I noticed that after I stopped my car last night and came back about half hour later to cover the car up I could smell it was a bit fuely.
So i check the carb over in case it was leaking and I could see throught the sight plug the fuel in the secondary chamber was bubbling away (but oddly not on the primary chamber). I thought it was quite entertaining to be honest, so I put my finger over the chamber vent and fuel literally squirted out of the top of the carb via the air bleeds.
Anyway, will a 1/2" spacer stop the fuel from boiling?
The other thing (which may in part be related to the above) is what voltage should I see at the coil when cranking the engine? I thought it should be about 4-5V from the ballast when idling or ignition turned on BUT then jump to 12V when cranking. Am I right in assuming this? If so I need to wire in a jumper wire.
The engine when stone cold can start on the flick of the key most of the time otherwise it will be a right pain. When hot, however, if left for say 5 mins it starts on the flickr of the key, couldn't ask for any better. But if left for say an hour it takes a good 10 secs of cranking to see the engine spring to life. Is that likely to be a result of the fuel boiling in the carb or the lower voltage?
Thanks in advance for any thoughts
Oh btw, the engine idles a bit rich but not excessive at 12:1.
