Late model 4020 gas carb

770puller · Apr 7, 2015

Looking for an original carb off a late model 4020 with the 362" engine or if someone could tell me if the ones on the 303"
gas in the early 4020 and 6600 combines were the same thanks!

Late 4020's used either Marvel-Schebler Or Zenith carbs, both would have been original equip. 303 gas [carbs are dif.] was Dubuque built, used in 6600 & older combines, 341 gas used in 4010 ,early 4020. & early 105 comb. same carb,.. 362 gas used in late 105 & 7700 combines , All were Zenith carb,

I have a Zenith off a 1970 4020 with 362 gas.. Its been rebuilt. I also have the huge carb off the 362 gas out of a 7700 combine. That is a Zenith as well.

Yes; 105's after serial # 19000, Which I think were just the '69' model yr's.....
