Kelly, my rusty brain cells are sparking back to life. I think you are
right. My thinking at the time was, my primary apex lube will be 2 stroke
mix. But I left the injectors in place at the "minimum" setting as just a
backup. Plus I like the idea of placing oil directly on the apex seal where
it's used. I am religious about putting the two-stroke oil in the gas, even
when travelling where it's more of a pain.

The oil will still flow at the minimum setting, but it's probably not enough
if that is your only apex lube source.

Thanks for correcting me on this.

Perry
