so then, this is a single cyl Vanguard? It sounds like the one that I put onto my Swisher trailmower.
Yeah I bought that overpriced $60+ kit for the Mikuni on mine, fortunately that was all this one took to get it to run right, it too did the same as yours when I 1st started it up...(actually somehow $86 sticks in my mind for that kit, that may have been with the new air filter too, though it has been over a year ago since I bought those parts) I know that I got mine from Pat's small engine, a mail order place in Minnesota.
I know that mine sat for at least 5 years, if not longer before I got it, and 2 years since I have had it. I kitted mine last year and ran it just long enough to warm it up good once, right afterwards, with gas that was treated with Sta Bil/ in case any fuel residue was left behind. then I shut the valve off at the tank, ran it til it died from lack of fuel, and pulled the drain screw from the corner of the bowl.
there is very little in that kit, for what it costs, too! Considering that, I make sure to shut the valve off and run it out of fuel every time that I run it.
I have mostly seen Mikuni on motorcycles, I wonder if you could cross that Briggs number and do better on the kit or a new carb from a motorcycle parts place? Just like the old Walbro's on Tecumseh engines, it was always much cheaper to go directly to Walbro for those parts.
does yours have direct engine mounted choke and throttle controls? Mine don't; and I hunted all over to find what I'd need to convert to that setup, came up empty so I had to fab up a control panel to mount remote throttle and choke controls, my throttle cable is all of about 4" long now.... that throttle slide will not stay at full throttle by itself for more than about 1/2 a second by itself...
seems like a strong engine, runs quite smooth and really starts easy, once the carb gets gas again it's about 1/2 a spin off the starter, to running... this is my 1st Vanguard. From what I hear, they are supposed to be one of the better lines of "newer" Briggs engines.
