1970 911T hesitation at 3k RPM
Any thoughts on what might be the cause of hesitation/'hiccup' at approx 3000 RPM..most noticeable in 4th/5th gears. Its a 2.2L with Weber set-up. Car runs very well otherwise.

My $.02
Just a wild guess... Idle valves in carb's, or the beginning of a couple of dirty spark plugs??

My experience has been that this is often caused by poorly synchronized carb linkages.

I have a 71 T with 2.2 and Zenith carbs. I had a rough idle and popping and backfiring through the carbs. I posted a similar question to yours about my issues and got replies to do a search on the site. I did and found a ton of info about adjusting my Zeniths. I have adjusted my carbs according to info I found on this site, and they are much better! I need to work with them some more to get them completely dailed in, but it runs much better now.
So, long story short, do a search on this site about adjusting your Webers and good luck!
