Do solid engine mounts lead to flooding the float bowls?

I know what PMO recommends regarding solid mounts for engines.
Hey Paul,

1) Yes,......the frequencies of those vibrations cause mixture variations in the engine. I've never been able to actually observe what happens inside the float chambers so I cannot say precisely what happens, however the use of a flexible engine mount (rubber or urethane) eliminates the problem.

2) Soft-mounts on IDA's do not work due to vibrations. The DCOE ones work in those applications since the carbs were designed for them.

Hope this helps,
