[QUOTE="Loggerhead Mike, post: 96743, member: 774"] you will get some more throttle out of it, but you will not gain 5 hp out of it on such a small motor to make power the motors gotta breath. thats always the first place to start. port/polish the intake exhaust and i'd even polish the crank. after that you want more fuel (change carb jets). once thats working i'd start playing with high octane and timing. generally the slower burn you have (higher octane) you'd need to retard the timing a hair. theres really no rule of thumb you just have to play with it untill its right thats alot of work to get into though, may just want to find a prop that will give you more top end [/QUOTE]
