Stop in for a cup of coffee

Remember just because they start does not mean they are good, They have a bunch of different sections like high rpm, low rpm, dwell etc.

Oh !! OK, so .... sounds like I need to run them down the road and do a hit on each one, this will take some time and fuel experience, so I know and remember to carry a well known good one with me on these test runs.
Thank you Ray.
