JACK M Posted June 10, 2015 Share Posted June 10, 2015 An exhaust leak can cause back fire on deceleration.And yes, a lean condition or vacuum leak could also be the cause. Link to comment Share on other sites More sharing options...
RWPerry Posted June 10, 2015 Share Posted June 10, 2015 When my 1925 did that it was because of running too lean. A little adjustment and it ran fine. Link to comment Share on other sites More sharing options...
