Remember what we talked about last time...

044 crank and Wright C-50 piston and rings?

044 crank and Wright C-50 piston and rings?

Yes, how did you know?

 

[Duane(Pa)]

I was in jr. high. Huge debate at lunch between 14 year olds... Mac 10-10, hard nose or Homie SXL auto, sprocket tip. Remember it like yesterday. Yep, I'm that old! Geezer story lol

There goes the world...

 

[Lightning Performance]

There goes the world...

Or the budget

I actually put a Homelite 540 thin-ring piston and rings in a ported 385 once. I had a local machinist ream the wrist pin bosses out to 13mm.

It made a pretty good runner.

Not really an issue. I don’t give Kev a budget...

I can identify with you Duane! These young fellas don't know that was about our only choices!

 

[Al Smith]

There really isn't much you can do with a 10 series .Find the muffler with a curved bottom and pull the baffles . Buy a good set of ear plugs .

Buy a good set of ear plugs .

+visit your dentist to get the loctite on your fillings re-upped.

Welded popup Kevin?

Where is your squish?

Are slugs still available?

Good to see a damn build thread here again.

 

[drf256]

One on eBay, but if bore bigger than a standard 10-10, not sure what you’d need.

@heimannm

Mark, do the other mentioned model’s pistons fit the bore?

 

[Al Smith]

They are a funny animal .Some would shake the teeth right out of your head and some were rather smooth .I could never figure it out .
I've got several,a few righties a few lefties and one of the last ever made .That one was given to me by a trimmer who I doubt put an hour of run time on it and came with a McCulloch branded chain I don't think was ever filed .It's a shelf queen .

 

[Steve]

McCulloch was pretty good about not leaving any room on the plate. He made them pretty well maxed out from the factory. Get yourself into an iron bore 10 series, they have a pretty interesting swept transfers. 6 of them!

 

[Al Smith]

If memory serves the iron bores have a full skirt windowed piston .The transfers in effect the way they are timed create an interesting sweep effect .Taking all that into account the 10 series was pretty advanced thinking even with the bearings in the piston which was just plain stupid .That's the weak link .

The carb is HUGE on these things for the cc’s

The super 6-10 used a later thin steel ring non- full skirt piston as well as the early rhs 7-10 with iron bore. I believe the full skirt was used on the 54cc engines for ballance. both engines used the same crankshaft.

Good thing - it'll take him a while to get the 066 cylinder and piston in there.

 

[P.M.P.]

Hands got oily and dirty real quick, so I didn’t get more pics of the disassembly

Not a pulling tractor, more like a Farmall Cub lol.

My Cub is a tractor dammit...

Send it out west. CJSaws

I think he changed the name and now accepting new clients for 2020...

 

[heimannm]

All of the 57 cc models (PM55, 555, 570, 10-10S) used the same 89783 piston, 1.812" bore. Interesting to see that the PN for the rings changed, 89436 for some and 92517 for others???
