i just rebuilt the carb, and sprayed carb cleaner around the base and all the lines. here is the whole story. when i first start it up in the morning, it runs fine. on the way to work, after i get on the highway, when i finally get it up to 60 or 65 mph, it starts cutting out a little and chugging. when i get off the highway, it runs VERY erratic. it will idle from about 250 rpm to about 1800 back and forth for a little bit then finally die if i dont do anything. if i pump the gas just once and not a lot, (just tap it good)it will idle about 850 or 900 but not steady at all. and the exhaust pops and gurgles something fierce. i replaced the dist. cap, rotor, plugs and wires. when i took off the cap, the carbon plug was gone and the inside was blown out around the cap. wtf?

. i am trying to fix it but nothin is workin. the tail pipes sounds like it is sucking and blowing which leads me to a head job. i dont know but im gonna have another beer and drown myself in buds suds.
