After finding my GP carb will no longer fit my VCH without getting rid of the Velocity stack I picked up a cheap 389/1 from ebay jetted for AJS single.
As the cover was a dodgy I set it up on a bit of timber bolted to my lathe faceplate with 3 cheesehead screws located to grip the cover holes and held it against hard up with a tailpost live centre to skim it up.
This solved the leaking cover but now the float needle and seat does not seal, I have removed the washer from under the seat fitting so it goes further into the float chamber and replaced the float needle (plastic one) float is brass.
It appears that to get a good seal the needle needs to be longer or the float contact point raised (most earlier floats have a tab that can be bent to suit but it appears this tab is soldered down so not adjustable.)
Are there longer needles or floats with adjustable tabs that can be used to solve this problem, or should I try and build up the tab with solder or something?
