I recently bought a Poulan 19cc conversion gasser for my 120 size bipe(weight - I don't know). My problem concerns the way engines are rated or labelled. I was told that 1000cc's equals a .60 size glow; so that would mean my Supertiger 3000 would be equal to a 1.8, right? OK, then this new poulan 19cc would be equal to about an .074? Something is not right here, but I don't know if it's the numbers, or me. Can someone help a certified old fart?

Thats some funny math.

19cc is 1.20
10cc is a .60
50cc is 3.0
100cc is 6.0
62cc is 3.8

The label on the 19cc weedie motor means nothing for our modeling purposes. Pay no attention to it.

A ST3000 is 30cc--------or 1.8 cubic inch. Same same.

Your 19cc engine is 1.20 cubic inch. Should turn a 15-8 or a 15-10 up around 7000RPM +/-

Hope this helps--from a certified young fart.

10cc =.60 cubic inch or close so maybe a 20cc might be 1.20 cubic inch. 40cc may be close to 2.4 cubic inch....I think I read somewhere in a forum. But the guy was not sure if his cousins uncle told him right!!! No name

The formula to convert CC to cubic inch is this: CC X .061= cubic inches. 19cc is 1.16 cubic inches.

Hope this helps you.
