Set new engine up help?

Great idea SNake hit the right on the money, Best way to do it is to use a vacum gauge. and adjust your idle and mixture screws .. you want a steady vacum most stock engines are about 15 inchs... Adjust your screws closed ...open one and half turns and continue to open untill you reach max vacum on the gauge.. your vacum will increase then when decrease... when this happens begain to close you mixture screws ,,, you want max vacum at idle and drop off to zero inches at wide open throttle... vacum gauge tells you tons of stuff when using it... low vacum may indicate a vacum leak... low compression... a irratic vacum needle indicates valve issues... Great way of check that the engine was assembled good and machined good... Good luck..
