Pic of fuel adjust screw on standard carb?

[Guest Anonymous]

My 2002 runs about 8km per liter of fuel (that's about little miles to many gallons). It bellows black smoke... It has a standard single throttle valve single carburator. Can someone please post or mail me a picture of such a carb, showing which screw to use to adjust mixture?

Thanks,

firewall--can't miss it with the air cleaner off. All that black smoke and poor mpg sounds like a rich mixture. Also check float level and the needle valve for proper operation.

Remember, though the mixture screw adjustment only affects mixture at idle. Anything about 2000/2500 rpm is handled by the main jet.

Or is that just a matter of replacing with another type?

If it's blowing smoke when you're running at speed, not just at idle, then turning that screw probably won't do much. You'll want to check out your needle valve and float assembly. If the valve is dirty, it will run rich, and if the float is an old brass model that's cracked, it will run rich because of that. Also make sure you're not pushing gas through because of excess fuel pressure; if you've replaced your fuel pump, put a regulator in line and set it to about 3.5 psi.
