Hi fred, I'll be around this weekend too, i don't have a flat tire, i was just wondering how to do it since i had one before and had to pay someone to do it, which is bad. but i could really use help with figuring out why it won't run properly, i guess cleaning out the fuel lines or something. any time this weekend is good for me except sunday night. I really don't think i should go at it myself becuase i have no idea what im doing. call me or email me if you have time! thanks!
