Troy built tiller starts chugs along and then kills full size mod

I'm sorry you are having trouble with your Troy-Bilt Tiller. I have a genuine Troy-Bilt and I miss the original manufacturer and the help they provided me with my 30 year old machine.

I believe your trouble is in the needle valve adjustment. If you check the bottom of the carb, you will find the needle valve. It should be open about 1 1/2 turns and then fine tuned open or closed a bit to get the best speed. There is the possibility that your carb is dirty inside and could benefit from some carb or injector cleaner. You may also benefit from installing a new spark plug as well. Sometimes, in older engines, you can benefit from using a spark plug one or two heat ranges higher. You will have to experiment with these options to find the best for your situation.

I hope you find these suggestions to be of some benefit.

I agree it sounds like a carburater problem. It may need to be taken apart and cleaned. I hope that adjusting the valve on the bottom of the bowl fixes it but if it ran good the last time you used it it probably has gotten dirt in it or rust bits from the gas tank and will require cleaning.
