Scott,
I'm assuming the particular dwell meter you have does not have a "4
cyl" setting,or scale.
You can use the "8 cyl" setting/scale. Just double the meter reading.
Ie. If the meter shows 25 degrees, thats 50 degrees on a 4 cyl.
Craftsman makes a very good dwell meter, as do most of the major tool
manufacturers. Generally speaking, the name brand tools are pretty much
the same.
Oh, when you go to buy one, don't get pulled in by the ones that will
check all the other electronic bells and whistles. The MG ain't got'em.
Just stick with a simple tach/dwell meter.
I'd recommend the brand I use, but believe it or not both of my meters
are USAF surplus!!!
