What spark plug do you recommend for 1949 model B john deere

John T · Sep 3, 2010

Pretty sure that takes the newer smaller 18 MM Plug, if so I prefer Autolite 3116 in a NON Resistor (my preference, ESPECIALY if it uses a Magneto Ignition) or 388 in a Resistor Plug which is a tad hotter then the more stock 386 which Id run if it was NOT an oil burner or bad plug fouler and used long n hot n hard under heavy loads. REGARDLESS of plug brands and actually more important to reduce plug fouling is keeping the temp up to 180 and over and not running the carb richer then necessary......

Thats my story n Ima stickin to it

PS if it takes the older larger 7/8 plug then Id run Autoilite 3077
