ok guys ive head my xt2 sitting for 2 months since 2 weeks ago, seemed to run a wee bit sluggish, then when it got fully warmed up when it idled, bang knocked out, so i reset the needles to factory and it wudnt start, started tuning the low speed a bit leaner til it started, started then knocked out, after a lil tuning i got it runnin, next day was back to square 1, anyways im just wondering if theres anything i can do to try and fix this? also now the pull cord doesnt retrack, im convinced its NOT the spring inside because if i turn the fly wheel to bring the pull cord back in, if you pull the cord a bit enough that it doesnt do a turn over it still retracts

had this problem before i just started it and it went away but, maybe this is a problem that will keep re-appearing

thanks for any help you guys are the best
