Today I got back to my speedex and trying to get it to run. I could not get very far fast with a pull rope so I looked for another way to try and start it. After looking at a few different things I put a belt between the pulley on the back of the engine on the speedex, and the pto on my wheel horse. Start the wheel horse and engage the pto to start the speedex. It actually worked pretty good and the speedex ran, but once you shut off the pto on the wheel horse the speedex would die. I thought it was compression so I tested my wheel horse for a baseline, and got 60, I tested the speedex and it was just over 50. I dont know if that is good or not. The briggs on the speedex, was firering, making exhaust, and you could move the throttle around but it would NOT run under its own power. I was going to take a video but before I knew it I had the gas tank off so I could clean out some of the rust. After I get it back on I will take a video. What do you think the problem is?

For your enjoyment, and better understanding here is a pic.

More than likely a fuel issue. if it's smoking it has spark. comp sounds fine.
How's the carb?

Nice old Speedex BTW!! Looks kind of similar to my Gard'n Mast'r

Good luck! I bet the carb and tank just need a little cleaning

Yes, I forgot to mention that, it probably has stronger spark then ANY of my other GTs. While I'm waiting for the tank to dry I will go clean out the carb. The carb I put on it was actually a borderline brand new one I had. I'm sure it got a lot of crud in it, I dont have a filter in the fuel line yet...

Looks kinda like your Gard'n Mast'r, but still very different! Lol.

Good luck Ryan! I bet when you get all the rust cleaned out of the fuel system, that Old Beast will prob fire right off and run like a champ!

I like your way of spinning the motor. The Speedex looks like it will be a fun GT.

That actually used to be the way that some of the old time tractors were started. The larger, higher compression engines were a real bear to crank start, so there was a smaller pull start engine on it called a pony motor that was used to start the larger engine. Great thinking Ryan! This is probably a dumb question, but are you sure that the PTO was spinning the Briggs engine the right direction?

Not a dumb question, but it is in the right direction of rotation.

Yes, it is spinning in the correct direction. I second guessed myself just before I engaged the pto.

I have often wanted to start engines this way that were contrary to get started. Just never put forth the effort to actually do it and end up with a sore shoulder LOL.

It was actually VERY simple and I'm glad I did it. Including the time to drive the WH around, find a big long belt, and align the pulleys it took about 10 minutes. I know I will be using this method in the future a lot.

Or you could weld a bicycle to the frame of the Speedex and peddle start it LOL. :laughingteeth:

No it would be great, Just make a swinging bracket so you can fold it out of the way when you drive. :dancingbanana:
