Fuel problems
Iainhugh:
Cheers for the advise Scottly. I'll just have to take carb off and have a look
I'm currently trying to fix a grabbing front brake. Disc skimmed and new pads getting fitted over weekend ,
Regarding the seat what am I looking for. The carb was cleaned out and then a new valve fitted.
I'll get it off and inspect it , I'll post my findings
Thanks again

Had the carb off and re checked everything . Put it back on and it's still pouring out.
Floats are fine . The float seat itself has no visual damage , but I remember the old valve I took out had a ring all the way round the rubber tip. So maybe I need to change the seat itself or you mention a build up of varnish. Is there any special ways to clean it. The carb has already been cleaned out when I did the jets.

is the float pin engaged in the slot on the float when you reassemble your carb very easy for it to become disengaged when you are putting it back togeather just a thought a long shot but worth checking
Iainhugh:
Yeah the pin is in fine. I did think of this since the carb is getting moved about to refit. I had bowl on had carb on side shaked about. Pin isn't coming out so it can't be that .. I'm leaning towards valve seat. Where the bottom of the seat tapers down to the hole the is a ring all the way round the hole. ??
The same mark I saw on the old valve ? Has any one changed one of these? Is it a case of destroy it to get it out. The top of it sits flush with inside of carb ,

Is the ring a dark color, or clean brass? It might be rubber transferred from the old needle? You might try cotton swabs soaked in carb cleaner to polish the sealing surface in the seat.
