96 150 johnson ocean runner idling to fast

[D MC]

I've had my motor for 16 years and it has always @ "cold "start ran 1100 rpms for about 1 1/2 minutes then drop back to 800 rpms. After that warm up start any time I crank up it would run at 1100 rpms for only about 5 seconds then drop back to normal idle of 800 rpms.First few times I cranked up yesterday after installing a new vro pump it did the normal rpms as always, then it started not dropping rpms. Thanx for any input. D MC

See page 64 in the CDI troubleshooting guide your engine is staying in Quick-Start mode. The link to the guide is in my sig.

hidef '''''FANTASTIC INFO""" I was impressed at how the info was in layman terms that you could follow to check out the quick start system. I found a bad spot in the wiring harness on the temp sending unit.White with a black stripe wire on the port bank. Butt connected it back together and it runs perfect agan. THANX A MILLION. D MC
