Soundline Posted June 22, 2018 Author Report Share Posted June 22, 2018 Interesting, this is exactly what I was looking for. Now back to the series of issues I’ve walked into.... because... I did something that’s probably stupid. I pulled the plugs and they’re a different model of NGK than what I put in. I’m headed out to a friends place now and I started thinking, “why” are they different? 3 options, all equally likely. I bought the wrong plugs, he bought the wrong plugs, or we both did. I’m putting in NGK BR6ES 4922 gapped at .028. I pulled that number from the FSM... but it’s not the stock L16, it’s an L20B... He was running BPR6EY (unknown) gapped at >.030 because that’s where my gauge stops. My educated guess is .035 - .040. Fixed the cracked fuel line, new Accel cap/rotor and NGK wires. Radiator should be done today so I’ll get it all back together and see what happens. In the meantime, check my math and heckle away. Thanks guys, seriously. Quote Link to comment
Crashtd420 Posted June 22, 2018 Report Share Posted June 22, 2018 There's not much different between those plugs.... both have the heat range of 6... The br6es has a nonprotuding electrode The bpr6ey have a vgroove and a protruding electrode.... Quote Link to comment
Crashtd420 Posted June 22, 2018 Report Share Posted June 22, 2018 And Ngk says gap for the br6es is .036 Bpr6ey was .032.. . Quote Link to comment
datzenmike Posted June 22, 2018 Report Share Posted June 22, 2018 Points run about 0.032" If EI you can gap much higher at 0.043" because of the higher voltage. Be sure your wiring, cap and rotor are in good shape though. A wider gap is harder for the spark to jump and it will look for an easier path to ground. If wires cap and rotor are good there's no problem as the spark plug will be the easiest path. Quote Link to comment
Soundline Posted June 22, 2018 Author Report Share Posted June 22, 2018 Wow... so I am stupid... there’s a fourth option of them both being correct. I just pulled out my other gauge and the previous plugs were gapped between .036 and .046. This might also be some of my problem. That’s a pretty wide variation. Well see. With the collective assistance of you guys and Gato I’ll get this beast on the street. Quote Link to comment
