Hey,

I have just overhauled the carb on my 4PT and after putting it back together and fitting it I can´t get the bike to run. It has also been sitting for six weeks so it might not be the carb although this is the most obvious thing. Am sure I have done everything correctly and have also shown it to a mechanic who had a quick look at it and said that its ok. However, when I open the drain screw at the bottom of the float bowl nothing comes out. I have checked the fuel taps and made sure they´re on. Does anyone know if this is normal? I would have expected fuel to run straight through if you have the tank taps on and the drain screw open. It just occured to me though that maybe you need a certain level of fuel already in the float bowl for the fuel valve to open because with it completely empty the float will drop right down and close the fuel valve. Any ideas greatly appreciated.

The other possibility is that there is no spark for some reason. The battery is fully charged though and it has a decent plug. Does anybody know a way to test the coil. I remember when I owned a VW bus that there was a way to test the coil by holding the HT lead slighty away from some metal and turning it over, but I don´t remember exactly.

Many thanks,

Finian
