My Briggs is in need of some lovin...
Seems to pop or back fire through the carb when you bring up the revs...
Are there a few basic procedures i need to address to get it running back the way it should?
If valves need adjusting, how is it done?
Plug is a motorcraft A7NU which i am havin trouble finding. Is there an equivalent ?

Cheers....
