I need to make an amendment to what I said earlier about the amount of turns out the idle adjust screw was...I was only counting 1/2 turns, so in actuality it was about 7-7/12 turns out. Now, I put in the 65f9's and got it down to about 4 1/2 turns...so I'm going to be ordering 70F9 and 75F9 just in case the 70's don't work.
Since we're on that topic, where does everyone get their stuff from? There's only one place I know of in town, and they are geared toward VW's, and the 65F9 was the largest idle jet they had. Websites I have are:
www.piercemanifolds.com
www.webercarbsdirect.com
Also, I was thinking about getting one of those synchrometers to get everything tuned precisely. Any suggestions/comments on those??

keep a log book to keep track of which bit you are using. how do i do it? i keep on drilling until the car wont move anymore and then use a jet smaller. I do the same with my main jets. to be honest, I dont even know the size anymore but again, thats my driving habit. thats cheaper than spending bucko bucks on jets.

Well I was just in the garage doing the drilling to the jets, and tuning from the engine bay. After adjusting the idle jet screws a little, I hit the throttle from the engine bay to check it out...and the throttle cable got stuck behind the throttle stop screw for about 5 seconds pegged. 95% sure I just blew my engine.
SO A NEW QUESTION! Will this carb setup handle a half bridge 13b?!?!

the answer is yes, a 48 should be fine, intake is a little bit long, but the carb is big enough

Well I just went back out there, sprayed some carb cleaner down it and it finally started up. Maybe it got flooded, I dunno. It's definitely not as easy to start now, but it starts, and runs, and doesn't sound terrible.
