Here's an idea...
Having little to no experience in 1/2A, maybe TT timed their little .07s in a similar manner as their larger counterparts. When they ran them and got a reliable runner they said "ship it" - not knowing that the smaller engines really need a much higher HP/weight ratio than their larger cousins. (i.e. with no regard to maximun output) Sounds like a little work with a Dremel
would improve breathing greatly.
But isn't this really a moot point? I mean if they're being discontinued...
