When my tractor sit ls gor awhile i can go
start it and it pops right off with out even
choking it... it will run good and idle for
around 3 to 5 minutes then it kills and i
need to choke it to start and it will only
run on full choke. Then it wont even run
with the choke after about a minute. Il have
to let it sit for a long while before trying
ahain and it will usually pop right off
again after sitting.. i took the carb off
and sprayed cleaner in it but im unfamiliar
with taking it apart. I also drained the gas
and filled up with fresh gas. Still doing
the same thing
 
May have the carb brass inlet seat partially blocked if the flow to the carb is OK. Neighbor's IH 656 did the same thing last month, carb taken apart and found the small hole in the needle-seat unit almost plugged. Ran fine after cleaning.
