On piston engines the excess lead does not show up on
plugs. That's why he doesn't refer to it. I sent him brief note
encouraging testing with rotary, as it would be good test of his new
formulation. Either you or Perry would be great test cases. Perry
because he is so much more sensitive to lead.

I didn't see any mention of compatibility tests with composite tanks.
Just that it's "formulated with an environmentally friendly solvent".
He seems to be a conscientous supplier, but I do know enough about
chemistry to know that I don't know enough about chemistry.

I'll try to contact him to see if he will send me a sample. I burn
100LL so rarely, and I have to burn it almost pure for 4 hours before
the problem shows. Who wants to buy $4.50 gas when $3.00 gas is
available anyway for local flying?
Like Ed says, the TCP doesn't work at water-cooled engine temperatures
and I verified that last summer. I also think my lead fouling is
related to the rotary spark plug design (it's very different than most
spark plugs) and that I'm running rich. Maybe there is a different
spark plug design that would be less susceptible.
I now have a set of BUR6EQ/BUR8EQ "hotter" spark plugs from Mazdatrix,
I think they were only about $9 each. Will try those someday. Ed, maybe
you should get a set and try them since you burn 100LL all the time.
Their life might be shorter?
I'm now commuting to work everyday by airplane, it's a wonderful way to
go!
