I have been playing with the Marvin today and sort of hit another block. He is only running on three cylinders no matter what I try, its cylinder number 3. What is very daft is that I cannot seem to get a spark to number 3?
I have cleaned and changed the plugs around, changed the leads and cap with no avail. Then I played with the points and again still get a good spark to 1 2 and 4 but nothing to number 3?
I came in for a coffee and some reading via Google and started to get worried as people suggested it was gaskets, valves burnt out, heads warped and all sorts of snake oil ideas, but all of these mechanical issues are red herrings, as when I pull the lead out of number 3 and push a spark plug into it and earth it on the block I still get nothing, so its not the lack of compression in the block or a duff plug (swapped them around remember) its a basic lack of power to number 3?
I went back out and started a fresh, re set timing, check the caps and leads, cleaned the plugs again, made sure the leads were set up anti clockwise 1 – 3 – 4 – 2 , all were fine. I started the car and it fires up straight away, but its still running on three cylinders only.
The only good news so far is that the black smoke form the Webber days is all gone, and the exhaust is back to its normal clean outputs, so the Solex is so much better for it.
In other news checked on the GT, all is well, put all the metal panels I have collected over the last year and bit in the garage so I have space in the shed now.
