I always assumed that sound on my /6 was from the sloppy leaky throttle shaft bushings. Yours OK? I never did get mine resolved before tearing the car apart for resto.

Those 46's were gone through by Bieker, they are better than they were new. Have needle bearings instead of bushings.

Just my opinion, but I would jet down the 46's you have, toss some 36 vents in there and tune them properly.

I bolted the carbs on, went for a ride and thought, Damn, that fixed a whole mess of shit.

Compression when I checked it was 155-160 across the board. Unlikely your leaking anywhere. I also replaced I think 8-9 exhaust studs, so everything under that should be tight as well. But things can happen and change.

Those 46's are $$$$, don't let them go that easy. You can get them to work just fine on a 2.7.

I did only drive the car 2-3 times after putting those carbs on. So I never tuned or sync'd them better than my ear. But the car would would give a healthy CHIRP into second gear every time full on. It should still be nothing less than an absolute rocket. If it isn't a rocket, something isn't the same. Messix can atest to that. (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif)

Alan,

46 IDA Webers are a bit big for a 2.7 S CIS engine. I have been running 40 IDA Webers on the same eingine with 32mm venturies as per Richard's (PMO) recommendations and they run great.

Would you like to trade?

Eddie

Eddie, what happened to that new motor you got? Is it in yet? (IMG:http://www.914world.com/bbs2/html/emoticons/jerkit.gif)
