What would be the symptoms of leaky boots...

the boots bewteen the carbs and engine?

Don't know the exact symptoms, but to diagnose it, have the engine run in idle and spray a little brake cleaner on the boots. (Attention! highly flammable!) If you notice a change in rpm, the engine has sucked in the good stuff through the boots.

I was gonna say........ wet feet

Engine will run lean, usually accompanied by excessive heat and flakey rpm's. Slow to idle down. Or idle will hang at a higher rpm.

Glad to see I'm not th eonly one with a bad sense of humor (I thought the exact same thing!)   :lol:

WD-40 is less volatile than brake cleaner and more viscous.  It'll seal up any leak longer than something thin like contact, choke, or brake cleaner.

AFAIK you don't spray the stuff there to seal the boots (as typical problems of leaky boots are intermittent anyway), but to get the stuff sucked inside and burned, thus affecting RPM. But WD-40 should do the same trick, as it also contains quite volatile, highly frlammable components.

I suggest spraying the brake cleaner into a straw and using the straw to drip it onto the sealed area.  Less dangerous and it will still get sucked in if there is a leak.  If you can't get a positive yes or no then just take the carbs off and replace the gaskets.
