Hi!

I'm having same kind of problems at 4500 and after. Its just like hitting rev.limitter but my limitter is at 6500 so it should be the problem.

What might cose that kind of thing. I have tried almost everything; changed plugs, distributor, dist. arm, coil leads. I have tried leaner, richer, more advance, less advance and even dwell setting notting helps.

Where should i start loking answer??

PS: My dist. arm points dist.pin at 35 BTDC

you should start with ststing exact version of ms and code you running, brief explanation of the engine setup including ignition system/etc and most importantly a datalog.

hey this is my buddy's car. after he replaced plugs and wires it was all good. simple stuff eh
