Thank you, didn’t mean to hijack the thread. Only think I’ve ever owned are 260s, 289s, 302s and 351s. I simply can’t think that small.
keeping the thread BUMPED!
The smaller engines are all the rage now. They use high pressure injectors to inject fuel and air at 100s of PSI prior to combustion. The effect is the small engine has an effective displacement of several times a conventional engine nullifying the ole Cu In. comparison. Check out the Rotax engines. 400 hp in a bread box.
