[QUOTE="johncrispin, post: 34011, member: 53"] Until last week my Comet wore a rather knackered Monobloc on it and I could wiggle the slide in the chamber bore with my finger. The popping and banging was getting embarrassing . A pal has loaned me the correct 229 carb, recently refurbed and it is running now as sweet as the proverbial nut. BTW the exhaust nut was a non standard o/size .A new o/size bronze nut was made by a very nice man I know in Cornwall, but I dare not insert the gasket which butts up against the flange in the port. (I found it very difficult to swage the flange on the ss pipe so too much radius) and not wanting to put the otherwise good thread at risk simply assembled with copious quantities of silicon gasket. If ever this was prone to leaking it would be now but seems good. I have placed an ad for someones unwanted 229 carb body in for MPH wanted ads (I have a float chamber) The new ones are simply too expensive for me. Happy to swap for anything useful also. Hope you sort it soon [/QUOTE]
