Briggs carb help needed

Recommended Posts

pbrenner70
I've got what I think is a 7 hp on a VC Walker. I set the mixture screw one and a half turns out, and the idle screw 3/4 a turn out like the manual says. The problem I have is; It "hunts" at idle until I have turned the idle screw out approximately 3 whole turns but then it makes the mixture too rich for the higher rpms. Is there something I am overlooking? The bowl is set correctly. There is no vacuum leaks. I was questioning the governer springs because the manual says there are two (one big and one small set on the first and 5th holes) but mine only has one that is set on the 3rd hole. Could that be the problem? Thanks, Paul

I think you may be onto something with the govenor springs. Id get a new spring set so there is two springs like there is supposed to be. That sounds like a good place to start. Good luck, Ryan
