unrestricted stock carbie

[zingshoen]

who has made some carbie modifications? i m trying to find the optimum setup for a totally unrestricted stock carbie.

history: after changing header pipe and muffler and replacing the airfilter setup with a podfilter stuck onto the air inlet pipe, i ve been using a 140 main jet, the needle in the 3rd groove from below. that worked okay, but i needed the choke on halfway for about 5 ks.

now: i m changing to a podfilter and i ve shortened the intake betwen carbie and cylinder so that i can fit a podfilter angles at 30 degrees.
i ve changed the needle clip to slot 2 from below, but i d like to hear from someone who has experimented with (1) bigger needle jets. the standard is 32;
(2) larger main jets, such as 145 and 150.

also: where can i get bigger needle jets from, such as 36 and 40? what s the zong carbie a copy of? it says "japan" on the side...
