17.5 Briggs Main Jet
« on: May 03, 2018, 07:27:52 am »
I'm not an expert here just rebuilt the head and fuel system for my briggs ohv engine. As usual the thing wants to surge with the original nikki and my army of aftermarket carbs. I'm about to get a set of fine bits and open up the main jet, anyone have some advice for me I'm all ears  :)

This is the type of carb the 31c707 engine uses

pumped to get this new carb, nikki and its clones have not been kind to me. I see briggs sells a ruixing carb now that looks a lot like walbro, must have been a good design
