Barracuda plus 3 horse power Tecumseh engine correct spark plug

Hey there team ice shanty...need to verify if someone can tell me the correct original spark plug for this auger.  I feel like it has been messed with quite a bit before I got it and I changed the carb but unsure it has the right plug.  What is in it now is a champion RJ17l M.  Thanks!!!

Thats the correct plug but i would cross reference that to a ngk plug.ngk runs better in 2 cycles than champions.

thanks!... i have seen the NGK B4LM but others as well...does that sound right?

[DR.SPECKLER]

Br4lm or b4lm will work.its just one has the screw off top and the other is fixed.r stands for resistor I believe.

I'd stick with the B4LM gapped at .030
