Yeah me again - aforementioned Uno 45 FIRE has another weird problem which I haven't seen since I jetted-up the idle (see other post) yet I don't think it is fixed (somehow).
These events have happened:
- (1) Car starts up and drives 1.5km down road
- (2) Car grinds to a halt, engine power gone (as though ignition turned off)
- (3) Check for spark - good spark
- (4) Take off fuel pipe and crank engine, engine starts, put pipe back on, drive off for 200km round trip without problem, plus five more weeks happy motoring until...
- (5) 1, 2, and 3 above, then take off carburettor top to find carburettor full with petrol to correct level. Replace carburettor top. Engine starts immediately and runs OK for a week - but how much longer?
I don't think it's a fuel problem (carburettor has been changed between 4 and 5 plus cleaned out for the umpteenth time in search of idling problems). So my best theory is that the ignition module has been overheating while trying to fire an overly-weak mixture. Somehow, step 3 wakes it up again.
Between 4 and 5 also have taken apart distributor, checked pickup wires, cleaned connections, and set air gap correctly (it was about three times the correct amount, though of course changing that made no difference).
Interesting though isn't it... any ideas? (Monty Mort I am looking in your direction
