First attempt

Oem

Dang, that’s crazy timing for an oem cylinder

Need to raise the trans about 20
Lower intake
Raise exhaust

That's the plan. What about that hump in the transfer covers? I've got them tapered at the moment, or should I grind them out ?

So I checked it again and I came up with roughly the same measurements.
I took some small stainless wire (.032) stuck it in the ports and this is what I got.

114
139
71

Checked three times and on average I get .011" per degree of rotation. Wire measures .032"

The suspicion came from 144 on the transfers. You actually meant 134, which is about right

piston is up against an .032 wire hanging in the transfer right now.

I’d Probly leave it in there

Yep. 139. I figured 4-5* for the solder. So 134 or 135 would be the transfer opening, not 144 like mentioned earlier

Given what you’ve done to the base, 110 - 134/5 - 74 would’ve been about right.
Earlier, you said 144 on the transfers

Well my del cheapo air pencil grinder died on me. The mandrel that holds the collet came loose and wobbled around making it impossible to use. I got it fixed and back together but it no worky no more. I'll Jack with it tomorrow.

I made a little progress before it gave up the go.

Your work looks great. Helluva lot better than my first few.

Foredom handpieces are very reasonably priced and are of good quality.

Thanks for the kind words, we'll see how the first finished product turns out. This could still go either way.

Yeah I was on ccspecialty last night. 1k for a foredom with two hand pieces. I'll need the 90° tool if i want to do my other saws.

Check eBay, can get a reversible motor, flex shaft, foot pedal, and hand piece new for $100 usually

Can get a foredom kit with straight handpiece for under $200. Would let you finish this saw and then get a 182amc later...cushion the blow a little if it’s needed.

Harbor freight flex shaft kit will get you by better than a Dremel for $50 or less normally. The hand piece isn’t great but normally works. Foredom hand pieces go right on it when you can afford them

Got the del cheapo going again! It's a little weak for some odd reason but I think it'll see it to the end of the job.
Question, should I open the exhaust outlet up to match the muffler inlet or just let it be ? I marked it with a pencil as you can see in the pic .
