hello, i got my drifter 440 at the beginning of last year. it ran great for a while then i noticed it started to bog, i think its a over heating isue. what happens is it runs great for about 20 minutes and then it just boggs. if i let it sit for a while it will run good agian and then bog again. ive cleaned the carb, fuel pump, replaced fuel lines put new spark plugs in it but they keep coming out burned on the left and fouled on the right. if anybody knows what my problem is i would love some help.
thanks.
