I accept that it is virtually impossible to diagnose the cause of a knock, tap or squeak without actually hearing it first hand, but I wonder if in this case someone could either confirm or question my suspicions on the origin of a knock that is emanating from my 30BHP engine
My suspicion is that it is a small end knock based on the following:
It is only audible during idle, and even then it comes and goes.
It is a low down knock.
It disappears as soon as the engine revs are increased.
It can’t be heard when the engine is under load.
My feeling is that anything from the big end side of things would be there at all engine revs and would be particularly noticeable when the engine is under load. :?
What thoughts have you?
Thanks
