去年年底斑竹的建议用spark plug pressure gauge测压力变化,试否?
斑竹当时的原文:use a spark plug pressure guage, to screw in each spark plug hole, hand rotate the engine to see if the pressure changes. If any one of those cylinders does not show pressure change, the valves for that cylinder need work.
还有buddy1234567us的,建议:如果不换缸套(我见的多数人不换缸套和活塞), 一定要用3个爪的电沙轮磨缸壁顶部. 旧车缸壁顶部的直径都会明显变小, 增加阻力. 另外, 活塞RING的间隙挺难掌握. 不要磨短了. 别的没什么难的.
