Yes, cute is the best word I guess. It reminds me of Arne Hende and all his little cute engines.

Re: Tiny 0.25cc Tiger
Hi there Ian! Great to hear from you! Nice little (tiny) engine you've got there. Is there a function to the concave-radiussed front-portions of the cranks on those engines? They look a bit like "pulleys".. but would be to wide to grip a belt..
Maybe an afterthought to the original design to put more space between the prop and the needle.. without having too much mass?

Not an afterthought - Oliver Tiger engines were primarily for combat and team race requiring fast restarts and this is the lightest way of having distance between prop and needle. It may not be obvious from the pictures but these are ball bearing engines and lengthening the crankcase would push weight further forward.

That makes sense to me Ian. They're very nice-looking engines. Have you run the "tiny" one? How exactly does a 1/4cc engine compare in cu. in.? I feel too burnt-out to do the math.. I know that one liter in regards to automotive engines equals approx. 60 cu. in but cc's..... well it's Sunday night.. I played a gig this afternoon and I'm too tired to figure it out.. Being predominately European; diesel displacements are typically classified in cc's. I've often wondered how to compare them to the cu. in. designated engines.
Re: Tiny 0.25cc Tiger
Roddie, you got to love the metric system One litre is 1000cc as the litre volume is determined by a cube of 10x10x10 centimeters. And that volume of water weighs exactly one kilogram. It makes conversions (between metric units) easy.
Anyway, that cute little Tiger is about .015 cu in. Pretty impressive!

Re: Tiny 0.25cc Tiger
Metric is really easy when one has grown up with it.
It is quite easy though to remember that 1cc is about .061 cubic inch, and then use a calculator...
