what plugs should i have in a jlo rockwell LR340/2 stroke ,model#338 438,i beleive its an early 70's model

NGK B7ES or B83S is a good start.... I don't have the manual handy, but it's in the ball park. A heat range or two off shouldn't hurt, but I'd lean toward the B7's.....

I went to our local Rural King store and was shocked to find the champion spark plug book had all 6 wheelers listed even the G50b motor
