Rehash: got 20 bumpin 21 just me @ 3400 rpm. Played with carb linkage and got 20 bumpin 21 with my ol man and me @ 3510 rpm. Didn't know if it was the linkage adjustment or the boat ridin more level.

New update: went out today after setting the throttle linkage to engage immediately when you twist the throttle. Before it would engage after about 1/3 throttle. After I did that I checked to see when the carb plate fully opened. It was 100% open at half throttle. So I think should give me max rpm at half throttle. Start it up in the parking lot. Sure nough, 4250 at half throttle twist. So I take er out. I'm hitting 22 bumpin 23 at 3650. Now here's the really funny deal. That was at full twist. The carb fully opens at half twist. So I thought after a couple minutes let of to half throttle since it should run the same. Well immediately after lettin off it lost rpm. So between 100% down to 50% throttle I was loosing rpm. But the plate is fully open at 50% rpm. What gives y'all?

A motor wraps up faster when there is no load on it.

Looked closer tonight. Took a nut out blockin the throttle linkage plate from turnin. Got 3800 at 23 mph with me, my boy-75 lbs, my ill gal-55 lbs, and my dog-65 lbs. I'm good with that. Lookin forward ta runnin er myself.

def. should turn 25 with just you. Get those heads done and you are gonna have a really nice rig I do believe. BTW, what is a 120# control unit?

Thanks Clay. Yup. You got er.

Heads will be done in a month er two. Lookin forward ta that!

I think you kinda misunderstood what Woodie was sayin. The motor aint gonna turn up the same rpm under a load that it will in neutral. Think about it like your truck. With just you & a 12 pk of beer, it'll peg out the speedo, but put a load back there like a big tractor or something heavy, & you can give it all the throttle you want. If the horsepower aint there, the rpm's won't be either.

Understood TC. Maybe I did a chit job a explainin it. Ta break er down simple, none a the linkage was adjusted right all between the throttle rod and the carb.

Final update. Ran er tonight and bumped 25 and steady 24.

Gps said 29 at one point but darn sure that was a glitch.

dang right! Getting it where you wanna be.
