[mb911]

How many miles were on the new sets when they failed? Is it possible that the phenolic wore down as they were breaking in and then the problem? If this were the case the points must have been misadjusted from the getgo. I can tell you that my points in my 914-6 conversion are perfect since new and that has a 2.7 in with bosch points. Are the installers using the supplied lobe grease that comes with the points? That could also be the key. Just some thoughts. Oh yes my problem appears to be unrelated to ignition think it is fuel pump.
