no they aint, is that a problem? they are angled ... but I saw the problem now! it was so clear... after I fitted the carb with a new gasket and tightened it, I saw the carb was skew on the backplate... the one bolt I could turn it so tight it pulled it away from engine so not flush anymore as I could see also light pass through... I added some gasket glue to it, seems there's no light I can see pass through... else I would need to purchase a new backplate...
