Help
I have a 1970T 2.2 car run good, I have a studder at high RPMs I thought it was the carbs, I had another person look at it who use to work at porsche dealer, we can not get the 6th bank on carb to respond on gas or air adjustment, I have done a compression test on all cyl. and all seem to be around 110-115 the 6th bank was a little lower 105-110, need to know if the valve is bad before I take apart could it be something else if I spray gas down 6th carb it does not change Idle??? I do have spark on 6th plug, the car Idles great so I dont know if it had a bad cyle. would it still Idle good, almost like Im running on 5 cyle. Hope some one can help.
Thanks for any help |

Youu have to have a leak down test done to evaluate and determin the problem, be it valve or ring related, if it is valve related you can isolate wether it is intake or exhaust as well.

You may have already checked this, you say you have spark at the #6 plug, is this at the spark plug or the connector? You might try just replacing the plug some times they just go bad. Also lightly place your hand over the intake on top of the carb see if it has strong vacuum.

I did replace spark plug, I did also put my hand over the carb, there is little vacuum unless I give it gas.
