9.9 4 stroke-New carb.. Idle wont stabilize

[rorkin]

Just put a new carb,.. new inline fuel filter, new plugs .. new gas .
Idle speed will not settle down. runs for a few seconds at speed then climbs up a couple hundred rpm (a guess) then goes back down.. cycles Up and down..
Anyone have an idea where to go from here ??

yep you have a vacuum leak somewhere are all the gaskets in right

Put in new ones seems tight .. there is really only one way to put in if you check out and match the holes in carb and spacer
