@RevISK and I are not advocating in buying a Snap-On or similar product one might find with professionals, something at Scamazon for 50-80 bucks works for us shade tree, yuppie brew mechanics. My experience and opinion is one that has both timing and tach reading for me is invaluable as several times a year I will check both engine and carb. And, not trying to convince anyone of anything. The setup works for me, and only sharing my experience. Opinions are worth what they cost, nothing.Key point here.
Some of us are shade tree at best, hobbyists as a norm.
The $80 timing light I have, to me, is very useful as I can set (and know) the advance while watching the RPMs.
I’m a professional photographer and will tell you that the best camera is a stripped down 35mm Nikon with no light meter, no auto anything, a 50mm lens and sack of black and white film. However, a weekend warrior who doesn’t innately know the circle of confusion would really benefit from a camera with bells and whistles. It really helps to teach the principles.
