I have a 4 gauge sync kit and I'm going to sync the carbs today. I will let you know the results. Thanks for you help. If your floats aren't sealing well and the bowls are overfilling that could cause the same problem – you'll get some extra gas into the cylinder. If you've got the sync gauges I would just do a sync and see where it ...

circuit from the GM is spliced into an existing circuit from the BC to the DME. A High signal from the GM (or BC) causes the DME to cancel the fuel and spark functions to the engine resulting in a no-start condition. The vehicle must be unlocked with the key or the code function of the BC cancelled for the DME to allow engine operation.

Jul 16, 2007· For the Continental engines with the transfer in the main bearing, the cylinder-side gauge should be no lower than 18 psi. If the cylinder-side gauge falls out of these specs (on the low side), then the transfer system is bad and the engine must be disassembled. If this is not the problem, the governor should be sent off for a thorough bench check.
