[Healeys] popping exhaust

[Dennis Gavin]

I'm hoping the list doesn't feel this question trivial or unworthy but let
me try. I'm still sorting my 63 BJ7 after a two year, frame off, resto and I
still seem to have bugs. When I back off throttle I get loud popping
bordering on backfire in intensity. New plugs & points and my attempt at
tuning the carbs to proper mixture have all been done. Can anyone give me a
direction or is this not an obvious problem? As always, I treasure this list
and appreciate your efforts to help. Thank you.
