    "My question is, "can a leaky primer solinoid affect idle speed and smoothness ?"
    If I understand how this little gizmo works--enriches the mixture when the key is pushed in, or the override handle is turned up, and the fuel pump pushes fuel into the intake.
    I have had a concerns about my 200 looper not idling as smoothly as I thought it should when throttling back to idle speed, which I posted about awhile back. The response was the carbs were cycling back down through the high and mid jets.
    I recently bought the parts and rebuilt my solinoid. The only thing I saw in the old parts that looked bad was the o ring on the end of the override handle, it had a flat side where it contacted the bore all the way around it, and had a hard piece of trash bonded on one area.
    I have only ran the engine once since the repair. and it seemed to idle better, slower some I think and smoother when throttling down.
    Any thoughts by the more knowledgeble if the o ring could allow fuel to push through the solinoid
    into the engine and cause idle problems or am I wrong?? Thanks!"

    "Thanks for the comments.
    To answer your question concerning a "full tune up," I have to say no, and do not fully comprehend what is meant. I have changed plugs, wires, checked all the coils with an ohmmeter, cleaned all the bullet connectors. I have run sea foam several times, but have not decarbed as described in the manual.
    Have not checked the oiling system (VRO), or had a professional mechanic do it. Basiscally what is that consist of? Thanks"
