Rough idle, low power, high MPG, not flexible acceleration, too long of a cranking  time with a hot engine.......you probably have a damaged fuel distributor diaphragm (even the smallest one) or an internal leak in the fuel  distributor, or both. This is probably because of modern fuel additives & the introduction of ethanol into fuel.

New patented  technology (laser cutting under the pressure of liquefied inert gas) allows us to maintain not only absolute precision in manufacturing the stainless steel diaphragm, but also handling the cutting corners in a way that the edges of the diaphragm and especially the manufactured WURH (worm up regulalator hole) are ideally precise without compromising the geometry of the diaphragm.
