Thanks for the input. If I do decide to buy it the first thing I was going to do was pull dizzy and prime the oil system after changing oil and filter, drain the carb, replace the fuel filter and use fresh gas out of a can.
Pull the valve covers and make sure you have oil to rockers while you are priming the oil system
Before you pre lube it (good idea) pull the spark plugs its alot easier to turn it over after you lube it.
Look at the plugs good they will tell you alot, if there is rust on the plugs there is most likely rust on the cylinder wall's.
Good Luck
