need help

so i put in a new engine in my b2200 and ive been driving it for a few days and sometimes when i go to stop itll just die and i start it back up and it sputters alot and running like shit any ideas?

no one knows?

it might be missing on a cylinder, or it might need the carb adjusted/cleaned.

Sounds like a fuel problem.

what kind of fuel problem. like the filter or what i need some ideas

sounds like a loose vacuum line or not connected or, the carb might be leaking air like a bad gasket, or the carb might need ajusting, maybe a rebuild,

it was running fine like 2weeks ago.. then all of a sudden it started running like ass

Does it try and die when you drive or just when you stop?
I'd check the fuel filter and carby for a blockage, to check for vacuum leaks spray WD40 on the hoses and connections on the carb and see if it revs faster, if so that's your leak.
Otherwise check for stuff like bad connections around the coil and dizzy, coil, battery and alt.

i think i found the problem.. im almost positive its the fuel filter.. and im gonna go threw my vacuum lines tomro
