Stiff diaphragms won't move fuel. Need the trimmer model #. If it's MTD made, may be like 41AD254X966. Search web for model & get carb part #. Common MTD one is 753-06083. I rarely see a rebuild kit for these barrel carbs. AM carb is ~ $12. You can get an OEM carb for $50.

 

It's not even try to fire up now after priming and spraying gas into the carburetor. I forgot to mention it had an empty tank before I filled it up. Could the engine be broken because of it? I can hardly feel resistance when I pull the string now.

I have a Craftsman mini-cultivator that if I store it with gas in it, the gas will leak into the crankcase and dilute the oil. Check the oil level to be sure it is not diluted and overfull now.

 

Empty fuel tank won't break a tiny 4 cycle. Is oil at proper level? Rough compression test - pull the plug, put thumb over plug hole, pull rope...does pressure try to push thumb off?

 

I got the engine to start now. I feel pressure when I put my thumb over the plug hole and pull the rope. I retested the spark plug and realized that it was not sparking all the time. I cleaned the contact to make sure it was good and sprayed some gas through the spark plug hole and the engine started. I kept it running for a few minutes and ramped it up. I assumed using fuel from the fuel tank at that time.

 

I’m guessing as oil was getting out the air cleaner, oil was probably getting into the cylinder and coating the cylinder walls in oil (which would make it easier to pull) and oil coulda fouled the plug which would be why it won’t starting. Good job at gettin her going tho!
