15 horse Johnson 2 cycle, new fuel pump last year, did a service on it a few months ago getting ready for the fishing season. Went out today and it started right up, idles smooth but when I throttle up it acts like it runs out of gas. I pulled the choke out and it ran enough to finish the trip but as soon as I let the choke in, it would stall. The carburator has not been removed or cleaned. Acts like a vacume leak since it runs with the choke out. Anyone have an idea as to what to look for?
thanks in advance.
