TR3@70mph engine seemed to "flatten out" or.....
flutter like it wasnt getting enough gas? ....ran good at all other speeds...took it up to 80 mph to see if it would happen again and it did. I've been doing plug cuts to check the new NGK plugs and they have been a nice grey colour(was running rich with the Champions) I've leaned out the carb mix a little to achieve this.I'm running a header,TR4A intake manifold and mild street cam. I'm wondering if for some reason I'm not getting enough fuel at high speed because of the mods?. I have an electric fuel pump set at 2.5 psi and a newer generic inline gas filter(too restrictive???)Also... could this be a Pertronix issue???
