as far as i can tell there arent any vaccuum issues anymore since i pulled the cali evap (leaks or vapor locking) i havent tried to change the inline filter at the t fitting for the carb because i dont quite unterstand where and what needs to happen for that. nervous about getting over my head, when i asked the mech he looked at me like i had 2 heads, i assume its a stock cvk carb so the jets should be normal, but have heard that the early bonnies were design to slioghtly run lean. would plugging the a snorkel and dialing up the fuel mix screw do the jon without causing detremental damage. or atleasat run her better till the end of the sean when i can oput more time into the carbs/intake myself. and to the pipes is there an easy way to open them up i.e. remove some baffle? i come here to search for info because i have a difficult tim finding iunfo elsewhere. wrong model year info pops up a lot.
