If you plan on doing chainsaw cylinders I would say nothing less than a 9" throw.

You might just need to move the stone arbor on the motor shaft. The 450 lacks a vertical adjustment in the arm you so have to move the stone arbor when making massive changes to angles.

Some of both, the longer spikes create more moment arm on the mounts so I wouldn't jam them into hardwood like you would something with thick bark.

You can also use some bloc-it heat paste but the damage is far enough away from anything else that I wouldn't bother. I probably weld 10 saws like this a year, most caused by using extremely large WC style AM dogs in Midwest hardwood.

Try an insert first, when that fails I can weld it.

I've welded many like this with only removing the chain brake parts that can be melted and the muffler for access. Everything else is far enough away to not be in danger.

Probably because the MK2 lacks the crank stuffers so the crankcase compression isn't as strong as the MK1. They still don't like more than stock blowdown.

40g 4-1/2 Walter zirconia flap wheel on a corded angle grinder... I got better things to do than waste time sharpening lawn blades.

You don't want to read the chamfer on the port opening numbers, you want when the port roof will open. Some people use a really thin feeler gauge and read right when it's bending into the chamfer. With the exhaust so high you'll want to raise the transfer to support it. Strato saws, with the...

Is that an 046 D chamber with the spark plug insert?

I usually put the transfers at 123° duration on the primary (exhaust side), 122° on the secondary and I keep the entry angle pretty flat. Yes, after 0.040" out of the squish I usually don't touch the opening of the intake.

No crank stuffers! 👎

That hole is right next to a seam which is probably glued so welding is probably not an option as you'll burn the glue out.

I had one AM 395 carb that required some drilling of the low speed circuit to get it to run right. It was always lean at idle no matter the screw setting and therefor didn't accelerate worth a darn. I might have had to lower the pop off pressure too to get it to supply enough fuel at full...

Are you looking to fit a bigger carb in the Dolmar 9000? Because those intake boots are pretty restrictive.
