Hello! I took out the carb and cleaned it out. Worked for a couple mows but back to the same startup problem. Replaced the spark plu\\\\\\ this is normally the problem but a no go this time. I have noticed the primer doesnt function properly. I prime and dont see/feel the gas being loaded into the main chamber. I did notice the gasket has deteriorated partially from the primer. So I assume the solid seal (gasket) is the reason I dont see or feel the gas loading into the chamber being the problem? Can I pick up this gasket as local home depot. Troybilt machine.

You still have trash in the carburetor blocking or partially blocking. You are going to have to get some spray carb cleaner and be very thorogh about cleaning it, every hole, every passage, every thing. While you are at it if you have not recently changed the diaphram, go ahead and do that since you have it apart. The diapham is not expensive.
I can only go by what you say was done. If you took mower to repairman then it should run. If you took to a buddy who thought he knew, WELL. Try this first. The primer button is a round button usually BLACK, CLEAR, or RED. Look around your mower and you will find it at the end of the carburator. Carburator is opposite the muffler on your mower. With new gas in your mower ,press the primer button three or four times. Try to start. With all you have done it should start. If it doesn't start, think back and try to remember if you hit something while mowing, if you did then your problem is your timing. With the hit you sheared your timing key. This key keeps your fuel ,compression, and spark happily together to keep your engine running. Check the other things first and please get back to me, I will be more than happy to help you further. GOOD LUCK.
I think my mower is doing the same thing. There is no fuel getting to the carb but there is fuel being pumped through the filter. I took the bowl off the carb hoping I would find an obvious problem but nothing looked out of place. Get this, when I put the bowl back on the carb, it started! I mowed the lawn thinking I inadvertantly fixed the problem. A week later I went to mow again and the same thing happened agian, it wouldn't start. So, I did the same thing and took the bowl off the carb, looked at it and again nothing looked out of place, put the bowl back on and again, it started!
I think the float is somehow sticking. When I look at the inside of the bowl it has slight vertical rub marks as if the float is rubbing and possibly sticking to the side of the bowl but why would it start doing this after two years? I'm no expert technician but I know floats don't grow and bowls don't shrink. Hopefully someone out there will have a solution for both of us...any takers?
I am not sure what type of carb you have so I will give you a couple of ideas. 1. If the carb is one of the plastic ones that attaches directly to the gas tank take of the air cleaner and press the primer bulb. If you get a spurt of gas and not a stream of gas get a new diaphragm for the carb. It goes between the tank and the carb. 2. If there is a sediment bulb hooked to the carb drain the gas from tank and then carefully remove the sediment bulb and clean it. 3. If there is a sediment bulb hooked to the carb and a flat paper air filter attached to the sediment bulb via a plastic air filter holder with a primer bulb built into the air filter holder replace the gasket between filter cover and sediment bulb.
Carb. float must be stuck open. First if you have no fuel in the tank it must all be in the crankcase.Drain the oil and refill and also check the carb as the float has to be sticking open. Hope this will help you. Donnyb60
first check to see if you have good clean gas in it. No water. if you have good clean gas. then I would recomend taking the gas tank off wich should have a plastic carburetor mounted to it. after that is removed and free of excess dirt. take the carb off there should be 5 phillips head screws. pull the carb off gently while observing just how it all goes back together. you may want to take pictures. you will find a fuel screen that you should take off and clean with carb spray. also there is a fuel pickup tube clean that also with carb spray. a couple words of caution if using compressed air Do not carried away with it. also same with the carb cleaner to much of it in rubber primers is not good.
