dug a bit further into the 13cc engine, figured out the reason it didn't run for the previous owner is the external pulse line was cracked, easy enough

this thing is a pig weight wise with stock ignition, 3lb 10 oz without a prop adapter! will trim it further to get rid of all ignition related components and trim rear crank stub. estimate of about 2.5lb on gas/glow

on an external comparison it is identical to the 16cc, so the 16 is probably a bored version (or the other way around) which would make the 16 about an ounce lighter, the 16cc is .1" bigger bore and no bar in the exhaust port (similar to the difference between a homie 25 and 30), exhaust pattern is the same wierd offset thing, same muffler, the 13 has a wierd 45* intake adapter thing which is why it has the external pulse, will get pics up later.
