I am 100% that when we started it up ok , like the idle was fine.. not like it was struggling or anything it was just as a healthy engine would do, but we didn't let it warm up.. I know I switched it off to check some other things then mates started up and jus revved it.
However my main question is, if there does happen to be gunk, should I do an oil flush on it? because I was cautioned it would lead to doing the cam and certain other seals as the gunk dislodged.
I can't imagine that this would be too big an issue that it can't be fixed or something?
