Case 411B Spark Plugs

Could one of you tell me the correct spark plug for a 411b gas? Thanks in advance - Bob

The original plug was Champion D16 which is now sold as p/n 516.

The cross-over plug in Autolite is 386, a much better plug in my opinion.

Just a quick question Joe, or anyone for that matter, but I have a set of autolite 388's, would they be the same but hotter. Question is would they work? Thanks again - Bob

The 388 is the same plug as 386 just hotter. It is a good plug for light loading and idling. Probably not the best for sustained heavy pulling, plowing, etc. Note that 3116, some of the guys here like that non-resistor plug for the 148 cid engine.
