can anybody tell me why carb on cylinder three dosent flutter up with the others dosnt move much at all.. does it just need a adj. pretty simple question i hope.

If you mean the slide doesn't move as you blip the throttle, this is bad - you're basically running on 3 cyls. It probably means there is a vacuum leak to that slide, and it isn't being drawn up.

Strip the upper part of that carb - look for obstructions, plugged passages, gunge in the slide track / on the slide, missing o-ring at the top of the body, dead mouse holding the slide shut. Worst case is a torn diaphragm - $$!!

Just checked top carb had a slice in the rubber bladder part would that be my problem

"Well, that's your problem right there!" Crap..


There was a recent thread where a fellow repaired a SMALL hole in a slide diaphragm, take a look for it. There is a product my wife found recently called 'Liquid Electrical Tape', a paint-on rubber coating.

Try it - you can't be worse off than you are now.

Hi,
an actor friend of mine repaired his carb diaphragm with a tiny piece of facial tissue and make up artist latex rubber (the stuff they make up false scars etc with ), knowing him since it worked i doubt he replaced the diaphragm saved the money for his favourite single malt <BG>
