I gutted a duster cap that seals underneath it. Should seal better. No more fuel running down the 1/4. Hopefully. Found my fuel vent completely plugged by some kind of mud toting insect. Might have been some of my drive-ability issues. I did a bunch of dumb stuff to that car long before the internet. Ruined the heads by porting wrong I now believe. Had 202's put in J heads. 273 rockers shimmed up cause the pushrods are too long. Small exhaust manifolds really choking it. It never did run like I thought it would.
