Hi Tyler, MW and WG,
I've encountered a problem with my magnetron Briggs on the Supa Swift 767 Standard.
After a while of mowing it's hesitating when you try increase throttle.
I'm thinking it may have gunk all over the engine cooling fins. I watched a video servicing a stihl trimmer and he said grime can act like wearing a jumper and reduce cooling efficiency.
Will have to remove the cowl and have a look.
