Hi I recently purchased a YB 100 1987. Seems to use alot pf petrol, about 70 miles to a tank, uses very little 2 stroke. I have checked the air filter and it is very clean and a little oily, no sign of any splits around the intake. Checked the plug and is a bit black and sooty indicating a rich mixture. Thinking about investigating the carb, it looks like the cover has been removed many times in the past. Would like to have some advice on the carb, how do you know when it is worn, is it worth replacing, can you get reconditioned carbs, are the carb kits any good. In short I know very little about carburetters and I'm looking for help. Many Thanks Spike22
