Looking for some friendly advice before I tear into the carb again. My son's 250 was running well, until the battery died. After it sat for 2-3 weeks, we put a new battery in. Now it turns over well, has gas and spark, but will not start. I just cleaned the carb last year, but that probably is going to be my next move. Any other things to check before I do? Appreciate any help I can get. thanks
