Trying to get my motor to idle better Notice the carb linkage does not move till 1/4 inch past the timing mark
Is it worth resetting or is it close enough
Thanks

September 11, 2022 at 10:12 pm #265902While on this topic…..
Had occasion yesterday to look at the Fuel saver settings on my twin ’56 Johnson Javelins. One engine had been really bogging down drastically toward full throttle. Turns out the little slide collar had dislodged on the rod on this engine.
I checked out Frank’s link, and my 10th Edition Manual pages 162-163.
I followed instructions about holding the armature plate against the boss on block (full advance), but noticed that the carb shutter was not going to full open against the little boss on the carb. I pushed the saver-linkage forward so that the shutter on carb touched its boss, then slid the collar rearward to meet the pivot pin, throttle at FAST and secured the collar.
I assumed that I now would have maximum advance and wide open throttle coordinated? There was no mention of this last step of getting the shutter to touch its boss before securing the collar that I saw.
Poor assumption on my part?
Took the boat out on the Lake, and it really scooted along with both engines humming smoothly at maximum throttle. Performance has never been better.
Any comments or suggestions would be greatly appreciated, sorry about the “wordy” account. Bill.
September 13, 2022 at 11:18 am #265982Just make sure that the carb throttle is not “preloaded” tightly against its stop by the economizer linkage rod, this will cause the throttle plate/shaft to wear prematurely.
And sometimes it is easier to have an assistant help make this linkage adjustment. Not enough arms/hands/fingers to hold the throttle linkage wide open and adjust the rod.

I will check for a little gap at the boss at WOT position tomorrow.
You are also “right on” with the assistant idea!
Bill.
