B carburetor problem

Rob NC · Nov 2, 2011

A month ago when the temps were in the 90's the tractor ran perfect. Now that it's about 25 degress cooler tractor needs half choke to run. What the problem folks ?

when you choke a tractor you are cutting of a portion of the air and trying to suck more fuel... you can change the gas filter, check flow to the carburetor, and adjust the jet ( if it has one) or disassemble and clean out the bowl/ jet.

my bn used to be that way real bad, i cleaned and made sure the oil level was full in the air cleaner,retaded the timing by a degree or two and it ran sweet for the last 6years,in the coldest of winters i d start it on choke and leave the choke on about one third and let it warm up for about 5 minutes and it ran great all day from then on

Plenty of gas going to the carb and the oil level is correct in the cup. I guess something is stopped up in the carb. I'll take if off next week and have a look. I don't think it's the timing.

Just looking in the manual the carb has a idling adjusting screw for getting the correct fuel mixture. I'll try this next.
