hello, first post, didn't see an "engine" forum, so here goes- i can't find
much "review" info on the axe rossi .25 cobra. #1-is the longevity good enough to justify the xtra $? (2 or 3 times the norm, maybe?) #2-is a .25 really a combo of .28'ish power,and .21'ish fuel mileage? i've not owned a rossi engine yet, but i know they are very high quality.

great forum, thanx for any advise, info.
