[Spridgets] Won't Idle Down

Hi Bert,

Have you synchronized the carbs?  If there are no vacuum leaks it sounds like one throttle plate is open.  What needles are you running?  A leaky side plate won't make any difference to the idle speed.

Because of back issues, I was never able to properly sort out the trouble. The screws are out to the point of being loose. Before I installed the new carbs I went over the whole car, timing, ignition, plugs, valve adjustment.

My friend is not yet a list member, and I still feel some responsibility to help him getting the Midge running properly.He says he checked for vacuum leaks in the usual manner, to no avail. There is a slight oil leak from one of the tappet side covers that I suppose could draw air into the breather, maybe unlikely.
