I have all the information you need and lots of parts to help you get it running, as far as spark plugs I like to run NGK AB6 spark plugs, your carburetor is updated it originally had a Johnson carburetor yours has the Vacturi AO500 with an adapter much smoother running carburetor. Main thing I have to concern yourself with is the crankshaft on these motors have to make sure that there is no major pitting on the crank pins ….😎
