choke floods cant start

hi hoping to get some good advice.
Uno 1100 weber carb 1992 model

once i use my choke,even on a minimum,it floods so much that i have to remove the plugs to clean.
if i dont clean it and drive it as is,the engine drives underpowered,till i clean the plugs.
its petrol on the plugs,not oil.

should it not have removed the excess petrol while driving for 30 mins?
thanks for suggestions

How old are the spark plugs?
It leads ok?
Rotor arm?
Distributor cap?

Don't clean the plugs with a wire brush .
Wire brush leaves tiny traces of metal on the plug causing bad spark.

If you have been using a wire brush new plugs would be a good idea.
If possible get ngk spark plugs

Re: choke floods cant start

Hi All

it sounds to me like the arm that gives throttle offset it not connected so the choke blocks the flow but doesnt give any throttle opening to compensate.

or the choke butterfly is freely moving when it shouldnt, or the choke throttle unloader arm is not working.

yes new plugs would be good and dont clean with a wire brush, if you use a brake cleaner spray then it evapourates very quickly leaving the plug dry.

Re: choke floods cant start

Or the float chamber is being over filled by the fuel valve not shutting off( assuming carb fed)
