Re my post of 29/12/22-
I have been persevering with this ‘brand new carb’ for my 3HW. I have sent it back to ‘Burlens Fuel Systems’ twice and the leak at least when the fuel taps are just turned on is now cured. But now I have black smoke blowing from the exhaust when giving the bike any throttle. It looks like I will be having to check the carb has the correct jets, needle setting etc. Not something that I would of expected from a new carb supplied specifically for a WD3HW. Ron P was right when he said he had to check the internals of a new carb he fitted, but my opinion is that when you lay out £460 for a carb it should be at least assembled correctly and with the correct jets, needle setting etc. I will post progress on this ‘NEW’ carb as the saga continues.
The maintenance book states NIL clearance on the valves, we have set them at 2 thou (don’t like nil clearances)
Opion especially from Ron P please..?
Rings and bore are okay.
Any other ideas of the cause of black smoke..?
