Model A backfires coasting at any speed severely. Any ideas would be appreciated.

It has been timed. Float has been adjusted once or twice. It's a wonder the muffler remains on the car. Thanks for any ideas.

Model A's always backfired, and with this garbage for fuel today it is worse, you can try rejeting the carb slightly leaner and running high octane fuel, add some lead substitute, might help but they all did it.

Also check for exhaust leaks in the manifold.
