I got a 22mm mikuni carb kit from nr and i am having some problems with it. i tried the 130 jet for clone but it ran like poop. then i tried the stock jet that i drilled smaller than the 130 and it ran a bit better but then it started leaking out the bottom of the float bowl and the over flow tube/vent. that being said i replaced it with my old bored clone carb and it ran waaayyyy better bottom end and topend. help please!
You have to tune the carb to your engine. What is your set up. Do you have a pipe? what else?
When you took off the float bowl did you take out the float assy? If so did you put the float back together right? There is a spring that holds the float to the fuel cut off plunger, if its backward it can bind and cause the bowl to over flow.
A #130 is a bit rich for most applications I run a #125 with a 17.5 pilot with a cam, rod, flat top piston, springs, billet flywheel, exhaust, and 8 deg advanced.
These carbs are super sensitive to dirt, you must run a fuel filter to make sure no crud will get into the float and jets.
