Got an '86 GL with the electronically controlled carb...the secondary barrel does not work when needed (under load) and does not act like it's plugged...is there a solenoid or switch that is not working on this carb?

hi

maby the vacum pipe is disconnect or maby it's a very old pipe and let some air to go out......change this pipe that connecting to the diafragma.

this is a DCP306-24 carb...it has no hose connected to the vacuum actuator, it is a sealed unit bolted to the carb...vacuum is created by a spring/ball system to the diaphragm, both which are in remarkable condition...nope, vacuum lines are not the problem here.

Check the diaphragm to see if it's torn or obstucted.
