i recently received a 1988 50 pro that is idling at 2500-3000 rpm. cleaned and rebuilt carbs all new gaskets. still same symptoms all throats are closed and manual advance is where it should be (all the way back). i am thinking either charge coil or cdi. i do not currently have a manual for this motor so i do not know the peramiters i need to meet when testing the electronic components on this motor. thanks for your help

hook up a timing light to #1 plug wire to see what the timing is set at. -

My C40 TLRX starts at 7 BTDC, but after warming up it drops back to 7 ATDC.
Timing is Con*****ed by CDI with input from temperature switch and wiper on CDI
You need to find a service manual for your motor to have a look at specs to be sureComment
