New Member MontanaMan just bought 1948 Cub

I will keep you guys up to date as I work my way through the tractor. Would you use the standard Auto light sparkplugs?

[Don McCombs]

I have had good success with Champion D-21s. Autolite and NGK are also good, in a similar heat range.

Thanks guys, I will follow your advice. How do you free up stuck valves? Mystery Oil?

MMO is a good lubricant to add to the fuel for sticky valve problems. If you have any stuck valves, a compression test will be a good way to check. If you find that any are stuck open, try lubricating the valve through the spark plug hole and lightly tapping the valve to see if it will go back down. Might have to repeat several times. Remove the valve adjustment cover behind the carb and lube the area liberally. Also from this area it might be possible to rotate a stuck valve by using needle nose vice grip pliars and help free any that might be stuck. On the other hand, you might get lucky and not have any stuck valves. Good Luck as you explore your cub. Stan

TM sells the oem steel needle and cage separately from the kit, but the cost is $54. As Bill mentioned, the viton either works, sticks, or leaks. Better to use your original, they really don't wear out.

Hi,
Below is a post I made telling how to prime the engine oil pump. It is about half way down the page.

Great info! Thanks for all of the help.

Get the whole tractor with the stuck engine from your mechanic. These tractors do not like being alone.

Hey all, just found out that the parts Tractor I brought home with my Cub is a 1948 Super A. Are any parts interchangeable off this tractor with my 1948 Cub? Thanks

[Don McCombs]

Very few.
