Fouled plug

[john2189]

I have one cylinder that fouls the plug. Could i just use a hotter plug in that one cylinder? ir should it be a colder plug?
I use it full throttle to mow grass with a woods 59.

fouled with what ? oil ? Gas ?

Oil, I know it would be a bandaid, but can’t have it down right now.

I suspect they're still available, but there used to be a device called an anti-fouler. It's got male spark plug threads on one end and female on the other. You screw the spark plug into it and It essentially moves the plug farther out of the combustion chamber to help reduce fouling by tired rings. Might get you through your mowing season until you can affect a better repair.

I had the same exact problem on my cub and dealt with it the same way you're suggesting. I found that the NGK AB6 (stock #2910) didn't foul.

Thanks, I’ll try them.

Is an anti-fouler going to expand the combustion chamber and lower compression

If it oil foil then get it fixed. No plug i
Going stand up very long. .

Hi,
They say on here if the engine is smoking, or has low compression, to put Seafoam oil additive in the engine oil. It would probably keep a spark plug from fouling, if the oil stops going by the rings.
They sell it at auto parts stores.
Piston rings commonly get stuck, and then the engine will smoke, or have low compression, or foul the spark plugs.
It could help the compression, if the rings are stuck, and the Seafoam loosens them.

Make the engine work doing something when using the additive, so it warms up.
I have read on here of people having good results after using the oil additive.
The seafoam probably needs to stay in the engine for some hours of use, read the instructions on the package.
The 1949 Cub owner's manual says to change the oil every 120 hours of use.
If the piston rings are wornout, the seafoam won't help much.

I have used Rislone, and had good results with that brand, it is an oil additive also.
I haven't used the Seafoam, but have read people's posts about it on here.

Easier said than done! The poster has already said he can't have it down right now and we don't know the complete story. JMHO Stan

I do want to rebuild it, just can’t do it right now. Just want to finish the mowing season and chop up leaves when they fall.

Try a different oil, some have a higher ash content.
