Starting engine trolley

I put some trolleys together for starting engines.

I don't have much space so everything needs to be able to be tucked away.

Nice, Haus. I have a 4x4 pallet that I use for the same purpose as well as enabling me to run the engine. Has a well for the drive gear to dip into oil and a 5 gallon bucket for cooling. Works ok. I'd imagine if I worked in a shop I'd make someone that was more compact and easier to swap engines between, and maybe lift up to workbench level
