Powerland 420cc Carb

[aham2003]

Putting a intake and header (and removing governor) on a powerland 420 this weekend. Instead of jetting the factory carb, is there a carb I can buy that is ready to go out of the box? I dont know a lot about these Mikuni slide carbs that I keep seeing. I would like to have something that I can just bolt right up and not have to mess with jets or anything.

Thanks in advance.

Any aftermarket carb, or even stock carb, will require re-jetting.
On my Powerland 420, I am using an OKO 32mm. It seems to like 30 -32 pilot jet.
I haven't had a chance to mess around with the main jet. I have the needle clip in the middle position, but haven't tuned midrange either. I cap off the powerjet circuit with vacuum caps.

Not likely to happen.

You would be better off jetting the stock carb as there are fewer adjustments to make than with a slide-type bike carb and you already have a good starting point.

Maybe this unit will do the trick.

Nice. I will order it and see how she runs. Thanks.
