C.D. prescription questions

[FL02]

I've been tuning my weber 32/36 and have been seeing the little jet squirt gas in the carb. I've read where you all plug the hole to smooth out the carb. I've found that sometims coming out of corners when I stomp on the gas, it sorta chokes out and nosedives (so to speak). I figured it was probably the extra gas squirting in the carb and was going to plug the hole, and was wondering what everyone's thoughts were on the weber 32/36 C.D prescription, and how it has worked for other FAQers. Also what did you plug it with. I was thinking JB weld, or Epoxy. Thanks

for me, changing jets didn't help...in fact it made things worse.....i couldn't get it to lean out and it had a miss at idle...i did plug the hole too...used jb weld and regret doing that as well...there's still a slight miss at idle that i can't eliminate now

i put my 25 year old jets back in and the car ran like a champ again...my opinion after trying...if it ain't broke, don't fix it

i'm certain many others have had good experiences though and guess it comes down to doing what makes you happy

I believe the hole you want to plug is the WRONG one. It sounds like your contemplating plugging the accelerator pump jet which squirts gas into the primary barrel when you romp on it. You don't want to do that.

The hole to plug is some sort of AIR enrichment orifice which is located in the secondary barrel. On my 32/36 DGV 5A (manual choke) it is a small brass tube that protrudes down into this secondary barrel. It connects to the top part of the carb and I imagine you may plug it at either end.

CD may post his weber schematic with the orifice circled but I found this unhelpful for identifying what to plug. If someone posted a PICTURE of a 32/36 with the appropriate hole noted that would clear things up tremendously.

I've never followed the CD prescription as a 170 main jet in the secondary is going to suck MUCHO fuel whereas I'm looking for improved economy.

.....PLEASE don't confuse the injection from the

accelarator pump vs the secondary enrichment

during high load/secondary throttle opening.

Use a small dab of metal epoxy to plug the single secondary

passage (tiny brass orifice fitted to the bottom of the carb top

matching up with the main body hole)

One mans result of 'rebuilt', , 'adjusted' , 'checked',

is anothers botch-job.

The power delivery should be seamless, and no 'steps'

or hesitations during increasing throttle openings.

The jetting wont do a thing for you without "CORRECT"

compression, valve clearance, cam timing, ignition dwell,

timing, ignition advance, spark plugs, wires, coil,

intake manifold to carb port matching , ................

have fun.

Its lots of fun. At what altitude was that precription made for?

i'm at 2112 feet

....don't drive HIGH

I use CD jetting prescription and I also plugged the correct hole in the secondary as directed. Without doing any other changes, the 32/36 DGV weber with the jetting gets better performance and gas mileage then the stock solex 36/40 PDSI. I live in Sacramento about 50 feet above sea level and the set up kicks ass!!!! Highly recommend it to anyone near sea level.
