Friction Roller Slipping Out Of Adjustment?

I always have difficulty setting roller engagement. I have to hold the engine down while adjusting the quick-release axle. Of course the nut on the other end is turning. I need THREE hands to do this!

What I will do is attach a ratchet strap from rear axle to the QR skewer or my new 1/4" X 6" bolt. The strap will hold the roller on the tire while I tighten everything down. Then when the wingnuts are tightened I remove the ratchet strap!

Installing a ratchet strap can also eliminate the havy springs or bungee cords on the DIY weedwhacker installs.
