Hello,
I've been trying to narrow down a poor running engine and found a scratch in the cylinder wall further down in the bore. I can feel it with my fingernail but its not too obvious.
Could this little scratch be the reason why i run so poorly?
Leakdown test was good
Compression : 90psi - cold w/ a little oil in cylinder. 67 psi cold w/ no oil
