I just put a 72cc 4 speed manual lifan engine in my fiddy. I got it running but it needs a bit of tuning still. The carb i got on it is a 22mm i think, it's probably a little big but ill see if i can get it running good. What kind of plug should i be using with this engine? I'm using the stock one from the fiddy now.

 

use a cr7. dont use the carb the lifan came with. its a piece of **** made for lawnmower engines

 

Is that an NGK? The carb that came with mine is a mikuni. I dont think it's the one that usually comes with the lifan engines, but im not sure.

 

NGK CR7HSA
