5k rpm limit and cutting out

Sorry to bust in here with my first post, but i have a mk2 escort with exactly the same problems. will rev to 5k fine, and 5.5k with much determination but doesnt make any power up there.

After replacing the carb, having the distributor curve adjusted and replacing all the vac hoses im now guessing that my cam is too far advanced. possibly the same with yours?

It is my understanding that a engine with an advanced cam will move the powerband down in the rev range, but will required alot of advance to run. I notice with mine that it makes better power at partial throttle where the vac advance is actually doing something.

just a thought however, perhaps your cam was actually dialed in, mine wasnt

is it possible my electronic ignition needs a ballast resistor and is getting too hot? i noticed today the plugs attached to my coil which have polycarbonate sleeves have all perished and they are brand new...

Well it appears that I solved the problem and of course it's Mildy embarrassing. Engine had a poor earth back to the chassis which allowed it to run but the resistance must have gotten high due to heat or some such thing and gotten worse with higher current. Now it has an earth strap and goes like a champ

I just had it checked for a cert today and I'm waking to hear back from Clint on one of the items I need to fix, pretty close to wof time though. Once done I intend to drive down to invercargill for a good road trip so I'll come see you and a mate of mine that lives down that way. Also will likely enter some events for a laugh
