Good Evening,
I am completely lost here and would appreciate any help!
I have an Allis WD45 that is sporting the Marvel Shebler TSX 464 Carburetor. Here is how this all started.
I went and hooked up my snow blower and parked the tractor in the yard waiting for the snow to come. Nothing until after Christmas. When I went to fire the old girl up she ran fine and was blowing snow for about 10 feet worth and started running like crap. So i didn't have the tractor stuck in a weird area blocking the driveway, I parked it off to the side. I had a friend that said he knew a lot about carbs. He pulled it a part and we found gas was being retained in the float so he was pretty confident that was the problem. I ordered a new float and needle / seat. He put it together and "cleaned it" (i probably should have just put a new kit in it right away. One is on order right now) and then dropped it off at the house when i was at work.
When I got home, I reinstalled it and the tractor did run for a little while and then died. I have not been able to run it every since. The one part that i notice was happening was that gas would come out of the air intake of the carb when i would choke it. I thought to myself... maybe the needle isn't seating properly or the float is rubbing the side and getting stuck. Upon review I didn't see any symptoms of that . I blew into the gas line part of the carb and air would blow through if the carb was right side up. If I turn it upside down then i couldn't blow through it. That was indicating to me that the needle was sealing. The bowl isnt overly full of gas. It appears to stop where the float pontoon line is.
After I ordered a new kit I started tearing the carb down ( I have experience with carbs just not this one but got my self educated lol). When reviewing the kit contents it also includes an idle jet. I noticed mine didnt have this installed in the threaded area by the needle and was wondering when my good friend cleaned it... did he failed to put this part back in?
This is where my head is spinning a bit..... When I looked at assembly literature online for this carb, it stated this model doesn't always use the idle jet. ??????????? Funny part is... the place i am ordering the full kit from has an online assembly manual as well. The kit includes that idle jet as i stated before. When looking at the manual it stated the same thing! but it is showing up in the expanded assembly view HAHA
Not even sure where the problem lies.
Maybe thats not my problem?
I had one guy tell me it could be a timing issue but i had this machine running last summer and fall so i dont think it is that?
I have had this carb apart 10+ times now. This tractor couldnt have died on a nice 78 degree day........ no it decided to conveniently do it with 3 feet of snow in the yard with sub zero temps and parked 300 feet from the garage...in which is not heated either haha I am glad i am still finding humor in all this. Fortunately i have nice neighbors that are blowing me out this year.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
