Hi im trying to find out how old my engine is the serial no is 676b002302.Also how long should it take for the water to come out the pee hole or dose any one no what might be stoppig it coming though thanks.
I find a 676b listed in 78 but the serial numbers start at 401141 and thats the only year that a 676b is listed, if the engine is not overheating the telltale is probably just pluged up try to blow it out
