I was wrong on the muffler. That wasn't a hillbilly attempt to stack dimes. He built up a full pad with flux core in order to mount a second deflector. Another head scratcher. He coulda just extended and opened the rear for less noise and same performance. View attachment 86626View attachment 86627
I'm wanting to give Sondre a new muffler for the 395.
I'll take that old one, cut out the Fred Sanford welding, patch it with some sheet and make a milling muffler for mine outta it

If you think the 9010 needs a new one, lets get him one

I should be home early today, then its my turn on the lathe with the other cylinders. I'll post them up good/bad. I'd like to ship out the good mufflers that we've got and the cylinders ASAP to get him back up and running.

@SOS Ridgerider

Please confirm squish on the 6100 and base gasket thickness for me once more.

Does anyone here have a 6100 they would be willing to measure for me?

I'd need gasket thickness, squish, and distance from the base from the band measured with a depth micrometer.

I know this is a long shot. I'd like to get Sondre as close to a bolt on jug as possible.

@paragonbuilder , you may have to cut and sand the band still.

The 5105 jug was cut on a lathe. It was out .007 side to side. I took .008 to clean it up.

Think I figured out how his lathe jugs are off as well. I initially tried to cheat with a 44.7 Ms260 mandrel in this 45mm jug. I wrapped it smoothly in aluminum foil. The jug was out .007 more than it was with a correct mandrel. I believe he's using any old mandrel that's "close enough" on the lathe. I doubt he's making a new one for each saw.

I'm glad you figured that out Al, I was staring at my lathe yesterday trying to figure out how it could be off that much. I was thinking that if the runout on the mandrel was off enough for the base to be out like that, it would be wobbling all over the place, and the cylinder extension would be uneven. So the jug would have to be cockeyed on the mandrel but very little runout to get what you found. A mandrel too small explains it.

He shoulda been a used car salesman. That's where his talent is.
