*????*Hi All. I have recently converted my A10 plunger golden flash from monobloc to concentric, it seems to run o.k. but sometimes when it's ticking over it will just give a spit back, then stop, now, the question is do I need to change the jetting? I have heard some say that it should be reduced, if so what size main jet should I fit to try this out? also should have to drop or raise the needle?
Many thanks in advance.
