Blocked Carb?
Turbo Mini Forums

Went to start the car again after about 3 months of being stood still, it cranks over ok but no fuel is getting to the carb, looking at the little fuel filter I have after the pump and between the carb there is fuel at the bottom but none moving through.

Take the hose off at the carb and crank it and fuel spurts out as the the little fuel flows through the filter fine. So im thinking that when its all connected theres a blockage in the carb? As when i conect it back up again the fuel doesnt pass through again.

Took the dashpot off and theres some fuel at the bottom, buts it looks abit greeny for some reason! Im thinking where its been on the drive at an angle all the crap in the carb has gathered and blocked something?

Im pretty sure something in the carb is blocked it cant be anything else, so what bit could be blocked? Im taking it off tomorrow to take it apart, where should i look for any build of shit and gunge?

Thanks!

Take off the float chamber cover and check the needle valve isnt blocked..

When you take the pipe off the carb and run the pump does it glow properly? as it should piss out with the pump running.

needle float valve sticking

yes rich, inspect the needle valve these unscrew out its, made of brass

clean it up with some turps or parafin
make sure theres no debris in there and its not sticking

if its fooked i think maybe minispares sell them, but i could be wrong ?
job done

Got it going and it runs well now!

Took the carb apart only to find that it was really quite clean, but stripped it down and checked the needle valve over etc and put it back on the car and it started first time! Awsome!

Set it up roughly so it idles ok now, but ive got a feeling that the mixture screw is all the way in rich, and it just about idles at a decent speed and pics up quite nicely, leaning it off a little bit makes it pop and fart out of the carb but then picks up after.


Thanks again for the help!!
