Girlfriend's Rig, she let a few friends work on it. One is a back woods mechanic fix all type and he went down and put a higher octane racing fuel in the rig saying it would help "Clean Her Out". Also that these engines were designed for leaded gas and the leaded racing fuel would be good...(It has sat for a year or more)
How it runs right now, I question all of this. I always thought racing fuel while it can contain lead for a higher octane rating and more "power" is designed for engines that need it. Right now the truck is idling horribly, decent amount of black exhaust on idle and smells awful to boot. Used to turn over with just the choke out and a turn of the key and now takes pedal pumps and many feathering attempts when it does start...
Should we just be running normal octane gas or does her friend have a point about the racing fuel. Would hate to see this do any damage to the engine. Which was running really good for it's age when we parked it for the winter.
Thanks,
