Anyone got a good way to get stuck jets out of a Farmall 100 Zenith carb? Soaked for week in carb cleaner(Gunk),soaked for week in PB Blaster,won't budge. Will heat damage carb? Thanks

Is this the main jet accessible from the back of the carb :?: If so make yourself a screwdriver that fits the slot pretty tight the full width across. If it's the idle circuit jet grind a small screwdriver for the same fit.

Donny I have tried good fitting screw drivers with a wrench on square part of driver ,won't budge. I was trying to help a friend out since I have rebuilt my Cub's carb and my uncle's Cub carb,with no trouble. These are really tight!

I guess I'd try soaking them with KROIL for a day or so.

Before going the ole heat route,---keep in mind that the carb body is luni!---heat can warp them pretty easy!---My question is---WHY are you taking them out?---there is nothing to be gained by removing them!----just soak them with good strong carb cleaner, poke a wire thru them, then blow them out with 175 psi air blow gun!---works every time and nothing gets brok off! thanks; sonny

My friend kind of messed up the jets before I got the carb.I'm not so sure they will work properly now,but I might give it a try anyway. Thanks

OOOOPPPPSSS!!!!---yea! now I see a need for removal!---I dont think easy outs will do the job!---might have to use hand drill and VERY carefully drill part of them out,--then get in there with a sharp pointed pic and clean the threads out---a little heat MIGHT work, but dont overdo it!!! LOL!!!----Put atf/diesel mix around the jets then heat that a bit ---yea it will burn, but it also gets in under the threads ! do this several times and keep trying to turn/wiggle them a little.
sometimes this will loosen them up! thanks; sonny
