I've ran Briggs engines for years and usually the plugs last that long also, but I have a Briggs engine in a new purchased John Deere LA 135 LE that has fouled the plugs around 75 hours twice in its 150 hour life span.
I know when to replace them because of the sputter, pop, fart, banging and very bad exhaust smell. The only additive I use is about 1/3 the recommended amount / instructions on the container of Marvel Mystery Oil in the gasoline. The gasoline I buy for it is 92 octane and has no indication of containing alcohol on the pump. It definitely does not sip gas. Any ideas to correct the problem or is this standard for our new non polluting engines.
The usual recommendation is a hotter plug and a different brand but I would think John Deere would know what plug to use in their engines. Any other ideas ?
