Guys - Got a nose mount Mallory dual point on the Track Roadster; after much carb T-shooting, I'm convinced there's a prob up there. dizzy is brand-new - as is the internally ballasted 6V coil. Here's the deal - motor runs okay from idle to *about* 2500 RPM, then the ignition starts to break up - like spark blowout. I've run a hand tach on the belt...she's idling at 600 RPM now (turned the idle down) and the plugs are fresh. I tried to wind it up past 2500...it's done (as in won't wind any further) at 3500. Have tried several timing settings all the way back to TDC - same result. Looked for my Mallory paperwork, and can't find it. What gap are the points supposed to be set at - and how do you limit the total advance? Unit is a full centrifugal (mechanical) advance dizzy. As always, advice is appreciated. I'm stuck waiting for the driveline bearings, so I might as well resolve this issue in the meantime... Thanks! Chuck.
