More problems, exhaust full of petrol

[HxPaul]

Remove complete carb with fuel line connected,preferably with an empty fuel bowl.Turn the fuel on and when the fuel bowl is full the floats should lift and the valve should seat and stop the flow of fuel,if not either the floats are faulty or the float valve is faulty.Gravity fed fuel will not have as much force as blowing through the pipe.

Love the video.

It only fites one way unfortunately - good idea though

well ok that rules that out. Now get a measuring jug and half fill it with petrol, take out your float and submerge it in said jug and petrol and look for air bubbles coming from the float, hold it there for a while and see if it sinks.[/quote]

Thanks will try that. It's new so should be fine but you never know

New is not a guarantee of 'not fooked'

As you'd expect from a new gloat - no bubbles

Just don't understand it

[Snails]

Yes it floats OK too

Only one thing left to try then and if this doesn't work it's clear that your having everyone on then haha.
Take out the float and float valve get a cotton bud in a drill and give the float valve seat a good oll clean out and polish, put some brasso or similar on bud

I aint having you on. I really wish I was.

The float valve and its seat has been replaced.

The only thing I can think to do is buy an entirly new carb see if it works, if does, then the issue is fixed and I have a load of expensive spares I will probably never need - one of which has some unknown issue.

If it does not work I can sell on at a loss, get hammer and smash scooter until I feel better....

Just wish flipping carbs were not so expensive. Totally skint (as always)

The only moderately silver lining I can grasp (call it a zinc lining maybe) is that I could buy say a 28mm carb to use as a test instead of my current 26mm so I could then play around with carb sizes or it might come in handy for a different set up or scooter one day....

the really annoying thing is that I only got this 26mm (off a mate) so I could fit the 25mm I originaly intended to use to my vespa, where as I actually wanted a 24mm for that. If I had a crystal ball I would just bought a 24mm....what with having to switch manifolds and the pain of dropping the engine to do so and the flooding issues its been a complete nightmare..
