So, my magnum was running fine. I don't know why, but for some stupid reason I decided to replace the old worn down points, so I put brand new points in, set the gap and the timing to what it was before, and suddenly it started four stroking on the low end, and it wouldn't idle...just from changing the points!! The top end remained the same, however.
I have since replaced the stator and the coils, the condensor, the high tension coil, and I've tried 3 different sets of points, including the original. I've wrapped every inch of the ignition circuit in electrical tape. I've tried many different point gaps, from super wide, to barely opening, and I've tried different timing advances, from .8mm to 1.2mm to 1.7mm all the way up to a little over 2mm btdc.
Nothing changes, no matter what I do; same lack of idle, same 4strokey low end:(
It should be noted that I'm running a leaner jet now than before I changed the points and all this trouble began, so it's not that.
Please!! If anyone has any ideas, They would be suuuuper appreciated.
