200cc 66.8 rebore, 20mm dellorto carb, ran fine until I went next size up on the piston. Revs fine but no matter how much I've adjusted the carb it will not tick over. Any pointers?

1) Air leak- base; top or either manifold
2) piston upside down
3) blocked jet in carb
4) cable adjustment wrong
5) slide stop vs air screw out of adjustment
6) tight top end- bore to piston clearance?
7) piston wrong height on inlet side??
8) new barrel? port timings way out?

It's not piston upside down or gaskets. Never moved adjustable nipple for throttle cable to carb. Not new barrel. Gonna try other options though cheers .
