Just had the tickler jam open. depressing it a couple of times helped but it continued leaking. so turned the fuel tap off.
I've just taken the bowl off and there's no evidence of dirt in the bowl, or valve seat. Viton tipped needle looks fine. Old non stay-up Float intact with no fuel inside.
So I'm guessing its just the ticker itself. Could I guess be gunk I can't see in the tickler seat, but wingling hasn't produced any.
So any advice on preventing the tickler sticking ?
Just a guess but it could be the tickler is bent.
Spray carb cleaner from a decent aerosol a few times from underneath.
Does it stick when you push it all the way down? I had a similar problem a few years ago - learnt not to depress the tickler all the way down. It only needs a small movement to push the float down a little to open the needle valve ( or it did on mine!). It was always customary practice to keep pushing the tickler down in rapid succession years ago when I stated riding. Apparantly this is not good practice!
Another common problem is the little brass collar that goes on after the float is missing, (was on mine) if this is missing the float can move sideways and does not shut the valve so petrol keeps on coming.
