Increasing 9.9-HP to 15-HP
Posted: Thu May 30, 2019 10:02 am
Regarding changing the carburetor in the 9.9-HP engine in order to increase its horsepower to 15-HP: if you want a 15-HP engine it would be simpler to just buy a 15-HP engine. To turn the 9.9-HP engine into a 15-HP engine may require more than just changing the carburetor. Also, in the carburetor you may only need to change the jets; you may not need an entirely new carburetor.
Generally I don't think tinkering with the engine carburetor is likely to lead to a big improvement, but if that sort of modification is in your realm of work, then, sure, give it a try, and particularly so if you just need to a few $10 jets.
