As I mentioned in my previous posting, my green XL would not start not matter what I tried. It was going fine when I parked it in the garage but I had not started it for nearly 2 weeks. I was sure it was an electrical problem so in the course of trying to sort things out, I put in a new set of points, tried a different coil & condenser, cleaned the plugs & still no go. There seemed to be a good spark at the dizzy & at the plugs but even despite pouring some fuel down the throat of the carbie, it still wouldn't start.
Time to consult Dr Google & my neighbourhood expert. Kevin, my good neighbour who knows everything about classic cars, came & we went trough all the possibilities. He felt that the problem was lack of fuel & by testing the flow of petrol from the inlet hose thought the fuel pump may be the problem.
I think that I replaced this pump when I first got this car but it didn't take long to take it off-just the two bolts.
I undid the 6 screws holding the pump together & found that all the parts seemed in good order with the diaphragm intact with no splits or problems. In fact, it was in pretty good condition. I did replace the O ring as the original one seemed a little stretched. Then I just screwed it back together & refitted the pump.
To ensure that there was sufficient fuel in the carbie, I attached a hose to the inlet & with a small funnel, poured in about a quarter of a cup of fuel. Then, I reattached all the fuel hoses to the pump, filter & carbie and crossed my fingers in the hope that it would start.
One quick turn & it fired up straight away & ran like a charm! What a lot of stuffing about!!
My advisor also suggested that the carbie float may have become stuck (due to little use over the last few weeks) & thus not allowing fuel to enter the carbie.
Whatever, it is back to normal & running well as it usually does.
It is all good fun - well sometimes!!
