Check that the primer bulb has no cracks in it.I would change the primer bulb you have air getting into the fuel system that is causing your fuel to run back.

about the thickness of a match book or business card is usually sufficient If you need further help, I’m available over the phone at https://www.6ya.com/expert/kelly_69a0cf1b13789df1

it could be the overload protector or the electrical cord has broken inside so it isn't getting the power it needs or the brushes in the motor have gone out If you need further help, I’m available over the phone at https://www.6ya.com/expert/kelly_69a0cf1b13789df1

There are two starting procedures - initial starting after long storage or running out of gas calls for squeezing the bulb (note - squeezing the sides together - not pressing the bulb in) 6 times, poulling cord up to 10 tiimes, rapid pull. If that doesn;'t work, wait 15 minutes, do not press bulb, but pull cord 10 times again.

Normal starting after first use and w/gas in the tank calls for 2 presses of the bulb.

I found that I was not priming the engine well, but also it should not be as much of a pain as it is. I still am successful in starting on every third attempted use, get frustrated and say %*&% it most of the time. These things are made by MTD (for Troy-Bilt) and that, in my experience, stands for Machine Typically Dead.

Hope this helps.

Check for a broken pin or loose grub screw in the drive area of the box.

there is a engraved line on each gear line them up

look for a cracked fuel line or a split in the primer bulb

You have to pull the spark plug and fill the cylinder with some small rope then using a big pair of locking pliers you can loosen the clutch. There should be markings on the clutch as to the direction to unloosen.

I would try using some solvent to clean the carb. It sounds like the float valve is not moving freely, therefore not letting enough fuel into the carb. Be careful though, solvent can be a bit rough on the engine, so be sure to drain it out of the fuel bowl and replace with the appropriate fuel before starting the engine.

Hello , well you again, on some of the small tillers the tines will engage because that is the way they are made to do on start up,it is not a clutch issue,ad far as i know there is no way to disable this,it is a pain but this is the way it is,,hope this helps,
