OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines B&S Vanguard 20hp V Twin - Backfiring on Shutdown

Hello Buckets

That's a great question.
It may be that it was recommended in hotter climes where backfiring
might occur in hotter ambient temperatures.

Hopefully, a Briggs expert will be able to shed some light (heat)
