Can low compression cause hard starting?
Low compression doesn’t necessarily cause hard cold-starting problems, its usually the other problems that go along with it that do. Along with low compression comes oil consumption, which usually fouls the spark plugs, even only slightly.
Can bad valve stem seals cause low compression?
