I've always static timed generator shovels and they run fine. I recently adjusted the points on a '72 and when I checked the factory service manual, it said to set timing on the retard Mark when static timing. It also said that this is like an emergency/ side of the road setting and that it should be set on the advance mark with a timing light ASAP. I haven't ridden it but it starts and idles fine on the lift. I've ordered a clear timing plug as I've never owned one.
The question is whether this warning in the manual is justified. If set on the retard Mark properly, is it that far off? Seems pretty close by ear. Thanks in advance.

 

Set the Cone bottom to Advance mark with Points ... I always do... same as my '68 near as I recall!!!

Of course with the Mechanical advance at Full advance... and a Note; While they run set to the Retard Position... Retarded timing results in excess heat...

Think about it.... setting at the Advance mark with the mechanical advance at full advance... is Fool Proof!!!

 

Thanks Race that's what I do on the flatsides as well. The question is more rhetorical in why does the manual make an issue of setting it on the advance mark with a light ASAP.

 

Good Question... My Manual don't!!!
What is the Published date on yer Manual??? Later is more Safety ****... IMO
Fear not... yer gonna be just fine..

 

It's a 1970 to Early 1978 manual copyrighted in 1978. Your advice is how I time the flatsides. I'm going to wait until my clear plug arrives and time it with the light and see how much it's off. Remember buddy in high school timing his Sportster with a shop rag over his head to keep the oil off. Don't need to go there.

 

I havent owned a timing light since before I was drafted...I don't feel Inferior... LOL

 

I get that just have one since the ‘60s. Use it on a BMW. No oil shooting out on that bike.
