I have searched the web site and have not found an answer to this question which I suspect has been asked before. So, here goes.
Should I use regular 87 octane gasoline or a higher octane gas (89 or 92) in my cub? What is everyone else using?
Also, a little good news ... after months of restoration work on my 1949 Cub, I install the battery, pulled the starter switch and it fired right up! Needless to say, with so little time before the 4th of July Parade in Crest, California, I did not a lot of time to troubleshoot the tractor had there been a problem. I am definitely smiling tonight.

Hi Tom
I don't have much seat time on my cub, even though I have had it and been reading the board for 3 years. Most everyone uses the 87 as JB said above. Some folks have also asked about if they needed to use a lead additive, and I also believe most do not use any, just the 87. If someone has had a valve stuck and just got it free, they may use a very small amount of Marvel mystery oil in fuel. I don't know how much or for how long though, maybe some of the pro's on here will chime in on that. I do use fuel sabilizer (STA-BIL) in my cub, as well as all my other equipment, keeps fuel fresh for quite a while and things don't get all gummed up. The Stabil brand can be used on 2 or 4 cycle engines. The stabilizer producd by Gumout says it can be used on 2 or 4 cycle engines, Kerosene engines, or Diesel engines. I have had good luck, sometimes my equipment just sits with no use, but with the STA-BIL they start up 1st or 2nd try. Paul K. in N.H.

I just use regular (87) from the pump unless I am going to use it hard like 2 to 3 hours garden plowing where you are right on the end of the handle then I add a lead additive or just about 1 tablespoon of 30w
non det. per gal of gas.
The valves were made to use leaded fuel.
To putt putt around unleaded is fine but to work it hard it burns to hot
& the lead or oil retards the flash point so it burns cooler.
Found this out the hard way burned 2 valves.

If it's been broken I did it.
If its not broken wait till I touch it.
