Re: Ok, I give up. How do you start these things?!
I recently purchased a ZoomBicycles slant head. the only real complaint I had was that whatever was used to secure the screws on the gear cover was too strong. easily stripped the soft screws used to secure it. had to drill through the three heads to solve this problem.
It has seemed to me that these kits (not just zb) will sputter to life just before you're ready to give up. just when you think you've been had, buuuurrpppp, putputput...
can you hear the piston turning over when you release the clutch?
maybe try half choke?
