"" I've made my Torro a drill start. But bladeit starts but blade comes off..when tightening blade no need for block of wood because it wont turn...Is my torque off?? ""

What you are saying does not make a lot of sense.

Some basics..

The engine turns Counter -Clockwise when it is Starting/running.

The Blade Turns Counter-Clockwise

To tighten the blade bolt it needs to turn Clockwise.

If you are trying to start the engine using a drill on the Blade bolt head. You are loosening it when you try to start the engine. At least you are if you are turning the engine the correct way.

If you are using a drill on the flywheel side. I sure hope that you are not trying to use a socket or tightening the drill chuck onto the small end of the crank shaft. For if you are using the blade bolt, socket on the flywheel nut or tightening the drill chuck on the crankshaft. Please get your wife or someone have 911 on speed dial. For you are going to need them..

Your torgue is fine but I think your rocker is off !

Using different socket on fly wheel.... Thank you for the counter clock wise info.

Using old modified tire iron

Whitewall?

Mike- if i read your question right, the blade only spins with the engine shaft - not freely and wiggles loose when running... My rider did that. It turned out with the pulsing of the engine running, there was enough slack for the blade to oscillate wiggling loose. Look at the mount\blade adapter and the blade itself. Any even small wiggle is enough for the oscillating to back out the bolt.
