Maybe someone can help me with a mysterious problem I'm having with my 225. The engine has an intermittent loss of power @ freeway speed (can't pull in overdrive). When I come off the freeway ramp and idle at a light, the engine losses rpm and dies. Here is the wierd part. The engine then will not start but issues a blue cloud of bad spelling smoke out of both side pipes. After a few minutes of sitting, the engine will crank w/o issuing the mysterious blue cloud of smoke, then starts with a thick black cloud as if it had been flooded out. I've replaced points, plugs, plug wires, distributor cap and fuel filter. I've had a carberator man open up the G2. He says everything looks ok. Has anyone had a similar experience?
