<p><tt>A few years back there was a bad run of ignition rotors
released that fit many Brit distributors. They would develop a
spark path from the contact to the post grounding out the high
voltage stopping the engine. It was so bad that I had two fail
and then carried several spares. I ended up handing them out to
three friends that had on the road failures. I finally found
another brand that didn't have the problem but the name on the
box has nothing to do with who made it. However it seems that
the one made by Airtex/Wells (RockAuto 4R1187 $3.45) was
different and has worked well. Now this may have nothing to do
with your problem but the symptoms are similar enough to mention
it. Good luck!<br>

<p class="MsoNormal">I?ve seen the coil fail intermittently,
seems fine when cold, but fails when warm. You have coil
mounted on inner fender or bracket (like 1600), right?
Unlikely all plug wires would fail at same time, but, if the
coil wire was bad?</p>
<p class="MsoNormal">Have you checked spark once coil heats up?
Weak coil possibly producing a weak or no spark when hot?</p>

indicate something in the electrics.</p>

style="font-size:12.0pt;font-family:"Times New
Roman",serif">While on a long drive in the hinterlands
of KY in my 1960 MGA with a 3-main 1800 MGB engine, I nearly
ran out of gas after about 170 miles that day. I found a
gas station and refueled (the gas had alcohol and I usually
run non-alcohol gas). About 30 miles later, the car started
to lose power and then quit. Figured it was a clogged fuel
line, but fuel was pumping out of the fuel line at the rear
carb and there was gas in both float bowls. Cleaned out both
float bowls. Had spark from the coil and to all plugs. Had
just replaced spark plugs and gapped them to spec two days
previously. Regapped points (1 year old 25D distributor).
Nothing. Sprayed starting fluid in the carbs. Nothing.
Locals towed me back to town. Locals played with wires under
the bonnet at the coil as I politely batted them away. As a
last ditch effort, I advanced the timing and it caught at
high revs! Drove a few miles, but lost power as I
accelerated and stopped. Stripped and reattached coil wire
to harness. Started, drove a couple of miles, faded, and
stopped. Towed it home. At home, it started reluctantly.
It drove for a couple of miles and it faded and quit. Gas
in rear carb float bowl but no gas at the front carb float
bowl. Blew air from fuel pump back to gas tank with audible
air flow at the gas tank. Replaced the float bowl needle
and seat at the front carb. Fuel pumping nicely at both
front and rear carbs. Have spark from the coil and to all
plugs. Static timed. Nothing, doesn't even try to catch. I
do not have a fuel filter other than stock sleeve in the
fuel pump. No odd sounds. I am stupefied ( except for the
possibility of clogged jets, but if so why wouldn?t it start
with starter fluid). If it is the coil or condensor, why am
I getting spark? Why would advancing the timing get it to
go at such high revs that one time, but normal timing gives
you nothing at all, not even a spit? Do I have a cam flat
spot problem? How have I angered the British engineering
gods? Any hints or diagnostic suggestions? I have also
posted to the MG experience folks</span><span
