Here is a good article on how to tune your carb. Maybe this will help ya out.

If your current configuration has been installed for awhile, check the plugs. If they're black and sooty chances are you're too rich. A light brown,glassy deposit means you're too lean and running hot. White,yellow,tan or rusty brown deposit indicates balanced combustion. Also, run your finger inside the pipes. Heavy black soot...too rich. A light soot on your finger means you're about right.

 

Lean running symptoms

[ol]
[*]► Bike hesitates when throttle is increased

[*]► Bike runs jerky or surges at steady throttle openings

[*]► Engine detonates, (knocks) when accelerating

[*]► Engine spits back or coughs through intake system

[*]► Exhaust pipe deposits are light gray in color

[*]► Bike runs poorly when cold – engine runs better as it warms up to operating temperature

[*]► Spark plug color is white

[*]► Fuel consumption is abnormally low
[/ol]

Rich running symptoms

[ol]
[*]► Engine blubbers when throttle is increased

[*]► Bike emits black exhaust smoke, (a little black exhaust smoke is normal when accelerating hard or operating engine when cold)

[*]► Exhaust pipe deposits are dark, or black in color

[*]► Engine blubbers at steady throttle

[*]► Engine fouls spark plugs

[*]► Bike runs well when cold – engine runs worse as it warms up to operating temperature

[*]► Spark plug color is black

[*]► Fuel consumption is abnormally high
[/ol]

 

anyone know where if they have a link to adjusting the old bendix carbs? Thanks

Duh, I didn't see the "download" in the first post. Guess you don't need any 411 on carb tuning.
