I can probably fix that motor.

My right angle handpiece will work with the Dremel Fortiflex motor as it's a key drive cable just like the Foredom and all the imports like the ones from Harbor Freight or Vevor. I'd recommend the Vevor SR for a cheap import motor as HF discontinued their hanging flex shaft motor.

Just up the road is Markham Vineyards, one of my favorite main stream wineries in Napa. Also, Castello di Amorosa is just a neat place to see.

Thanks, I use 3/8" diamond ball in a #28 handpiece. https://www.mcmaster.com/4490A49/

Yeah, I can sell one. I'll have to check if they are the thin top cover clips or the later wider clips that came out with the HD filter system. If they are the thin ones, then you need a thin style cylinder cover.

I took 0.030" from the squish band when I did this 800P, then I had to raise the transfers 0.125" to get the transfer duration I wanted. The numbers I landed on in duration are 158 ex, 119 tr, 156 in and I thinned the throttle shafts shafts and opened up the venturi some on the carb.

I have some NOS low top air filter covers.

394 has a cylinder extension that goes into the case so sanding on a pane of glass wont be easy. Those numbers are good for a tamer ported saw. I'd bump up the ex to 100.

I just tig weld in an extension into the OEM rod.

Looks like they used aluminum filler instead of magnesium.

I just put modern 660 bar studs in it and then counterbored the clutch cover to fit over them.

Wasn't that the JMS disaster that had a bar stud pulled out and it was cracked almost through the bar pad? If so I'm glad I could get it fixed up!

You wont see much of a gain, it's more for the modern features like fast idle with the choke lever and better idle from the nozzle style carb. You have to create a longer throttle and choke linkage, and it moves the air filter back a little bit so it's not a direct bolt on. The 3120 carb is a...

If you do catch it on fire snuff it out with the argon from your torch... don't try to blow it out like I usually try first!

No need to tear it all the way down for that area, it's far away from any gaskets and seals that could be damaged from heat. Leave the bar studs in, they are a great place to attach your ground clamp to. I usually clean them with degreaser and bead blast the area if I can. Keep a dedicated...
