D17 running rough

I have had good luck by siphoning all but maybe 1-1/2 to 2 gallons out, then pull the bowl/petcock assy. completely out and let her drain.

Well I found part of the problem today.
There were a couple spiders in the bottom of the gas tank looking in with a flashlight so I decided to pull the bowl/ assembly off after draining all the gas and I found a ladybug jamdown inside of the assembly that the glass bowl clamps onto and was clogging/ restricting gas flow.
I figured that I had found the reason that it was running so rough, after putting it all back together it starts right up with the choke on but stalls within 10 seconds unless you keep pushing on the choke then it will continue to run but not the greatest...
I pulled the carburetor off and plan to go through it and see if there are any obvious problems and give it a good cleaning.
There's probably a good reason why when you push the choke it continues to run that I'm unaware of...
Any ideas?(before I filled the entire tank up with gas when I bought this tractor it ran great, so I'm guessing when I filled it and sloshed gas around it dislodged a lot of stuff and got into the carburetor)
Thanks Matt 👍

It's on a spring return ( let go of knob, choke off)

Does anyone know how the little critters get into a tank-provided the cap was always on ?? Seems like they can get anywhere :-(

I'm wondering if mine is spring loaded because of the exterior spring someone has added to it because they had problems with the choke somehow staying on? When I disassembled it there was a funky looking spring attached to the arm of the carburetor so that it has tension on it all the time...
I did check that everything was cleaned out after I found the lady bug and spiders in it and I also flush the tank out and looked in it to make sure there was nothing left...
I almost have to believe that something is in one of the needle seats in the carburetor or particles have something plugged off has anyone seen because it ran fine when I bought it but only started this running rough after I filled the tank all the way full and it's sloshed around and got plugged with ladybugs and spiders...

My uneducated no data behind it guess, is that most were not spring loaded from the factory but someone may have added the spring to avoid the choke being left on? That being said. The choke on my Ford Jubilee is spring loaded and if cold I have to put a clip on it to keep it running for a while till it warms up. Most of the Allis tractors I have played with WD series mostly did not have a spring on the choke.

Parts Book lists #70210742 as the choke return spring. We had a clip to hold the choke rod 1/2 out during warm-up as the spring would pull the rod back :-)

My WD-45 does Not have a spring on the choke and never did. Mine got to where I had to pull choke out to keep it running while raking hay last fall. Rebuilt the carburetor and she ran fine pulling the grain elevator. So in guessing you need carburetor kit put in. Just guessing mind you.   Duh I just realized this was D-17 post. My D-17 is a diesel so idk about cable 🙀

Your carb could have jets partially blocked from particles that came along with the ladybug! Take it apart, remove all the jets and clean with carb cleaner and compressed air - maybe a couple of times. Same thing with all the passageways in the carb body. And the fuel line and float valve in the carb. All it takes is a tiny bit of crud in the carb to really mess with how it performs. If necessary, rinse and repeat.

My D17 has a zienith carb, and seems to run fine with it. I like the Marvel carbs better for some reason. Just used to them I guess. Your tractor may have a Marverl TSX464. Look for the small brass plate riveted on under the flange area. I liked the kit I got from Sandy Lake when i did a 464 carb refurb this winter.

It looks to be a TSX 773 with a number 59 under the TSX part and number three under the seven seven three part here's 2 pictures of my carb off d17.

Matt,

I'm really hoping it's a issue with carb and not the gov or something else, but it seams like it should be b/c all this issue started after I filled tank completely and drove 200 yrds.before that tractor had no issue with running although now that I'm thinking back when I initially test drove it it was sputtering under load of a hill at owners place where I bought it🙄.but this is completely different in the fact that now I found the orifices blocked completely by a ladybug and spiders( got that taken care of last weekend) and even after all that cleaned out including the tank itself it would only stay idling when I pushed the choke lever every 10 seconds or so and if I let it go more than that it stalled...

I know, it's on my list to do( came this way last year when I bought it)
I'm not sure if there's a premade one I can buy or not?
Either through the crevices on cap or follow my thought here...
Spiders catch them and retreat into the neck of you gas cans which in my case would explain why I found 2 spiders and Asian lady bugs in tank.you are putting all of it into your tanks inadvertently.
It has made me check all my gas/ fuel necks before I use them( which I never thought of this before my findings in my d17 tank/bowl assembly and possibly the carberator ( I'll update this post after I clean carb out)
Thanks Matt
