I run on propane because my wife doesn't like the smell of white fuel in the house. I use a jerry howell suction diaphram homade, and use a propane regulator off a BBQ grill with a gauge to watch PSI. https://www.youtube.com/watch?v=LaVh6WZX9L0 I need to refine some of my machining....but this...

Finally it came together. I had to re surface the exhaust seat. Then run 2 psi on propane regulator before the valve. The Original carb and orifice is almost perfect for propane operation only modification i had to close two of the three ports. One port closed it runs lean and two ports close...

Right now using propane demand valve, a howell design. I will try to enrich it more. I have to choke it to make it run. So you're problaly on the right track. Perhaps it's not feeding fast enough. It's only hit every other every revolution at best. Rarely will hit every time, Very irractic...

I'm building a perkins hit miss from castings. I have tried to run in on white fuel and propane. I get the exact same results. Runs pretty good sometimes for 10 second, then start hitting every 5 - 8 cycles going too slow to trip the governor. THen it konks out. I thinking maybe valve sealing...

Good price is right. That's cool i live 10 miles from PM research. I'll have to stop up there. You would think a redwing would be my first build. Maybe next time. I'll think i'll finish it red with gold trim.

Not sure about what the RPM is. I just fired mine up last night for the first time. Nothing better than a piece of metal turning into a running engine. I will have to put a tape on my flywheel and hit it with the digital tach. My latch wasn't tripping fast enough. So i just did it manually...

I don't understand why they aren't more popular. I'm building one right now. I'm just behind where you are. I'm also going to put a electronic ignition in it. I also hand to remake my connecting rod out of alumium because of a Opps a daisy. But a real practical engine to build and casting i...

When building a crankshaft why is it recommended to silver solder and not weld it together with a mig? Is Penetration is better soldering? Or does the heat distort or stress the metal when welding. Thanks

I wanted to make an engine since i was a little kid, ever since my neighbor built one. Finally got the chance to buy a lathe and mill this January. I went all in and built an IC for my first engine. I'm so happy it runs. Still need to finish the governor and it's a little rough. But i'm so...
