The old Bozo is chasing me again. I saw some clear plastic tube on my carb pickup roller and scratched my head. The roller was too thin and not spec. Bozo wrapped it with black tape and added his new roller??? The addition of the hose would lead me to think that the set up was lean and late.

That may explain my poor mpg. Doh?

Indeed, why do people do this?

Anyone local have the OMC ign. analyzzzer? For an ois motah.

I put the correct roller on, but I need to set the timing. Please folks with old smokers, the carb advance is very important, and the timing advance is critical. I would advise backing off a degree or two with the "new" gas. Pre ignition can lead to boom. Feed the Motah.

Cheers,

Sandy, if your motor is set up like my old 115, the throttle cable pushes a lever that advances the spark. There's a cam on that lever that the roller/carb linkage lever rides on. If the roller was smaller than spec diameter, the carbs would open less and later than spec, so yes, lean and late. If the tape/hose or whatever was LARGER than spec roller diameter, the carbs would open MORE and sooner than spec, so I would expect that to burn more gas, but less likely to hurt the motor. Lean would reduce power, might make it run hotter, and could lead to detonation/pre-ignition which can be fatal pretty quick, as you mentioned. When I rode in your boat during our prop trials, it didn't seem to me that you were down on power that much compared to my motor, and if it was lean, you might have had problems by now. I'd bet it's running a little rich (and thirsty!) Did you ever get a factory manual for that thing? It has good pics of the throttle linkage/rigging. Denny

Classic example of presidential engineering...

Anyone want a Clymer? Got my Hogans Heros lunch box replete with factory manual.
Captain Craig has the analyzzzer. I don`t think I could have made west end w/ out Jerrys.

Gotta keep that suckah fat n happy. Read your plugs. They always tell the story.

Thx Folks!

Ken.....outstanding!!!! "Presidential rigging" comes a close second!!!!

Hey Sandy, if your engine is sick give it a name, a minority name works best, and then process a claim with Obamacare and waaala, you will have all the money you need to fix the problem. Change your outboard mechanics name to "Dr. Something", like Dr. Bushwacker as an example, have him process the paperwork and your good to go!! The odds are you will not only get enough to repair the engine, you will also get enough to buy a new one!!!!

She`s named LaCasha.

"LaCasha Flow Johnson".........perfect!! That's got easy government money written all over it.

[gofastsandman]

Good one Don!

Or LaCasha Cross Flow Johnson. She`s uppity.

Actually, she has been golden to me. Knock knock.

I keep learning and sharing my love.

I rebuilt the vro for 62 clams last spring. Two parts don`t come in the kit. Piston shaft and washer. Get new clamps too. No worm cutters.

Look at the design of the threads and apply 1/8 " hand driven feel.

Hey Sandy..6 Carbs = Poor fuel economy. The torque down low is worth it.
