    Leak at intake manifold?

    If I recall there is (or should be!) An O ring on the little cast manifold? Maybe it's missing, perished, or the mating faces have corrosion on?

    Ah, I'm thinking of a 90cc. 65 has a weird looking carb! Either way, symptom seems like an air leak on intake.

    Is your float level correct? Is the throttle cable seated correctly? Is the choke on? As a_morti says check for air leak. Spray some wd40 around the carb and if the revs change you have an air leak somewhere

    Have you trapped the throttle cable when you reassembled it? And is fuel getting through at a normal rate?

    Whereabouts in the country are you? Somebody nearby might be able to have a look at it for you.

    Sounds like it's revving its titsoff, emptying the float bowl and then taking a while for the float bowl to refill.

    Yes it started OK so cleaned the carb after doing that and putting it back togather it runs for a short time and cuts out but revs are to high from high to higher then calms down and surges again will check

    It will only run with choak on and I'm in Leicester where there is a honda dealer

    Chokes operate by providing more fuel and less air so it would seem you need to clean the carb again

    Starts now with choke off but dose not say running for more than 10 seconds and cuts out fuel flow is OK put in a new fuel filter and no cables are trapped just checking contacts at moment

    Obviously there is rust in the tank and rust will also mean water. Empty the tank and clean it out new fuel new fuel filter.
