all back in the case. I squirted a little bit of fuel into it, chucked a socket in the electric drill, and turned it over using the flywheel nut. The thing started and did a lot more than just pop off. It gained speed as it went lean, and ran for about 15 seconds. That 15 seconds felt like an eternity as the thing got hotter, faster, and louder in my bare hand. I tried to put it down, but it was difficult to move around with one hand because of the gyroscopic effect of the rotating mass. The drill was still in my other hand. I decided that if it continued to run for just a couple more seconds, I would throw the engine down on the floor. Just when I was about to, it stopped running. I set it down quick on the bench but my fingers were still slightly burnt. I cussed out loud to the room, and looked around to see if anyone was watching. What a dumb idea. I’ll never do that again!

I had the spark plug out of the head and grounded it while connected to the coil wire then spun the engine on the clutch side with my drill on high speed to check the spark.

12 months ago did full rebuild on SP80.
It didn't run properly so thought must have not sealed the clamshell when assembled so put on too hard shelf till now. Went through the carb and intake again and noticed small tear on gasket under carb so made new gasket and problem solved.
Runs perfect.
Original timing numbers were exh 105, intake 65.
Have changed to 103 intake and intake 69, has much better trigger response than my PM850 and plenty of speed buried in 24" log.
Goes back on the shelf now.
Some photos for those who appreciate 1970's styling 😍
