- Hi folks. I've got a very high compression MGB. Therefore, I've been using premium California fuel (91 octane) & using an NOS octane booster to keep my B from pinging under load. It's been working pr

- The orange color is not known to me, but the lack of power @ higher speed looks to me as fuel starvation. Possible causes: fuel filter clogged fuel pump failure clogged fuel line carb malfunction Che

- I bet the orange deposits are from the octane booster. How high is your compression ratio? My 67 Barracuda with 10.5:1 compression runs on 91, retarded 2 or 3 degrees from spec. I found octane booste
