I would suggest checking that your carburettor accelerator pump is working properly (engine off-choke off -look down carby and operate throttle rod - you should get a good sqirt of gas from each of the pump outlets). If your accelerator pump is not working your engine mixture will be lean on rapid throttle butterfly opening and denotation may occur momentarily. That's my theory and worth a try. Peter Toet
