Hit & Miss Model from Banggood

Hi Team,
I dismantled most of my engine so as to tap the mounting bolt threads larger diameter and deeper in the base.
I also found one of the main bearing housing bolts was stripped--I tapped them deeper too and fitted longer bolts--I machined an alloy plate to go under the engine for the flywheels to clear the wooden board I mounted the unit to.

Anyway I retimed it as any other automatic inlet valve engine I ever worked on in nearly 40 years of playing with these old jiggers--exhaust valve to close at or as near to TDC as the gearing and valve lash settings will allow.

Thanks for the alloy plug tip as my radial engines had these--just trying to think of something as a fix for anyone without the luxury of owning a lathe like myself.

I also found my flywheel appeared to be wobbly, by re-tightening the pair of opposing grub screws, that affix the flywheels to the crank, I got it to run true with little difficulty.

Cheers,
Eddie B.

Hi Does any one know what size o rings to get that fit on the piston? I thought it took 22x1mm but the o ring is too big diameter for the piston.

Piston o-rings are 22mm x 1mm. Oringsandmore.com

Oops!! 20mm x 1mm. That's what happens when I try to go off memory.
On the banggood site it says 22x1 mm but I guess the newer water cooled engines take a different size.

Hello all
I just had a gander at the Banggood website and they have some interesting stuff. I showed it to Mrs Scotty and apparently she already shops there.
She's never bought me anything from there. :cry:
Cheers Scott
