Won't Start need advice, Please read....

Do you have a timing light? If so, pop it on, see where the balancer timing marks line up when lighting... Does the crankcase oil on the dipstick, smell more like fuel,than oil? After that, I would do a compression/leakdown test (s). Tool rental is free, from O'Reallys/ Autobone stores. What do the spark plugs look like?
