I took my carb apart this morning to find out that the jet is broken off ( no brass in the casting, looks like it has been working loose for a long time, threads stripped), i wondering where i can find a replacement. I believe a good cleaning and a new jet, along with some new gaskets will due justice to this carb, since it ran really well before, any comments and suggestions would be appreciated
 
It appears to be available at case IH

idle metering (used with carburetor, 363741R91) (B only)

Product No: 49798D72
 
Great info, found online, looked before but couldnt find, wasnt using the site map the right way. Ordered parts today, will let you know how it turns out, THANKS JIM!!!!!!!!
 
Think 49798D75 was used in a gasoline carburetor if that's what you have, but the 49798D72 will probably do.
 
That's a confusing thing they never corrected about the parts. If its like it used to be they show the 75 jet for 363741R92 distillate kerosene and a 72 for a 363741R91 D&K carburetor. doesn't say which one is for a 361525R92 carburetor but in a parts book the 75 is listed in the gas Cullum.
Carburetor specifications show a 72 for 363741R91 and a 75 for 363741R92 and 93 and 361525R91 or 92.
Have checked enough sizes in the carburetors to notice the 72 didn't sound original to a 300 or 350 gas carburetor.
361525 is the gasoline carburetor.
 
Notice gas carburetor 361525R92 on the line above paper. Idle jet drill size #75. That's the size IH used on the end of the part numbers.
# 75 = .021 hole. # 72 = .025 hole. Depending on the engine and fuel type the 72 may work fine, but if you have a gas carburetor the 75 came in it.
