Half Scale Ford Quadricycle Engine

Thank you Ross!

I think the O-rings are breaking down but they do a fantastic job holding compression. Once I switch to Viton O-rings they should last a lot longer. My Ford plumbing engine has had the same Buna-N rubber O-ring for 3 years without a problem. This engine will get a lot hotter so I think Viton should help.

Here are a few pictures from today. Very strange but the engine will only run off fresh gas. I had gas in the tank that was a day old and the engine did not run. I replaced the old gas with new gas and the engine almost jumped off the table. Shortly after running for a minute or so it stopped and has not kicked over once.

Anyone know what this means?

After a couple of shows I decided to add a counterweight to the flywheel. Ford originally had a counterweight on his Quadricycle so I decided to do the same. The engine would begin to shake itself apart.

It runs much, much smoother now.
