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.

Take the fuel bowl off and clean then clean the fuel jet. a partial plugged jet will do this. could also be the float in the carb is sticking shut so could need cleaning as well. Would do good to run fuel cleaner through a tank of gas to clean things up. This is just an idea but worked for me.
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?
Hi there. I can help you. The problem is that your carbeurator is gummed up. You may have to remove the carb. and soak it in carb. cleaner for a few hours to get rid of the gum. However, I have often had luck with a fuel additive called seafoam and a carb. cleaner spray plus some starting fluid. Put the seafoam in your fuel using one ounce per gallon, then remove your air filter and squirt carb. cleaner in the air intake, two five second blasts. Try to start the mower. If it starts, great, if not let it sit for an hour while the carb. cleaner dissolves some of the gum. Try again ain an hour using more carb. cleaner and some starting fluid, a couple of blasts of each.
