I need some help with carburetor kit or whole replacement for this vintage Kawasaki blower. I have it running but it runs real rich. Yard sale find. Looks like someone tried to rejet it by soldering holes closed in nozzle and redrilling it. It's a mess. Anyone know where I could find replacement nozzle or if need be the whole carb. I can't find anything but a few pictures online of the unit. No info on carb. Looks like a real nice old engine. 25:1 it says on the gas cap. Getting plenty of blue smoke when running at that ratio. Only revs up and smooths out after I shut gas off. Smooths out for 4 or 5 seconds before it runs out. That's what makes me think it running rich. Try to attach some pics. Thanks in advance for any help.
