hi all, i have an old craftsman rider with a 10 hp vertical tecumseh. i have to full choke it for a few seconds, then put throttle to idle to get it to start. i have to do this 3-4 times before i can get it to run.if you try to give it throttle it will die, it will take throttle after a few tries. i have had the carb apart a few times and found nothing wrong.am i missing somthing?

Yes. Those carbs have several tiny passages that were plugged at one end, at the factory, with small steel balls. Those passages are nearly impossible to clean. I've had to soak the carbs in carb cleaner for days and hen use compressed air. Down load the manual on the Tecumseh Carbs. Good Luck, Rick

Why do they have to make things difficult.  What happened to KISMIF ?

Is this an old enough machine to have had adjustable main and idle mixture screws? Not taking gas from an idle sounds like the mixture needs to be adjusted a little bit richer. Turn the idle mixture screw out 1/8 turn at a time and try it to see if it helps.

i tried that to dodge. thing is after i get it started and warmed up it idles and i have good throttle.the engine is in good shape, i wouldnt even mess with it but the tractor is an old amf built, ugly as sin but i use it at work to pull a little lawn trailer. it grew on me so i think its worth making it right.

I have had good success with filling the carb up with Seafoam and letting it sit for a day. Make sure the piston is at TDC then (with the spark plug in) fill the carb till it won't take any more. The next day take the plug out and turn it over a few times to clear the cyl and carb out. Then try starting it with just seafoam poured in the feed line.

Does that have the Plastic Emulsion tube in the carb with the 2 goofy rubber seals?

 

If it does have the plastic emulsion tube then see if you can find and replace the 2 small O rings.If they are cracked or leaking you will never get it running correctly.

Here $4.74 for 2 shipped lol.

This is what they look like installed on the emulsion tube.

If has an lme carb, which it probably does it has a brass emulsion tube. Once you unscrew it you need a service replacement. Or you need to take yours and cut a Grove around the holes that are in the threads. When you put it back in. Or it won't run

That is a fact for sure, found that out first hand. However you can get to the ports and all clean after it is out, and when I put the service nozzle in, mine now runs so smooth and nice it's like a new motor.

I have had a few times in the past rev up the engine with the breather off and at a high mid to high rpm choke out the carb with my hand. By doing that you cause all the suction to pull through the jets, sometimes pulling the debris through and fixing your problem. That only works if you have a piece f dirt , if its clogged up with that white hazy crap it needs to be cleaned out.
