I read this last posting and it looks as if there are no limits...

No limits to what, Hubewrt? Please be more specific.

GScott stated he felt exhaust or some kind of gases leaking beneath the spark plug area....how does anyone come to the conclusion it is the intake air boot ?

 

I don't know, but it seems Docc was right on the money if you read GScott's last post.

 

 

mea culpa ! I should read all posts before blabbing....

Most likely explanation is the loose intake boot. You can find it by inspection or spraying a solvent, like carb cleaner, around the joints and surfaces monitoring for a change in idle speed.

Carb cleaner eats rubber parts right quick :homer:

 

So, what would you use? (I actually use electronics cleaner, since brake parts cleaner is probably even worse than carb cleaner.)

 

WD40?

 

I've used WD40 to good effect in this role... :drink:

WD40 will work [it's essentially kerosene, so it tends to temporarily seal the leak and add some heavy fuel to a lean condition: idle goes up.]

 

Starter fluid [aerosol ether; again, adding fuel to a lean condition, idle goes up. It will evaporate, so no clean up needed after testing.]

 

Propane [from an unlit brazing torch; again, adding fuel, idle up. Like ether, no clean up needed after, but just remember to turn the torch off after use, so you don't get a garage explosion 1/2 hour after closing up the shed! :luigi::rolleyes: ]
