Hi all,got a problem with my 99 610tc, if you blip the throttle lightly from idle it splutters which also makes it awkward to set off at times . There are no problems with starting hot or cold ,although it never needs the choke to start, im thinking its a carb problem as ive changed everything on the electrics side except the wireing loom. It smells like its running rich and it dose chuck out black smoke if you rev it hard. All the jets are oe the main jet is a 170 , i believe from the factory it was a 175 , im not to clued up on jetting and was wandering if anyone thinks it needs smaller or bigger jets , or anything im missing here,oh and i have tried adjusting the mixture in every position possible but it dosent make the splutter worse or better, anyine any ideas please
