Briggs spark plug
What is the equalavent Champion, Autolite etc for a Briggs #298809 spark plug?

official equivalent for 298809 is Champion RCJ8
but all Briggs except Vanguard models use Champion J19LM.
The only difference is the Champion RCJ8 uses a 3/4 wrench to tighten, and the J19LM and RJ19LM uses a 13/16 wrench to tighten.
If you can't find a RCJ8, use a J19LM. It should work the same.

J19lm= Bantom height, "19" in the heat range, & 14mm special for lawn mower.
The 2 plugs are totally different in construction & heat range. Champion plugs, the higher the number, the hotter the plug

Assuming you have the owners manual that came with the engine and the part number you gave is out of the manual and based on what I believe you have for an engine (single cylinder, vertical shaft, flat head) then you would use a Champion RJ19LM or J19LM. The "R" indicates Resistor and is only required if you live in Canada.
