    ???You say it runs at high speed with choke 1/2 way out? It should run too rich with the choke out. Check the high speed orifice plug. It is deep in the hole behind the hex drain plug. It must be absolutely positively CLEAN without a trace of any dirt or varnish in it. But don’t go jamming drills or wires through it. Too big is as bad as too little.
