Well, first of all you would have to explain why 1700 is fine and Idle up is 1500 ? idle up should have a HIGHER RPM setting.

second, listen to your engine and check its power \ temperture.
if the engine sounds rough, its lean - richen it up a bit. a vibrating engine could be either too rich or too lean. if it puts a ton of smoke and not a lot of power - its too rich. you will have to find the "sweet spot" somewhere in the middle.

good luck !
