New Plugs - Harder Cold Start?
in 912 / 914 Technical Questions
4 years ago
I have an older 914F engine, black starter motor, old style ignition packs. Fresh fully charged battery. During a repair last summer the plugs were changed out to new style 297-656- three electrode fixed gap (.031-.035)
Seems like this winter i am having more difficulty with cold starts compared to old style plugs x27EPR-U9 set with MINIMUM gap .027 per LMM.
Is this my imagination or are other having cold start issues with new plugs?
