What’s a good jetting starting point for a 472 4 mil super cub that’s drag ported with sb shearers in frames using 39 mm pwk cel needles and a 4.5 slide ?

It’s non oxygenated

I got a chance to buy a barrel of vp late model plus fuel for $5 a gallon. Anyone have any input on using this stuff ? Good bad ? I believe it’s 116 octane. Description says for larger engines so I’m a lil leery about trying it. I have a 4 mill cub been running c12 for many years

Still got it?

Still available

i want to start drainging my carb bowls after very use because im running race gas with hp2 oil and it says on the c12 gas do not keep in carb and it turns to syrup quickly.i have kehin pwk carbs, is there a kit you can buy for this without drilling or tapping your bowls? i thought about the snowmobile carbs and they have a factory water trap out the bottom of the carb where the nut is but not sure if it will screw in any one have n e ideas or show pics what u used

im looking for a set of shears small bore out of frame same side WITH silenecers for a 421 cub n e one have some or know where to get them

doesntleak bad and not all the time, my pipes r not blue and plugs look good

i just got a cheetah motor and the over flow is just routed down the frame no overflow bottle with the new motor it keeps pissing out the hose when i ride it spraying all over. the old motor never did this.woud there be a reason y it is doing this with the new motor

its just annoying it wants to die if im not on the gas after its hot

i have small bore shears inframes 35mm keihns boss intake clean up port job 4 degrees tming advance

they just made one at bundy hill in se michigan by devils lake its only 350 ft and that includes slwing distance so it kinda sucks

got a 4 mill cub 35mm carbs idles when i first start it up but wont idle at all after its hot whats up

it has heavy springs in it i dont think its the cable bc i just changed the motor out and the old motor didnt do it. would deep grooves in the basket cuse it to shift hard too?
