is the plate vibrating a wear issue ?What is the magneto plate bushing ???
I had to replace the coil on those old engine evinrude/johnson ..1965/75
is the plate vibrating a wear issue ?What is the magneto plate bushing ???
so i orderd a locating ring so i can set the coil properly, i did order a new driver coil, not saying it is bad, but it is original. so to elimanate issues before i go back and look at the carb again. ill change those parts and see if it improves.is the plate vibrating a wear issue ?

well the coils have a smaller defect on the very old coils ..the steel laminates have rust , coil lower voltage on the spark plugs.so i orderd a locating ring so i can set the coil properly, i did order a new driver coil, not saying it is bad, but it is original. so to eliminate issues before i go back and look at the carb again. ill change those parts and see if it improves.
thank you all for the help.

How do I get the idle to comeThe throttle plate should start to open in between the 2 dots. The 2 lines are for timing the ignition. The adjustment of the cam roller is for acceleration and not for idle.
I know I asked about the idle. But what I was looking for how to adjust the roller cam. So when the roller cam touches the 2 dots ? Is there a way you can point me to see if crank case is the issue or a test I can try to give me some answers to why I think I have a problem…We are now at post #69 and counting.------Idle issues are not always carburetor related.---And this carburetor has been cleaned a few times.------I am thinking there is an issue with crankcase compression.-----Not easy for a novice to diagnose.----Sorry ,----some inspection needs to be done.----Picture in post #67 is for earlier magneto.
I was just showing him the timing method. Are you going to tell me that you can't set the points on a 1974 model using the timing fixture?We are now at post #69 and counting.------Idle issues are not always carburetor related.---And this carburetor has been cleaned a few times.------I am thinking there is an issue with crankcase compression.-----Not easy for a novice to diagnose.----Sorry ,----some inspection needs to be done.----Picture in post #67 is for earlier magneto.

Okay. I just use the flywheel when timing points. Never used the fixture. My Service manual shows a fixture being used for that ignition. Maybe there are different fixtures.No I am not.----I believe bottom becomes top , and top becomes bottom if you use the earlier ( 1970 ) fixture.
Did you figure it out? You have to adjust the linkages and such so that roller it between those two dots or right at the first one when the butterfly in the carb starts to open. That is when the timing is starting to advance and you can use the increased fuel for power so the two have to coordinate together...the timing advance and the opening of the butterfly.I know I asked about the idle.

So last night before it got to dark out, i loosend up the red arrow ( picture below is the refrence) then i turned the handle till the blue arrow cam roller touched the 2 dots the yellow arrow. then i tightend up the red arrow. so when i turn the handle back to off will say it does not touch the plate , nor does the butterfly in the back move. so in this setup motor starts right up i can get it to idle ok at a higher rpm. but i am new to this and seem to keep going back to the carb. so to eliminate the carb i need to set it up properly first.Did you figure it out?

is this the gasket you are refering too. i did replace that when i rebuilt the carb.Where is the gasket that goes around the nozzle?-----Fuel must all come through the high speed jet.----That item is hidden inside the carburetor bowl.-----When throttle plate is closed there is still a calibrated amount of air and fuel allowed into the engine.-----It must be so , since an idling engine needs OIL to keep running.----That lubricating oil is brought into the engine via the gasoline !
so the next question is this part circled i know it stops you from turning the handle to a slow speed that it will cause the motor to turn off. question is what is the starting pont for this to be, how many turns out to start off.Correct , that is the one.
