Why would you assume it doesn’t have oil or a filter? 30 years of messing with cars, it has oil.
Maybe this is why.
My parents let my ex brother in law jack with it so who knows what all isn’t right. Today I found the carb wasn’t bolted down.
My question is why would you question someone trying to help you?
Firing a motor that has sat for some time is relatively basic.
First thing I would do is drain and replace the oil & filter.
Next check for spark.
Check timing,
After that fuel is the only thing left.
Oh and if it sat a long time there might be something restricting the exhaust.
