Hi all, again,
Yes I've discovered a new problem with my Suffolk 75cc engine, When I start it up it knocks very loudly whilst running, I've never had this problem with any of my engines so I havent a clue as to what to do. I removed the head and when I did so, some dusty looking smoke came out, this could just be the oil smoke, I inspected the bore and all around and other than the usual oil all looks fine. It knocks a bit when I turn the flywheel by hand, but I think I remember this before but I am not sure.
Ed Redfern if you are reading this ( or listening), I have cleaned the points and polished them and I have a great spark, I can even get a good one from spinning it by hand without the pull start!
Just after some advice.
