Quoting Removed, click Modern View to seeWell, it is back there sometime yesterday, at least in Modern View, but here it is again:
" While you have everything hooked up, do everybody a favor, if you would, and put your scope V input on the black wire going to the distributor and snap a picture of the points opening with the condenser installed and without. Might give everybody an idea as to just what it does to protect the points from pitting.....Thanks. " I would do that, but I did all that back in the winter of 2007 & now on this July in Texas day, it is just too darned hot to get out there. In my notes that I made at the time, however, I see that there was little difference in the voltage appearing across the points with caps from 0.01 to 0.4 microfarads. What is clearly visible is the amount of arcing at the points. The least with a "factory" value of 0.2-0.3 & increasing with larger value & increasing a large amount with much smaller values until the greatest with no cap at all. With no cap at all, the HV spark is weak enough to cause missing, but the ring up voltage spike remained more less the same voltage. I believe, because, voltage of 'inductor' will still rise to whatever is necessary to establish an arc at plug. Clearly evident however, is the loss of energy that is being burned up/dissipated in points arcing and this is seen as greatly reduced duration of plug arc time (from 2.5milliseconds to 1 millisecond with no cap). As a side note, one of our 8Ns will not run with no cap.........must be marginal?

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
