Hi After reading a post about the points being set at .10 i am in qustion on the new points i put on my 1970 60 hp The book says if setting new points to gap at.12 if setting old points then gap at .10 i set at the .12 and i have a flutter in the motor at take off. after messing with the slow speed needle it still has a flutter when i take off out of the hole.Should i close the gap ? and why would new points be set differentlly then old points. This whole time i thought i may have carb problems. i rebuilt the 3 carbs and i still have that take off flutter so i am thinking timming and points . In the post i read it said a gap setting to wide on points could cause a miss out of the hole .What should i do ? thank you Tony
 
Tony.... Read this over 2 or 3 times if it seems confusing.

(Point Setting Of Battery Capacitance Discharge)
( Ignition Models - 1968 thru 1972)
(Some have points - Some do not)
(Joe Reeves)

The points must be set to .010 but no wider than .010..... BUT in some instances due to a possible slight inaccurately machined crankshaft lobe or a slight offset of one set of points, a setting slightly less than .010 would be required as follows.

Whether the crankshaft has two or three lobes, when setting the points, check the setting of the points on each individual lobe by rotating the crankshaft by hand.

You may find that setting one set of points to .010 on one lobe, then turning the crankshaft to the next lobe, the gap measures .011 or .012 (too wide). This is where you would need to close that gap down to the required .010. A gap too wide can result in a ignition miss when throttle is applied.

Bottom line, pertaining to the point setting at the various lobe locations____ .010, .010, .009, is okay____ .010, .010, .011 is not!
 
ok I get it 12 is to wide. just wonder why my manule says to set the new at 12. i,ll have to close them.that explains why i have been trying to fine tune my carbs with no luck
 
The reason you set new points a little wider is because the point rubbing blocks are new and this allows for a break in of the block. If they are used, go with the correct spec.
