I have a 70's-80's belarus 800, this is an all mechanical engine, i have a cylinder not firing, it is getting fuel, and i have switched the injectors around so the mis-firing cylinders injector is in a different cylinder, and the same cylinder is still mis-firing.. no change.. so its obviously not a bad injector, so assuming the cylinder is getting fuel (which is a pretty safe assumption), what else could be the problem? I changed the head gasket last year, did it myself, and ran like a top for a while. I have took the valve cover off and the bolts for the head off. The oil in the valve covers seems very milky and makes me think the head is bad again? not sure here.. cracked block? bad ring on that cylinder? bad head gasket again, perhaps due to improper installation or warped head? any advice/input would be greatly appreciated!
