I heard a great trick last week from aircooled Bruce.
I thought it was so trick that as I was installing Whitecloud's new Jet Doctors and allen-head idle jet holders, I called Pat Downs for a bit of advice and mentioned the trick to him. He thought it was a great idea.
I mentioned this to Bruce who said: "Why don't you put it up on the site?" so here it is.
If you have Webers (I'm not sure if this works on Dellortos) with Jet Doctors and all of a sudden, on a drive, you notice the symptoms of a clogged idle jet (as happened to Robert during the SOC get-together recently...think fire!) like farting (not you, your car), hesitation, back-firing, you get the idea...pull over!
You don't want to continue driving unless you really want to use the rear grill as a hibachi.
Take the tops off your air cleaners and pull out the can of compressed air (you can pick them up at Staples or any office supply place) and blow down into the Jet Doctors which will (usually) dislodge the contamination and move it into the float bowl.
It may still find it's way back but you just might get all the way home before that happens and be able to clean the jets in the convenience of your own garage or carport.
Great trick Bruce!
