My gts Toro mower Model 20070 will not start with the electric start. If you reposition the blade you can then give it an extemely hard pull it will start. How can I make it easier to start so I can use the electric start?

could be dirt in the carby , blocked fuel filter or lack of adjustment in the accelerator cable
I will go for a cable adjustment as they slip under the clamp on the carby bracket when the throttle is pull wide open

Are you sure there is oil in the machine?
Are the Fins on the engine clean and not loaded up with sand and mud?

Sounds like it is running so hot that it is seizing.

You can download one from Toro...

From flipping the mower on it's side the top of the cylinder gets slightly flooded with crankcase oil. A good priming and a few extra pulls on the starter cord is usually necessary after this type of maintenance. You'll see a few extra puff of oil smoke upon starting. This burns off in less than a minute.

you will probably need to replace the tabs that pop and grab the fywheel, the springs should be replaced as well.

Did you check under the deck for clogs? If its not clogged, DISCONNECT the spark plug wire, and try to turn the blade by hand... Oh yeah, did I mention DISCONNECT the sparkplug wire FIRST! If the blade won't budge, you might have a seized engine. If the blade does move, the problem is in the starter recoil. Rewind the starter string, and check the spring for damage. Good luck!

check your mower for interlock switches that might interupt spark for safety reasons.

A chute switch or something like that. Check your owners manual for troubleshooting.

Unplug the keyswitch and try pull starting to rule out a bad switch.

If it still doesnt have spark you might need a new coil.

The coil is right under the recoil cover and are fairly cheap.

A set of hand tools and $30-50 for the part should do it.

Good luck and be careful.

there is a flywheel brake on them, possibly a malfunction there you will have to pull the top shroud off and see if maybe cable broke, that attatches to the brake which when you engage it so the eng. can rollover with pull start.It is a safety deal so that when you let go of handle the blade stops imediatly, Hope this helps

goto toro website and use model of machine to get blade model and use blade model in google to get prices and then order them

Check the gas and gas tank, you might have water in the gas.
