Glad to help. I've learned plenty from you.
I'm hoping that you can teach us how to make a 550 has as much power as a 346
That's not to say that it's not already perhaps the best 50cc saw on the market for 99% of users. It's just that I'm a power junky, and I've yet to see one equal of the strongest 346s.

After all the machine work is done I recheck squish clearance.
That's perfect for a saw this size I figure.

I'm really not concerned with a second or two. If we can find a way to make these have enough torque for a heavy handed operator like me to be happy with, then they should be a great saw for anyone. They already have the rpm.......now to make em pull. :msp_thumbup:

I dont know why but these 550s sort of interest me.

opcorn:I want 261 torque and 346 RPMS
Good point brad. Often wonder why so many chase rpms. I like the torque
That squish is nearly as big as the last 365 I measured. There's a whole lotta strato action goin on there, too. So, I wonder if a simple MM and gasket removal works ok, or is the timing too messed up then?
That was after taking .040" out of the squish band.
Ah. SO you can't remove the base on a 550?

You can leave the dark side :msp_tongue:
Im thinking this is great, a 50cc 2nd gen autotune.... But what I need is more like a "590 XP AT" for the hardwoods here in Aus. :hmm3grin2orange:
Was funny, last weekend - in the drizzle, I cut a load and most I did with the stock 576AT, but a big log had me get the mooberized 2095 Jred out..... Now that is loud. It sounded to them like I was just behind them on the hill, not about 1km and round behind the hill and a s-lOad of plantation blue gums away :msp_w00t:

I doubt we'll have anything much........I ain't going in the woods till the ticks die. I might be able to round up a chunk of pine.......but the hardwood is too deep in the land of chiggers and ticks.
Having Lymes changed the way I see the world.
Jon is learning to braze really well. He does a nice job on everything he puts a hand to.
PLEASE STOP NOW!! This is worse than a crafting infomercial for my wife. I love my old 51 Husky you rebuilt and massaged but this saw is on a whole different level. I love having a saw that I can jump off the logging roads with when getting logs ready to pull with the tractor. A light weight saw is awesome. I am getting weak reading about this saw Randy.

Ticks don't come from trees. Google ticks falling out of trees.
