mixture set up

[jimmy_b]

hello ppl,

whats a basic rule of thumb to set up the mixture on the carb?
i have just fitted a new carb and it wont idle smooth and stalls. im guessing its the mixture. i can do it properly at work on the emisions tester but need to get it there first.

cheers

Think the mixture screw should be turned out about 2.5 turns.if you have an afr gauge installed, 13.9 gives you about 1.5 % on your emissions. Might have to mess with your idle screw too dude.

afr gauge is something i havent yet got. the carb is set to run safe at 20psi but i'll leave it at 14psi untill ive got the gauge.

so basic rule is full in and out 2.5turns t set it up roughly.

ive been playing with the idle but its hunting too much to set it up

When I set mine up I tinkered with both the idle and mixture screw till I reached happy medium. I ended up with an idle of around 900 rpm

If it's still a bit lumpy or stalling even after you adjusted the mixture, pull the idle jet out (big brass screw) blow it out and fire her up.

You might need to do that a few times :)

IF the prob is still there, check for air leaks around the carb :D

AND leave the boost set at 20psi all the time...14psi is for girls :cooter:
