Jet sizes.

[Nova-Boy]

I have a 1.3 carb off an sr (not twin choke) on my 1.2 but am still running on the 1.3 jets. It stin ks of fumes from the exhaust and dont run to well at low revs. Has anyone experimented with jets and found a good one?

P.S. I hgave got a drilled air box! :roll:

perhaps try adjusting the mixture and idle screws.
Also maybe invest in a K&N or RamAir filter. They
should get more air into the mixture to balance it out a bit.
