Was away for the weekend but sounds like there's still a bit of interest in this project! Had a good conversation last night with my buddy discussing project viability (e.g. moving from the artisin crafted cases to something more repeatable) and some next steps on the CNC side of things. He's...

prototype 2 (pho with a 572 clutch cover, half wrap handle) weighs - 16.6lbs topped off with gas/oil

Hey hey, it's been a minute. Sorry for leaving everyone hanging. . . I got pulled away on to some vehicle projects and then life got in the way and haven't signed in here for a bit. Yes and No. No real chances to run the saw* (it's not here at the moment) but also with the other irons in the...

I can verify this mtronic flywheel [1140 400 1210 A ] with opposing magnets creates spark and works as expected (e.g. the saw fired up and runs!)

Appreciate the assist on this! Thanks for confirmation, the one I have has counter weights across from the magnet, slightly magnetic, but nothing like the magnet side.

I've got a project ms362c project saw that I'm building. I acquired it in pieces without coil/carb (but I have an Mtronic coil and carb I want to use with it.) It currently has a aftermarket top end on it, but OEM coil/carb and currently does not have spark. I believe this is related to a...

Current Prototype #3 specs: for those who wish to recreate what I've got here Case - 365/372 variety with material removed to fit the diameter and width of the crank Chain - 24" bar with dukes hard chrome 3/8 .050 full chisel skip tooth Cylinder -57mm 390 big bore from wolf creek (non-Titanikel)...

Got a chance to get a bar and chain on it and a couple test cuts in some ash. Did a video of side by side cuts with my 500i. The saw I ran was the 500i, but looking at how close the numbers for cuts 2 and 3 are, I am chalking up 500i's 1st timed cut to not using as much pressure as the...

Running echo red armor @ 40:1 Piston / cylinder look decent. wiped things down, tweaked the carb slightly and it doesn't seem to be dying at idle, so I'll start heat cycling

3rd run, getting it tuned in a bit more, I think I've almost go it dialed in so it will rev and won't die after sitting at idle for a little bit. Assuming things look good once I pull the muffler and check things over one last time I should be able to get some heat cycles in over the next week.

ok, I believe I found the source of that knock. I sheared the timing key on the flywheel when the lock washer came loose. I happen to have a spare (as I'll be doing prototype 4) so I swapped the good one on. I figure this one can be used later for adjusting timing if I need to. Also added the...

Alright. after searching through the bins for a bunch of random parts along the way... Got it together. I have a couple parts that still need to be ordered. But first fire is a success! Long form vid (skip to 45 seconds if you don't want to see me yarding away on it...) - I didn't hear it...

Parts arrived over my lunch break! I installed the new seal and it is now holding pressure/vaccuum. So I started pulling the rest of the parts out to finish the build.

Yeah, I don't have an actual 385/390 to reference but from what I can tell in my research they changed their bearing style to move to an integrated seal (like the 562 series saws.) Here's one I found...

Me too! If it works, the next prototype will need some additonal case trenching on the clutch side to case match the transfers. And when I pressure vac tested last night and had a small leak around the crank bushing, so I've pulled the seal and bushing out and did a small amount of 1184 around...
