just had a thought......
should i be running a lead additive for the CJ2a ? i dont know when they stopped using lead....i dont know if the previous owners put in hardened valve seats.....i doubt it, but you never know.will lead hurt an engine if it does have the seats? it smokes pretty bad.....so it will get rebuilt eventually....but i'll prolly tool around with it before then and i'd hate to damage it more....
Can you even get Leaded fuel?
On an old smoking motor, I don't think I would worry about it.
I've seen a lot of damage to Alum motors (VW's, etc) from the unleaded fuel back in the 1970's ..... don't recall much in low compression motors like your 4 banger?
