thank you very much for the detailed video sir, very helpful! I also have the same crack on the right angle fuel line connector that goes into the carb which I ended up fixing with a couple layers of heat shrink on the connector and teflon tape on the nipple
I have this same cultivator/tiller and had it since new. Today, I took the carb apart and noticed something that could be your problem. At 17:48 of your video, you show a "port that may be blocked" and you then said you sprayed carb cleaner into the port. Well I too felt resistace in that same port/passage when I inserted a small wire, however, on the other side of that passage a very small circular membrane popped out of my carb when I applied a little force with that small wire. I checked online, found the Technical Service Manual fot this Tecumseh engine and found out that a small circular part is in tgat port and its a check-value. I then very carefully reinstalled it into the carb with a small allen wrench and it snapped back into place. So, the resistance in that port was not blockage, it's a check-valve. Hope this helps.
Having a different issue with an older model just like this one... the return spring on the butterfly that's integrated with the carb has broken giving me a runaway throttle... not good... as you state in this video, the carb is no longer available so I've cannibalized another carb and swapped that spring onto the TC-200 carb... going to reassemble this week and hopefully it should work fine!
At 16:25 you have a clear view of problem. The plastic fuel input elbow on these carbs are notorious for splitting, resulting in leaking fuel & loss of power, if it will even start. The plastic elbow simply pushes onto a metal stub protruding from the carb. Fortunately the elbow is still available. Tecumseh part number 640363.
Holy shit. You are one of only 3 videos on this entire site that has THIS model of carburetor. And definitely the most detailed. You cannot find replacement carbs for this model of tiller on eBay, Amazon, Jack's Small Engines; NOTHING. My father in law and I banged our heads against this thing for about 3 weeks, and it's been laid up in his garage since then.
Mr. Steve, if you were somehow able to forward me the info you were able to pull to fix that carb, I’d be mighty appreciative. If you search TC200 or 300 online, everything Google spits back at you is wrong. It’s so frustrating.
I did the same thing with the o ring. I got to order some gas lines for mine for sure. The white plastic piece on the carb where the fuel line connects is also cracked on mine. Do you think that could also be an issue? You can see that crack when you are trying to get the carb out at the start of the video. Not sure how to replace that piece and if its not an issue I want to just leave it alone. 9:16 is where you can see the issue
Yeah, I guess if you’re an engine whiz who can handle the most obscure carburetor of all time. This video just might help us get the damn thing running though, so that’s a big plus.
On the spacer did you put the groove towards the carb to switch sides or towards the engine? I’m messing with one now and could not tell if the small hole goes to carb and the u groove changes it the spacer 1 hole goes to carb and changes on back. Thanks
I took the carburetor off my troy bilt tbc 304 and there is a small conical spring and I cannot figure out where it goes. Do you know? I cannot find specs with details of the carburetor anywhere!
Sorry I do not recall, and I do not think any parts manual for the tiller shows the inside of the carburetor. Try searching for exploded views of the carburetor by make and model stamped in the carburetor body.
