i investagated further today and found out that the inlet manifold was craked and broken on the inside bolt hols, when i undone the manifold to have a look the bits just fell off, is this a comman problem? the timing seems to be right, if i set the timing to 0 it doesn't seem to run very good but if i advance it past 10 degrees it run a little better bu stil wont idle that well. i think ther is somthing wrong with the engine it self, theres some strange noises from the engine somwhere, that only started today when i was working on it! just my luck!
