http://www.oldminibikes.com/forum/attachments/briggs-stratton-engines/35885-getting-2hp-run-photo-2011-11-06-11.06.jpgi have a 2 hp engine that will start turn over and has a spark, i have had it going but doesn't want to keep going. any good suggestions as i am a greenie on these type of engines.
That's a Vacu-jet carb. There's no diaphragm. You can tell the difference by the choke handle. The Vacu-jet has a horizontal handle, the Pulsa-jet has a vertical handle, and has a diaphragm.
So, drop the tank and make sure the pick up tube is clear, and remove the mixture screw and with aerosol carb cleaner, make sure that is clear as well. Initial setting for this screw is 1.5 turns out(gently tighten all the way in, back it out 1.5 turns). With the engine running at approximately 3000 rpm, turn the screw in until the engine looses speed. Then turn the screw out until it begins to run unevenly. This may seem too rich, but should perform well under load.

og35891,
Mini motors is correct. What you have there is a nice little 2HP Briggs with a Vacu-jet carb. I have worked on both the Briggs pulsa-jet carbs and vacu-jet carb numerous times. The vacu-jet carb is a very simple design and sounds like it only needs a real thorough cleaning with carb cleaner. Also, make sure your gaskets are in good shape otherwise they should be replaced.
Heck, I picked up this vacu-jet, gave it a good cleaning, and it ran great on the engine.

The Ruppster is exactly correct about the carb gaskets. As the name of this carb suggests, it uses a vacumn created by the moving engine piston to draw air and "pull" gas up from the tank and into the carb. If there are air leaks anywhere in the system it will not pull the fuel up properly or even at all. Check the gaskets at the tank to carb and at the carb to engine. If any appear bad, or if you have any doubts- replace them.
I wonder if "Golden Boy" is a Briggs thing. Cause if you compare both pics, it looks like both are the same. The only other answer is that they both were on an edger.
*edit. I just Googled Golden Boy, and nothing(relavent) came up. But by adding "edger" to it, the Golden Boy edger came up. So, there's that answer.
