Ok, I got the motor to run. I checked the idle fuel port and it seemed to be plugged. I also forgot to check the sparkplug gap. It is supposed to be 0.03" and when I checked it, it was less the 0.25. For those of you who don't know that means I will get less of a spark. So I set it to 0.03". The motor is very spurattic and not much power. It will contiue to run with the tiller engaged, which is a good sign. I am thinking about taking the main jet out of the one I ordered and replace the on in the OE carb with it. The thing I hate about this type of carb is there is NO adjustments you can make other than setting the idle, which this machine NEVER does. At least not to my memory. When you start it, it runs at operating speed all the time. Any suggestions would be great.

Here is a link to the motor running on YouTube.

Have a blessed day!

As I stated in the original post, I cleaned the gas tank and verified that I have unobstrucked flow to the carbuerator. I did completely clean the origanal OE carb and verified I can get ait flow through all passages. The frustraiting thing is that the OE and the new carb have the exact same results. The motor run for 20 seconds and stops. If I prime it again, it will do the same thing. It will keep doing this over and over. I don't have any problem getting it started. It starts on the first or second pull. It just won't continue to run. If I press the primmer a couple times when it starts to die, it will run a few more seconds. I can do this over and over. The only thing I have not replaced it the primer bulb. This is not like the ones with the two ports. This have only one port and a small hole in the middle of the primer button like the one in the picture.

Mine has an RUN/STOP switch. It is definitely in the RUN position. I have been working on this on and off for three weeks. I always double check the switch before I try to start.

Thanks for the suggestion though.

Have a blessed day!

I did try running it with the gas cap loose. I also tried running it without the filter, making sure beforehand that the gas was clean. Neither made any difference.

I'm really scratching my head on this one.

Hello
I have a Troy Bilt Tiller model: 21A24T1711. I am having an issue that it keeps running out of gas because I believe it is not refilling the bowl. The tiller was purchased back in 2018 and was used then and put away with gas in it. I know that's a bad thing. The gas did go bad and the carbuerator got clogged up. I tried cleaning it and I believe I cleaned it well but went ahead and bought a new one and replaced it anyway. It also has a new air filter, fuel filter, gas cap, spark plug, and fuel line. I clean the tank and am using fresh gas. I have verified that the gas coming out of the tank is good with no contaminants or water. I also veified that the OHV gaps is 0.005" as per the specification. After priming it will run for about 20 seconds. It will do this over and over. So I know that the engine will run. I know that it at least gets an initial prime. But why doesn't the gas keep up with the demand? I cannot figure this out.

I have included a reference pics.
