I'm in the final tank of breaking in a TR non-turbo engine.
What options do i have to use on this engine? It came w/ an OS
A5. I'm using a used OS #8 i had in my pit box cause the A5
died after 10 tanks into breaking. I want to buy some spares
before the weekend. What other options do i have incase
my LHS doesn't have A5?
THX,
