Getting Too Clever I think? Dwell Angles

Had some Halfords gift vouchers for Xmas, burning a hole in my pocket so i bought a gunsons uni-t multi meter - it does all usual elecy stuff but also has a tacho and dwell reading.



Dwell - here lies the problem,



My v8 has a lumination electronic ignition, it runs ok but im sure it could be better but i suspect proplemss with the carbs more than anything - however, I measured the dwell angle when running its 31.9° - the haynus manual says 28° - can anybody explain? can i adjust electronic ignition, do i turn the dizzy? etc etc



Thanks

if it's an electronic distributor, then you can't adjust dwell. Dwell is the ration of points-open to points-closed, and only applies to points-based systems. If it's points-driven (i.e. not standard LR) electronic, then use the dwell meter to adjust the points (for which on the 35D8 distributor there's a handy external adjuster) to the correct figure.

if you don't have points, the only adjustment inside the distributor is the pick-up air gap, and that shouldn't need adjusting.

rotate the distributor to adjust timing, noting that on some engines the best figure is not what the book says.
