Steve:

Coupla things...The car did this when I got it a year ago and never

stopped. The carb was replaced because it needed to be, not to stop the

break up. I was hoping that a side benefit of replacing the carb would

have been fixing the break up as well. The tune up was done by my

friend who has owned a repair shop for over 25 years, is good at what he

does and owns a 67 small block Corvette himself. We changed the plugs,

points, condenser, cap, rotor and wires (and all of the filters too, of

course). We set the dwell angle and the timing and checked the advance

at high RPM. According to the receipts I have, the distributor was

re-curved at some point in the past. I assume that was done to properly

match the cam that was put in. After all of that, it was still breaking

up. When I changed the carb a month or two ago, like I said, I was

hoping it would fix ALL of the problems. It runs a hell of a lot better

with the new carb and makes 100% more power than it did, but alas the

breaking up persists.

You were suspecting the coil in your orig post, so, when the guy did the

tune-up and ran it through the scope, what was the max voltage output of the

coil? Was he getting a clean firing on the primary side pattern? Does

that dist use a ground wire from the breaker plate to the dist body? The

scope should show those things up, but a visual on them never hurts. The

tune-up process checks those components not replaced in the tune-up for

proper operation. IMHO, you don`t need a higher voltage coil than the car

was equiped with. It didn`t leave the factory breaking up at high rpm and

the coil only puts out as much voltage as req`d to overcome the resistance

in the plug and wires, so how much you have in reserve above that amount is

of no cconsequence.

We never put a scope on it. The only scope he has was put out "in the

trailer" a long time ago. 99.99% of the cars he repairs are equipped

with advanced diagnostics (OBD II) so the scope is useless. He`s been

saying for a long time that he should drag it out and see if it works,

but he`s been super busy for a good long stretch. It`s great for him

because he`s getting an incredible amount of new customers every month

and not losing the old ones. I just have to wait until there`s a lull

in the action.
