I have had problems setting the float and getting spark on the bottom cylinder of this thing. I seem to have the float set and have finally succeeded in getting spark on the bottom cylinder. Here's how--I disconnected a single wire that goes from the points/coil/condenser connection to a device on the front of the motor up and to the right of the carb that has one vaccuum line going to it. I have from the most reliable source that it helps the motor rev down smoother by killing power to the spark plug on one cylinder. Since the wire attached to this device goes to the bottom coil/points connection, I assume this is the one it kills. Now, I've checked the connection on the device with a meter to see if it is grounded and it is not. I believe under enough vaccuum it will complete the circuit and ground the wire and short the ignition to the bottom cylinder. My question is, why is it shorting the bottom cylinder's coil if the connection on the device is not grounded. I couldn't find any bad insulation on the wire connecting the two.
Question 2-- I can't seem to get the motor to idle down smooth. I have cleaned the carb. My gasket on the high speed nozzle between the 2 carb halves isn't too sporty. When I turn the throttle down a little it will idle down for a few seconds and then die with a hard cough. If I richen it up with the slow speed knob it will not idle down without dying quicker. It will fast idle with the high speed valve totally closed.
ALso, I feel very little vaccuum on the hose going from the intake manifold to the over-revving control device. Should I feel quite a bit?
Sorry for all the questions but this thing is really eating me up.
