Sluggish Predator 90 warm up
I've got a '06 Predator 90 that has had the first pre-mixed tank run through and is now on second tank of straight 90 octane. Even though it's stored inside, the warm up is very sluggish. It requires a choke to start and then slowly let off choke while maintaining throttle. After 30 seconds of medium reving and then put in gear, it is very sluggish and sometimes stalls out. Once you can get it moving with choke off and get a minute or so on it, it's fine. Warm up should not be that bad in those conditions. Any ideas? It's certaintly not a rotax 2-stroke ;-)

A minute or two warm up time does not sound bad on a carb engine.
Todays fuel injected/computer controlled engines have us spoiled. I remember many a days growing up sputtering along in cars/trucks of old waiting several blocks/minutes for it to warm up.
Higher octane fuels can also lead to hard start conditions in cold weather. Remember higher octane just means the fuels ability to resist burning, which also means in a cold low compression engine it can lead to a hard start condition.
