Hi I have a 85 trail boss 250 2 stroke with carb issues. it wont idle at low rpm but does run very good at higher rpms, im not sure if the parts inside are the right ones or not but i have tried a 40 and a 45 pilot jet but still no change if i am reading them correct i have tried a 145 and a 230 main jet the 230 was just an extra. also tried with and without breather box. also how far should the jet needle go into the main jet? should it touch bottom? any info for this would be greatly appreciated as i dont know much about these type of carbs. one more thing it seems the only way to get it to start is with choke on and cover the carb warm or cold no difference.
