I have an early model IH 464I - the tractor had been sitting for about 2yrs. before I got it . I got it running and have had rebuild the hydro pump and get the clutch unstuck . The tractor ran fine for a while but started running like crap . We installed new - plugs, points, rotor button, cap, fuel pump , with a inline filter, fuel sensor mounted on the bottom side of the carb.
Now I can go and start the tractor and it will run fine with minimum choke for about 15-20 min. until it warmed up then it will start running like crap spitting , ideally up and down then cuts off . If I let it cool down it will start back up , until it gets warmed up .
If anyone has had issues like this , would like to hear your fix.
Thanks for reading !
 
inline filter would be the first suspect. if it is for a pressure fuel system you will not get enough fuel flow. if you need an inline, go to a napa 3031 or 3032 filter. they are for gravity systems.
 
If what glenster indicates does no good, feel the coil if it is way hot, it is breaking down and needs to be replaced. Jim
 
Your carb isn't right if it still needs any choke after more than a few minutes. If it needs choke to stay running at 15 minutes, then I would start there.

Also perform a compression test.

If carb work, a new coil, and/or another fuel filter doesn't do the job, you might have one or more burned valves.
 
hello guys , thanks for all the replays !!
I have put in a new NAPA filter 3031, replaced the coil , and I have replaced the gas tank , new fuel lines . It will run without the choke ( just a little at first ) , but it is still doing the same thing after it warms up .
