I've got AM cases on numerous saws (mostly 660s) and have never had a failure, and I've built some that were used professionally for years. In fact, the local firewood guy said the ported (Cross Jug) Asian MS660 was their favorite saw. My Doc Al Hybrid also has an AM case and tank holder, and...

Wow, great price for what it has. If I did not already have 17 running saws, including a great running 10mm 044 (that I purchased new), I would take it off your hands!

My friend Harold and I also revived 2 Stihl Pro saws today. Harold installed a spark plug insert in a MS461 that had stripped, and I did the rest of the work to get it running. Harold has done a ton of work on Motorcycles, but not so much on chainsaws, so I walked him through cleaning the...

I have always used my mechanical Craftsman calipers ... never needs a battery!

I know that OEM plating is generally harder than AM plating, but I would practice on an AM cylinder before ruining an OEM cylinder. That was a big part of the reason I played with AM saws ... also to learn a little about porting. When I do some porting (I'm a real amateur) I look at it like...

My brother and I were unable to start his Asian MS660 on Friday, so today I took a look at it. Checked the air filter and plug, both looked OK, so I primed the carb a bit and she fired but would not run - must be a fuel problem. Replaced the fuel filter, and that and the fuel line both looked...

Al, I remember you did some incredible work on my Hybrid, and I used it yesterday to drop this large Sugar Maple stem. The 28" bar was just the right length, and I really appreciate the incredible power to weight of this saw. It is a concoction of an AM case and tank holder (yea, I wanted all...

See how it runs, but some of my 660s (w/o Husky pistons) seemed to like the Exhaust at 96-98 and the intake at 82-83. I was told by someone (who built a strong running 660 for someone I knew) that the 660s like different #s than 440 or 460s because of the longer stroke. One of the saws I did...

Should be loud, but it will be interesting to see how much it improves cut times. On some 660s sometimes too much open muffler reduces the torque (but not on others, all depends on the saw).

IIRC Doc Al built my hybrid after this, and it is a torque monster. Asian case and tank holder, OEM 044 12mm crank, ported 046-D jug and Husky piston. Pulls a 28" full comp chain in hardwood like nothing! I think my hybrid, and my Doc Al ported MS360 are my two most impressive power to weight...

I see my post above is from 5 years ago. The guy recently sent me a video of the 440 BB and it is still running well on Saber at 40:1. He heats by wood, and that is his primary saw.

I always flushed them with the kits before they were assembled. If your saw came assembled, and you have already run it, I would not worry about it. I've noticed the assembled saws (they all used to be kits) seem to have less problems than the kits did. Quality control must have improved...

A few things: I have not had any problems due to removing of screens, but then again, I don't generally have large openings in my exhaust. If Joe already enlarged the opening, removing the screen may not be beneficial. I would discuss this with him. Just because opening a muffler adds power...

Not the best start to spring I have ever had, but I'm surviving. Had food poisoning a few weeks ago, and doing PT for back/hip issues, but I'm surviving. Starting to get back into a normal pace. Our dog Lucy is 17 now, doing OK but is extra work. Such is life. Grandkids are all doing well...

If you would like to unload some of those worthless notes, just send them up here, but sorry, I don't have a 390 XP cylinder. Hope you, the family, the business and the farm are all doing well!
