My Trailer Hitch / Engine Stand "Invention"

#1
Way too humid to think about spraying any kind of paint today, even etching primer...so I took a break from the trike project and me and the kid started messing with the motor for it. We've been tinkering with it for a while now...replaced some parts, installed a new set of points cleaned up the magneto , etc.... but have never tried to start it until today. We flushed out the tank real well, ran a temporary fuel line, and installed the rebuilt carb . Fresh oil and gas...ready for the big moment.....
We had it on the floor and then tried bolting it to the top of a milk crate but it was pi**ing me off because I was hunched over and it was moving all around the place. Top of the bench is too high, gotta stand on a ladder to pull the recoil :doah:

"I need something solid to bolt this S.O.B. to....!!!"

Ahhh necessity, "The Mother of Invention".....in less then 10 minutes we whipped up this handy little engine mount using an old trailer hitch and a piece of steel plate I had lying around....



Here it is in action:



Man it's nice to have an engine bolted to something solid (Like a 2 ton truck) when your pulling on that rip cord . Two bolts diagonally are plenty to hold the motor in place.
Also keeps it at a nice height for making carb adjustments, checking the plug, points, changing the oil...just working on it in general :thumbsup:

It's hard to see but the motor is running in this last photo....if you don't belive me just try touching the pipe on your monitor :glare:



Of course it could be altered to suit your needs or made a bit fancier.... welded up etc....1/4" plate with a gusset underneath would be ideal. I only paid $5 for that hitch at a local flea market so I may go ahead and make up a more "permanent" version to keep around the shop.....maybe add a few different bolt patterns for Briggs, Clinton etc...

>>>> I'm gonna start it up and drive it around town...tell people I figured out a way to power my truck with a lawn mower engine and I'm saving thousands of dollars in gas....maybe I can get a government grant or something.....everybody else does. :smile:

OHH great now I have a finger smudgee on my screen.:doah:

At first I thought it was a backup engine "just in case" but after reading I understood.:lol:

I built some similar devices out of the engine plates of edgers I had robbed the engines off of, and welded a 2x2 piece of square tube unerneath to mount in a vice. Like you said, it is awkward to pull the rope sometimes, but everything else is nice to have at eye level.

Old thread.....brought it back to show the updated version:



Looks like a motorized skateboard.....but I just added an old gas tank and throttle so I can better control it....

Still need to add a brace underneath or use a thicker mount plate...but it works pretty well.

That's a good idea Gerry, I built a minibike table this fall and I included a engine plate from a old snowblower on it to bolt motors on to run them, I'm gonna coppy your throttle and gas tank idea for it. Thanks. :thumbsup:

...the "handlebars" are just blackpipe/fittings with 1/2 a coupler welded to the plate.

Good idea. I use a pressure washer cart set up for large and small engines, and a modified engine stand for paint and assembly. They both work like a champ. I need that throttle set up, A string on the throttle just dont cut it, :laugh::laugh::laugh:

Yeah, the motor in the video had a sticky return spring....that's why you can see me helping it...I didn't want to blow it up since it was for sale :biggrin:

but it normally works great.

Since the same cable is being used over and over, I soldered the tip so it wouldn't fray.
