That what I thought at first changed out last week didn't help talked with mechanictoday . trip to the shop will find out results in about a week.its one those 2/4 carbs idles on 2 run full throttle on 4 said it probaby something stopped up !
Yes sir! sea foam was first then new fuel filter . It still starts fine (lol) after I hooked the rope back up to the kill switch
just has a miss went ahead took it to mechanic said carbs could use some cleaning . And if I tear into it it wouldn't ever run again.
Sounds like an overly rich mixture of fuel. A needle valve in one of the carbs not working correctly will cause the symptoms. You can trim the motor up to a shallow water drive position and prime the bulb while viewing the carbs. If it's a needle, one of the carbs will start bleeding fuel.
I'd rather be fishing.
Update. Wire off of the stater ? And Coil pack not firing 260 bucks later running great
