Opelnut1 ... We should try to get a rocky mountain Opel car gathering here in the west.... R U up for it? I plan on bringing the GT to the Ranch in Loveland Colorado in September for the GoodGuys show however they will be mostly all American made Muscle cars... They might not get the GT attraction and that is OK.... Gotta love that car enthusiast crowd....
....Hint, check with a magnet. Answer: steel.
Can also powder coat hood latch and brackets instead of chrome.
OPGTS has the pivot bushings for $16.00 pair, Part 2042.

Finally got around to putting in the F-66s and I still have a stumble occasionally from Idle. What do you think I should try next?

It could be that timing is a tad off. Try advancing or retarding the distributor a little each way and go for test drives. Beware that too far advanced makes the stumble go away, but then makes it hard to start.
Consider the probable fix: Trimming a loop or two off of the acceleration/power valve spring in the top of the carb's lid. It's been said that EVERY Opeler could benefit from weakening that spring. Webers are preset to have that valve open at a vacuum range that is very close to what a typical Opel engine runs at. This causes extra gas to be injected at idle, which you DON'T want.

Thanks Gordo... I'll try timing then spring if need be. I ordered an extra spring as a backup in case I fark it up.

Ugh....this is how rumors get started.
You ONLY need this modification if you have a significant performance cam. Otherwise, put the thought out of your mind.

take a side cutters and keep cutting a coil off until you reach desired result. in my case it was way more full coils then i thought it would be. what cam you have though?
use a mity vac

Cut the first full 360 degree loop off of the round end with the white washer. The first loop is flat and has no "rise" or lift to it, so this will have the least effect on the spring strength. Reassemble and test to see if the bog or stumble seems to have diminished. It would seem logical to me that if you notice an improvement, however slight, that you are on the right track and the power/acceleration valve may be the cause of your issue.
Then try cutting off 1/2 of a loop from the same end of the spring and repeat the above. If you continue to see improvement in regards to bog/stumble when going off idle, then it's decision time: Try for more improvement by snipping more half loops or let it be for a while, drive, and see how it goes. The latter would, of course, be the prudent approach.
I understand Bob's concerns and he's certainly a much more reliable authority than I am. He's also VERY concerned about giving people inaccurate advice. I'm not, 'cuz I'm a whackadoodle. :veryhappy
I just have my one experience with the Red Baron to go on. I had a Weber 38 with a slightly more aggressive than a Combo cam on a beat 2.0 with bad compression that I had to throw gas at to run reliably. I had to cut the flat loop, plus 2 whole additional loops, but I ended up with zero bog and could punch the pedal from it's 750rpm idle and spin tires in a heartbeat on a car with a squishy, gooey, automatic(Ha! Dan!). No reving required. My previous GT/Weber experience was with a new 2.0, a Combo, and a Weber 32/36. I never jetted it or did any alterations to it and I drove it for 200K miles and suffered the bog the whole time. It's now so ingrained in me to flutter the gas pedal when I go off idle, that I can't seem to break the habit when driving a GT. I'll probably end up doing the flutter when I get the side draft on the 2.4 working.
I'm sure you have a fresher engine, so I'm sure you'll need less "spring tuning" than I did.

Not sure about the cam.... Keith would have to answer that one. Here we go... Remember it's a backup.

Send me a PM with your real email address and I'll send you all of the blitz graphics I have. One is a bitmap that you can scale up or down to any size you want, print it, then cut it out as a stencil.
