carb ?

question: what causes a carb to smoke after the engine has been turned off?
always thought to change metering block gaskets, but they are new...

Keith you maybe leaking gas through the needle and seat. I'd check that first it don't take much if that's not it you may be a little rich on your setup. Hope this helps.

Gotta agree with fuel getting past the needle andseat assembly. I don't
beleive that it is a issue to worry about.

thanks guys, any way to check this, or a remedy, or just replace needle and seat?

Also check the gaskets behind the power valve/blocks
