April 2, 20197 yr Hi all, it's probably been asked a million times, but I've got no spark. Is this just a simple fix, like points reset, or am I looking at reseting timing? Also is it easier to set points with the flywheel off, or am I creating more problems? Don't want to start ordering too many parts/tools I don't need. Big thanks for any help

Bultaco points/timing is notorious for wandering. Other things to consider. Check and kill button / lanyard by disconnecting. Fit new plug. Check or replace plug cap. Check wiring to coil.
April 2, 20197 yr Author Cheers, I'll give all these a good check over. Difficult to see anything through those little windows on the flywheel lol. Thanks for the advice

April 4, 20197 yr Points and the point gap is a common issue depending Sherpas. - The point gap should be 0,4mm exactly not more not less, - The points should be in very good condition too. The new points made today are not as good anymore as the old ones, try to get NOS. Here especially the material of the small metal bit's pushing against each other seems to be much softer nowadays then before in my experience.
April 4, 20197 yr Author Thanks all, points checked and cleaned, 0.4 gap, opening fine. Big fat spark. Sometimes it's the simple solution. Edited April 4, 20197 yr by zazoo
April 6, 20197 yr Author Update on spark problem. Bike was bought as a non-runner. Points cleaned, carb cleaned, fresh premix, couple of kicks and she fired up. Thanks all
April 11, 20197 yr Hi, glad you sorted it out, but one question. Was the felt wick still fitted ? It needs a few drops of oil from time to time to lubricate the cam that opens the points. If it is missing, or the cam runs dry the fibre points heel will wear down very quickly, ruining them. An often overlooked item !
