Yeah, like smallengineguy says, drain the tank even if there is no water in the fuel, after sitting for a couple years, it will be funky and adding new gas to it will make it less funky but funky nonetheless. He is right, if its watery, it will sit on the bottom and suck right back into the carb. When I up ended my safari tank I was astounded at the stuff that came out; grit and crud and 2 gas can funnels! As for the oil lines, take em off and blow them out and also blow out the nipples going into the engine. I cooked a 377 once because of crud in the oil line on one side. With good spark and good gas, it should be good to go.
