Kellys ongoing goofy thread...

My buddy has a Sears Allstate with the Puch 250 "Twingle" engine. He has a hand-made side car on it that looks like a vintage wooden powerboat. I will try and dig up a picture of it.

Here it is.

I wonder what that sounds like when running??

I wonder how it runs??
That's a wild design. Is the rear piston the intake, front the exhaust??

Cool, thanks Kelly.
So, yeah, one intake & one exhaust piston but both doing work on the power stroke.
That's the weirdest 2 stroke I've seen man

Were they any good in their day? Like more power/ecconomy...or just odd

Zose crazy Germans

If only they'd come up with the expansion chamber earlier eh?

An expansion chamber would be redundant on a two piston single cylinder, the pistons are acting as a fourstrokes valves would.
Or have i yet again grabbed the wet end of the stick?

Juicy, maybe so. I was just saying that if they had found the pipe earlier it would have made life so much simpler for them than all the extra pistons & rods, supercharging piston etc.

Still, what a machine
