View Full Version : Setting points on an older 40hp

09-20-2006, 09:58 AM
"Hi there, could anyone offer some advice as to the proper method of setting the points (contact breakers) on an older petrol, twin cylinder, yamaha 40hp electric start.

The gap is 0.0014 I am told but as to the method of setting I am lost.

On the flywheel there are two diagonal marks, one is simply a line the other is a line with a V coming off the end.
I dont know what cylider is number one and which is number two either.

Any help would be very welcome.

Regards Alan in Scotland"

"u need to find the points first
u need a feeler guage
u rotate the distributor so the points are fully open, the put in the feeler guage and then adjust

i would switch over to electronic ignition
like pertronix or a crane system"
