I replaced the Tilly carb on my 74 tnt 340 f/c with a Mikuni at the end of last season. However,I never ran it long enough to get a good read on the plugs as far as colour/jetting. I know with the old carb (when it ran) the plugs were a nice brown. What size main jet should I be running if the carb is a 30mm round slide. The sled started very easily and seemed to run well, I'm just nervous about a lean setup. (BTW its a single carb)

[green][b] there isnt really a specific size jet. i mean they come with a stock jet for every carb, but i dont know what size it is. you could have the same sled as someone else but they might have a different size jet because of the temperature and altitude their riding in. if your plugs are nice and brown then i'd just stick with the jet you have. if you take the bowl off the carb then it should say the size on the top of the jet.
