MASSIVE spitting....... where am I going wrong?..........
Posted: Mon Jan 29, 2007 4:53 am
Hello again.
Now that I have the ignition working, I am getting major spitting out of No4 carb, light spitting out of no3 and none from Nos 1 & 2. Not with the engine iding, but at constant revs. Less on blipping but still there. I have seen flames in the throat of No4 on occasion.
It seems strange that I only get spitting out of the back carb.
My colourtune is telling me that the carbs are rich (will not weaken off to a blue flame). On pulling after idle the plugs are very sooty. The car will idle fairly well, and will do so with much more advance than I thought possible. I know because I started it that way after reversing the rotor arm.
Does anyone have a list of jet sizes that works in the real world with 30mm chokes? Probably arrived at after much experementation!
I have nearly all the bits to put fuel injection on, and believe me I am getting tempted! It would be nice to get the car driveable for a while first though.
Thanks in advance for any suggestions.
