Hi Guys,
The thing could be running rich. Since I haven't a clue what the previous owner did, I think a carb adjustment is in order. Hey Verell, want to learn about carbs? ;-) I'll ask my local hot rod expert if he can do carbs on this thing.

The ignition is stock, dual points/distribs.

In the meantime I'll try John's clutch technique to reduce ambarassment!

Thanks!

Jonathan

To avoid this, I usually slow down the engine to 600-700 RPM with the clutch prior to turning the key off.

Jonathan,
Running rich may also explain the condition of your orig. plugs. I think you mentioned they were vy dark w/some carbon.

BTDT. Are you running stock ignition or an aftermarket unit (like the Electromotive)? Many of the newer systems fire the ignition on all strokes.

Second, if your idle mixture is too rich, they'll do this.

Net, tune the carbs, it'll go away.

Hi Everyone,
My 77 GTB runs fine, but when I turn it off, it backfires a single time just as the engine dies. It's a little embarassing at the supermarket, especially when people start ducking for cover because they think they are being shot at. Anyone had this issue? What gives?
