Rupnow Vertical first run

[Captain K]

Why not make an engine that is like 3 or 4 horsepower
so you can use it on a mini-bike or a go-kart or something?
A friend of mine converts single cylinder air compressor
pumps to engines and puts them on bicycles.
Ends up with something you can ride that way.
That is why I really like those small steam trains they build.
You can ride them around.

It's not what I want to do. If you want to, go ahead and do it, then post a video here.
It's a hobby, I only do what I want.
Thanks

I'm waiting for Brian to give me some V8 plans... I know he can do it

And angled display shelf for 8 singles?

Thanks for the compliments guys. I think I have a several small air leaks on intake and carb. Doesn’t run as smooth as I would like. Also doesn’t pick up the gas a well as it should. If I pressurize the fuel tank it smooths out and runs a lot faster. Getting too much unmetered air I believe. I think maybe the jet sticks up too far into the air stream possibly disrupting the smooth flow and lessening Venturi effect. Going to try a few things and I’ll post a video if I get some improvement.
Thanks for looking

I know from tinkering with my model airplane engines that the orientation of the orifice within the airflow of the carb makes a big difference in how well and consistently the engines run. And leaks, even small ones, are a big no-no. So you're likely on the right track for better running.

Nice job. It's always a great feeling have something that you've spent hours on come to life!

I often get the "that's cool, but what does it do?" or "Whats if for?"
I usually tell people, "its just for the joy of it" and go on to tell them its a work of art like a Picasso.

I'm getting bit by the model IC engine bug. Love to put Brian's Flathead engine in a model tractor.

Captain K

You can feel proud to have finished the project and that it actually does run as expected. Brian can feel good that his drawings are of a quality that let you succeed. Both of you should be smiling.

When the locals ask you "what does it do?" Give them a blank stare and say "If I tell you I will have to kill you".

Pete

Excellent work, both of you! This is very inspiring indeed.

Congratulations. Your engine runs fine and it is a great accomplishment.---Brian Rupnow

[JoeLee]

Pretty quiet running.

[bandsawguy]

Great job!

[BCRider]

Yeah, that's quite an accomplishment ! ! ! So many things to make and fit in any engine.

That's a form and size which would go nicely into a model boat as a "sort of" open style launch or old one lunger fishing boat. Any plans for something like that?

[tom_d]

Nice!! Congratulations on a job well done. It sounds great.
