[Roadsters] Still stumped--maybe no more?

[Tim]

I have replaced the plug wires as I was told they looked beat even though I had replaced them last year, I put a new rotor on, cleaned up the cap and ordered new (my new ones only fit a stock dizzy), removed the radio noise condenser as I was told if it is bad it will affect performance, and double checked the timing, plugs and carbs. 

Car seems to run fine until I am, again, at very high speed. Once the engine is totally heated up, I seem to get slight hesitation (missing?) around 80+ mph. After this last run at speed, plugs looked good by the way.

Am I possibly at the top end of the motor's capability at this point? Could this be why I am getting this slight hesitation? 

Can it be possible that my (less than four year old) coil is failing at high temps & speed?

Thanks again.

Tim

When I last ran my Roadster, it was still not running right. I had set the timing,
re- balanced the carbs, and fixed the fuel mixture**. After this, it seemed to be running well pulling strong through all the gears with no ping or misses. Then, at about 75 or 80 mph, it started to do the hesitation/miss thing again it was doing last week (when I was about half way home from MidOhio -- I posted about this as you might remember). Based on what I had read, I figured it was running lean so I pulled off the road (a few times--this was last Sunday) and each during each stop slowly adjusted the knobs and ended up just under a quarter turn to richen the mixture. After the first and subsequent stops, it was again spitting/bucking/running rough; too rich now I assume. I went home, re-set the fuel mixture back to where it was above**. I was still not able to get the spitting and bucking to stop.

At this point it was getting too hot for me, both under the hood, in my head, as well as outside so I parked the car. This is where I am at and have not looked at the car since last Sunday.

When I had checked/"fixed" the timing last week while in Indiana, I do not think I had done it right: The timing light I was lent was of the fancy variety with a setting knob that I must have not used correctly. When I used my light at home, the timing was up over 30 degrees of advance. I am now set at 16 degrees on a de-smogged 70 1600 running a GB EI dizzy.

Any thoughts please.

Thanks
