Having got Ruby back on the road and put a few miles on the clock, I have been trying fine tune the timing?
Using a strobe light it is pretty evident there is little or no advance taking place with increased engine speed. At low revs the corresponding marks on the pointer and pulley remain pretty stable under the strobe, but the mark on the pulley becomes anything but stable, very erratic, fluctuating up and down as revs are increased.
Having read the comments on this thread, I wondered whether the use of electric ignition was worth considering?
So following Ruairidh’s comment I checked the resistance on my coil, which is the original, and this gave a reading of 2.1 ohms, I then checked a new unused coil I carry as a spare and this gave a reading of just 1.6 ohms.
So I assume using electric ignition would not work without another replacement coil as well as new leads and would be folly to use my current distributor with just a conversion kit ??
