Thanks bigted, that has improved the clarity of this thread, and given it a better chance of being a useful archive. I agree with you the problem is probably the carburetor, but have been aiming to go through the standard process (check spark, compression, fuel) to give Funzo the best opportunity not to get into this situation again. The remaining steps, once he verifies that the throttle is open when the speed control is in the start position, are to check compression, then try putting a spoonful of fuel directly into the cylinder. If it doesn't start at least briefly when he does that, it will be time for a new spark plug. On the other hand if it starts then stops, it will be time to begin again at the beginning on the carburetor process, this time step by step. This is my universal "anyone can do it" investigation sequence for a non-starting Briggs, and I think Funzo is not the only member it can be useful to.
From the workshop manual, it seems to me that Briggs treats the Pulsa-Prime as a throwaway carburetor. They tell you briefly how to clean it, and that is all they have on it. If that doesn't work, you are supposed to get a fresh one.
