predator carburator

What work can be done to the carburator on a 212cc predator

To accomplish what? You can re-jet if need be, but it's pointless if your mixture is already stoich. If, on the other hand, your engine is modded to the 9's, toss that paperweight and go get a Mikuni or Tillotson or something.

The only need for drilling your jet would be if your engine needs it. Pull out your plug and take a pic of it and post it here. Drilling just for the sake of drilling might just harm your engine more than help

i drilled my pilot and main and it helped alot. i drilled it a little to much i see a little black smoke come out of pipe when idleing but goes away when i rev it not much smoke tho

What piece is the 'pilot' ? Can you describe its shape or configuration & where it fits the carburetor?

 

[predator]

it is the black piece under the idle screw adjustment. it just pops out i used a screwdriver to get it out and i drilled the brass piece at the bottem

[predator]

not 100% sure i think .020 but i wouldnt go over .025

I used a 78 drill bit on the idle jet and lost some low end power i switched back to the stock jet and got my power back

 

[predator]

i drilled mine to .020 and got more topend the stock size is .015 or .014 not 100% sure

yea I think I might have gained some top end but i need the low end since im heavy
