We had temps of 98 and heat index of 108. The motor did a few funny things. Hit the key to start it and it would fire then die. Hit the key again and idle normal. Seemed a little slugggish. My partner also has a PRO XS and he noticed it also. If I give it a little throttle just to get it to about 1000 RPM seemed smooth. Could I have gotten some bad gas? I run Quickcleen and Marine Stabil. It ran fine on the top end with no issues. Once started it never died and I had no alarms of any sort. Could it be time for some plugs? Just reached about 125 hours. It has always had a slight little miss but it seemed to really be worse over the weekend.

Thanks
