Runs rich and then becomes lean

Where did you get it from?

 

[Hell on Wheels]

An eBay listing. From China directly. They renewed the porting but welded the head shut.

What? They welded the head to the jug?

 

[Hell on Wheels]

It's only attached by the M5 bolts at the bottom. The copper coil is because there aren't enough vanes to cool the thing down.

 

[Jag]

holy f***. You have a gasket leak somewhere

And is that 49cc’s

 

[Hell on Wheels]

Nope. 66cc. 40mm fm80 crank. Type b piston. Yah, it looks ugly. Saw it dripping from the intake so I am taking it apart and it's puddling with gas because it's upside down and I have no space to install it right. I already cracked my frame once from this engine so no more frame mods until I need to reinforce

Can you send some more pics of your engine? Like I take and all that

Looks like the Chinese made their own design even worse
