It no longer missed.
Are you talking about Dextron III Transmission fluid? I put an additive in there just for loosening up stuck valves and it seemed to help... but I'm thinking about pulling off the valve cover and spraying carb cleaner. I was told by a mechanic around here that might help... there seems to be a lot of ways to do this that has worked for people but i'm not very confident haha seeing as how I haven't worked on a lot of vehicles.. i'm just afraid to wreck it and then be out of luck. Would a bent push rod cause that much noise too? It just knocks like ya wouldn't believe and i know that its not like a crankshaft knock cause the engine just sounds tight. This thing has been sitting for like 7 years then they started it up with bad gas. I didn't know that they had run it on bad gasoline for a while until now.
