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

Hi Buckets,

That's great information for the experts!
That the engine is a replacement is telling ...

It may be that the bonnet / cowling is affecting this.
I wonder whether the backfiring occurs with the bonnet removed.

Just a thought.

Cheers
