I would not run that thing bro. At the least get an adjustable fuel regulator and try to turn up the pressure to richen it up. I would not let it be over 13.0 WOT.

Yea, I'm also expecting that my o2 sensor might have shit the bed I'm going to replace that hopefully by next week if that does not solve things the Then I'm going to pick up that regulator from greg.

The plugs didn't look too different from normal, the only thing funky is I was setting them to O.45 and sometimes a month later or so they would read 0.35-0.40.

If there were piston contact, there would be no electrode left.... Think about how hard the piston would hit that weak little electrode, boom, no more.

im thinking it closes up a bit because the tip gets extremely hot and makes it weak, the u have a piston pushing up 200+psi of pressure 849083294723964802374789038749829074323748932089472 times a day, its just bound to bend a little bit
