Weber Cure - It Worked!

[cegerer]

Thanks to 'porsche74', I've cured my Webers that were running rough at low steady speeds.

RE: http://www.pelicanparts.com/cgi-bin/vb/showthread.php?threadid=67154&highlight=rough+running

Interestingly, I found a significant amount of small paint chips on the base of my air filters (see photo below). I suspect these red paint chips are from taking the watershields on and off and the mount holes rubbing on the threads of the hold-down studs. Is this what clogged my idle passages? I dunno, but maybe.

The bottom line is this method of using compressed air to blow out the passages is very easy to do. My car runs even 'more perfectly' than before! What is frustrating is that I've got a couple of Weber books and information from various Weber websites, and NOBODY mentions this simple cleaning method?! Thank God for the Pelican BBS.

Now it's on to improving my air & fuel filtration.

Curt? Man, this board is great! Glad the tip worked for you. BTW, is your car still a Targa?

[dhaines]

I had the same problem from paint coming off the inside of the filter. The car was running real bad if you held one speed. Cleaned it out real good, repainted and no more problem. Glad you got things figured out

I came across some interesting information the other night in the Carrera RS book. They were talking about the development of the ducktail spoiler. One of the side benefits they noticed was a significant reduction in dirt in the motor compartment. Seems that the turbulent air at the rear of the car stirs up all sorts of road dirt and it gets sucked into the motor. With the ducktail, the turbulence is much less and the air is clean!

"BTW, is your car still a Targa? "

Yeah .... and why, preytel, do you ask???? -- Curt

Curt:

Glad I could help. As I do this for a living, I've seen my fair share of Weber's over the past 27 years and I've gone through this many times on other peoples' cars.

As long as the aircleaners fit well and the ends are greased to prevent leaking, you'll be OK. For really good fuel filtration on carbureted 911's you cannot go wrong with a Racor # 110 Fuel Filter. These also trap any water in the fuel BEFORE it gets into the float bowls which will BTW, cause the very same symptoms you've been having.

Enjoy,

[cegerer]

Thanks again for the tips. The filter ends are not well sealed and I plan to take care of that today, as well as find a source for the Racor filters.

I've got another Targa quote in the works. Something along the lines of "Targa: the only road-going Porsche to come standard with a race-ready rollbar." That oughta give the Targa-haters something to ponder. -- Curt

[EWPurdy]

Anybody know the actual Racor part number and a good source for those Racor #110 filters?

[cegerer]

It looks like you can order directly from Racor. It is Part Nr. 110A and the list price is $82.95.

www.parker.com

Warren had mentioned another good - less expensive - filter in a previous thread. It's a Fram in-line G3802A for a 1992 Lincoln Towncar for christ's sake! Apparently, this thing has a 3 1/8 inch outside diameter - plenty of filter area for sure!! About $10. I'm going to give that a try before ordering a Racor setup. -- Curt

[EWPurdy]

Thanks as always for the help. I'll check them both out prior to starting my PMO conversion in a few weeks.

More funnin' from me.... Being a(nother) coupe lover, I noticed something as I reread the copy of the R&T article that Warren posted. Seems both the S and the E used the E's hydropneumatic suspension. So...

"a rather strange combination considering that the new suspension is designed for comfort more than ultimate handling"

Bummer - it wasn't a fair fight . And we'll never know the true outcome.

[cegerer]

"Seems both the S and the E used the E's hydropneumatic suspension."

Yeah, well, the T Targa only had 3 working brakes and Donohue STILL found it superior to the E & S Coupes! -- Curt

[CamB]

But, but, but.. the coupe is better. I say so. Surely I know more than Donohue. Vast racing talent and experience can only count for so much. And I have driven a Targa once
