Flathead V8 spark plug colour variation

[Phil Waterman]

Hi Richard

How old is the gas, modern gas (at least the stuff in the US ) goes bad so quickly that I've given up trying to do any engine tuning without having system filled with fresh gas. Also find that it take an hour or so drive to clean out the engine.

Of course my CMPs have two less cylinders to start with.

Cheers Phil

That's interesting Richard .... I will try not to let her idle long then when I get her back to the shed after the road run .... I'll switch her off as soon as I roll in.

And Philip the gas/petrol is from early start of the year ... so probably on the turn ! Good point !

Many thanks,

Mark

Phil, Lucas make a 'fuel stabiliser' (or stabiliZer in your version of English) that I can recommend. Prevents the fuel going sour, even over an extended period. Great for ski boats during winter storage etc.
