Should all three carbs have the same amount of suction from them? If you put your hand over the top carb it practically stalls the engine, and sucks your hand into it, the second is less noticeable and the bottom is least noticeable. Is this normal? The motor doesn't seem to have all the power it used to have.<br /><br />The compression checks out fine all between 130 and 135.<br /><br />thanks
