I’ve recently drained and had the fuel tank out to clean out a load of rust and crap and fit an inline filter under the boot floor. I did filter and refill the tank with half a cans worth of the old fuel I drained out, which should be enough to get it running and to the nearest petrol station.
I had it running briefly for 10 to 15 minutes to check for any leaks etc. It wasn’t running perfect with it occasionally misfiring and running a little rough, but I put that down to the old fuel, but it was running.
I tried staring it after sitting for two days and ever since all its done it turn over and not fire.
So far what I’ve tried.
- Yes there is enough fuel still in the tank
- The float isn’t stuck and float bowl is full of fuel
- Removed carb dashpot and piston and blown though jet which is also clear
- Poured a cap full of fuel down the carb, nothing
- With ignition on, checked for spark at the points, which there was
- With a plug removed, checked for spark which there was but it also tried to fire and kicked back on the starter
- Drained battery trying to start, trickle charged to 14.2 and refitted the next morning holding charge at 12.5.
- Tried staring with the freshly charged battery, turns over but doesn’t fire
- Replaced the coil with a spare known good one
- Ht leads and dizzy cap are all new, as I broke the dizzy cap refitting one of the clips and upon fitting the new cap pulled one of the old ht leads apart.
- Marked and removed dizzy and replaced the points, reset the gap and condenser
Still does nothing but turn over, the plugs are wet and all spark when removed, but then it also tries to fire with only 3 plugs fitted. Ignition timing was set to 8 degrees at 1000 rpm with the vacuum advance blocked and hadn’t been touched before the not starting issue.
