I have a 97 90 hp Johnson having some problems. 1st is stalling at idle almost anytime I try to idle it stalls from forward to reverse or any idle time. 2nd wot is only hitting 4600rpm not shore is related. 3rd is i feel im using more gas then i did last year alot more. I replace primer ( was sticking on) pulled thermostats there stuck open ( didn't replace them yet but will this weekend). A marine mechanic told me if stuck open will cause rich condition. He also looked at the carbs and said there ok. Replaced plugs, wires, coils, power pack , and stator no help. Also if I pump my primer bulb it doesn't get real hard feels like its losing pressure somewere. Replaced that too. Any help would be great also the carbs don't have any adjustments is that right?
Thanks
