i have a 1968 Bug...it back fired and now wont start. Gas to carp is good. Sprayed starter fluid. Have not checked spark. Going to tomorrow. Could it be jets or rings? d
If you used starter fluid and it didn't even hit once the chances are high that you don't have any spark, backfiring can be caused by a failing condenser, so replace the points and condenser and then check for spark.
