I'm hoping some of the clever/experienced froggers can assist me in getting my R10 started. I took it for a 5km drive around the suburb and then parked it in the garage. it was running beautifully, no flat spots or misfiring and it never overheated. When I came to start it the next weekend, the starter spun the motor with no problem, but it would not fire.
The electric pump is pumping good, I've checked float level, blown out jets, and the pump jet can be seen pumping. I then turned to the ignition and noticed that the spark at an earthed plug looked rather weak. I fitted new points and condensor, but no change., so I replaced the coil with a new (no ballast resistor) Bosch coil, and replaced the ht lead from coil to distributor, still no luck. There is 12.8 volts at the coil, which drops to 10.8 volts while cranking the starter. According to an article I "googled", this is suffficient as the coil will pump up the voltage to about 300v anyway. I've re-set the points, re-set the timing (static) and checked that wire from condesor is not earthing inside and outside of distributor. I've even disconnected the rev.counter to eliminate the possibility of a short there in. I keep the battery fully charged and there is no problem turning over the motor. The spark plugs have only done about 300 km. I even tried putting a 12v supply direct from the bat. to the coil, all to no avail.
What could have possibly gone wrong between switching off, and trying to re-start one week later? Starting fluid doesn't help. No one else has been near the car. PLEASE HELP!
