After watching the video, I think the problem could be normal tune-up adjustment of the carb OR it cou

ld be other carburetor problem. such as er loose internal part

So start with the most basic setting - inspect the float level, then do the tune-up carburetor adjustments. Too fast an idle can cause engine to run-on and not stop immediately

What does "buff" sound mean?

Tune-up includes carburetor adjustments.

Hi Guys

I got a problem with my b310,since few weeks ago it used to overflow the
carburetor time to time, and then i removed the carb and found that main jet was
detached from the thread and fallen down the carb,and then i bought a same size jet
and installed it back did not go for a big tune up since it is same size,
but now car is giving trouble it start once but stumbple and die till the engine is warmed up
when the engine is warmed it doesn't die but stumble on sudden acceleration,but can accelerate
smoothly, and also there is sudden buff sound in higher rpm too, and also car doesn't die
after key off , it takes 2 more seconds with buff sound is it carburation problem or just a tuneup is enough ?
