Hi All - just finished a top end rebuild of my '93 4.2 LSE.

HGs were absolutely fu.. past their best.
All nicely cleaned, heads acid dipped, checked for flatness, composite gaskets, new valve stem and injector seals etc, cam & followers all OK and clean.

**** thing won't start, Turns over OK, spark at all the plugs, Dizzy wasn't removed so timing is same as before. Compression in each bore.

It coughs a couple of times at first, then nothing. Take the plugs out and they're wet with fuel - even after only 5 - 10 secs of cranking.

Shine a torch in the hole and I can see the top of the pistons are wet. All the connections were tagged & numbered so I know they're in the right place.

Any clues why there's too much fuel?

TIA - Alastair

One word of warning - failing to start and wet plugs can also be a symptom of not enough fuel.
If the mixture is too weak to ignite, the plugs still get fouled by what fuel there is in the mixture. I once spent two weeks trying to get a motorbike to start that I thought was overfuelling only to discover it was the opposite and the jets were blocked.

are you sure you got the spark plug wires on the correct cylinders? It is likely something obvious, are you sure the coil wires are good. On one occasion my Defender would turn over and the fuel pump was running, I was puzzled Id replaced relays fuses etc. I shook the wires on the coil and it fired right up.
