(Dead build) 242 stuffers

[Bjorn]

Golf is trash. Crooked wrist pin bores, shallow circlip notches, uneven skirts. No experience with Api. I would use Farmertec before Golf.

Hello. I havent find any farmertech cylinder, for the 242xp.

Good point. I would go Meteor. $45 from Greece.

Meteors 242xp piston doesnt have windows in the piston. It is a normal 42 piston.

That round fin cylinder is branded and distributed by Brumar out of Italy. Who actually makes it is an unknown, Brumar seems to be a wholesaler who private labels stuff.
Apparently they are decent quality, and porting is comparable to stock from what I have been told by a couple people who have ran them.

The cylinder has arrived. Seems better than i expected.

Sweet thread, can’t wait to see it rip!

Did you reuse the old crankshaft bearings for this build?

Interesting looking cylinder - I wonder why they made it round?

I reused the PTO side because i dont trust noname bearings. The flywheel side is new.

Can you share how you removed the bearing from the crankshaft without damaging it?

Used a normal bearing puller.

Measured squish. It was 19-20 thou. So will hopefully run nicely.

Can you tell me if it’s Nikasil? Or Chrome bore? Thanks

Looks like nikasil. But i have never seen a chrome bore so i could be talking out of my ass

Nikasil typically has a bit of a gold tint to it while chrome is very silver.
Nikasil can also be mildly magnetic.
Then of course there's these newer titanium type plating's, those are outside of my experience.

Okay! Thanks. Yeah I don’t think anyone has made Chrome bore cylinders for about 20 years. If anything it would be a Cast Steel Sleeve if it was a real cheapy

Sealed up the cylinder to the case, mounted handle and tank.

Also did a compression test. Hopefully it gains a few pounds after break-in.

 

[AlexStromberg]

Getting close now. Did a small test without the muffler and it fired up. Looking for muffler atm.

Exciting! Did you get timing numbers off the cylinder?

Sadly no, i dont have any timing wheels or the setup for it. When i port it i will get it.

 

[AlexStromberg]

Choke and gaslinkage mounted. All i need to actually start it now is the muffler.

To test it in the wood i need the later style clutch. A cltuch cover and top cover. Of course looking for the last parts as we speak.
