I have always tightened the screw for the points FIRST.---The wee cam screw adjust them.----Never an issue.----That screw for the points has that flat washer that allows this.
No need to do any sanding on the coils.----But the coils are NOT in the correct position.---They need to be adjusted/ set for proper clearance with flywheel.
??----This switch has a mechanical plunger!---Operated by a cam on the THROTTLE lever.-----The 1970 model 115 HP will start in gear at idle.----It will not crank with too much throttle applied.-----And only 1 white wire goes to the switch.
The internal contacts are likely dirty.----Some of those can be taken apart for cleaning or just flush it with some cleaning agent ( alcohol ? )----Model # of the motor?---A 1972 model 85 / 100 / 125 HP ?
Also need to remove the much mis-understood pulse limiter.----Plug that port.----The pulse limiter is a flow fuse for the VRO.---Not needed with the simple pump.
Well----I looked at 2 of these filter housings.----2 of many that I have.----Clearly there are arrows.-----The one furthest from block shows IN---And one closest to the block shows OUT ----So best to look at yours more closely.
