Carb Tunning
i did a search on carb tunning, Carburetor tunning and q-jet tunning and nothing helpful came up so im wondering if anyone had a website where i could read up on how to properly tune a q-jet carb that would be great (not rebuild but tune) i know theres the airflow mixture screws at the bottom near the intake but other then that im useless. and well tunning those turning right or left i find doesn't do much... the carb was running lean before with i think #72 jets and now has #77 jets hoping to make a diff. but it still seems to run a lil lean up top when its around 4500-5000rpm's. It was rebuilt bout a year and a half ago. it originally came off the 305 before and now sits up top a 350. so any hints on how to tune it properly would be nice or any suggestions or sites that you know of.

There's a guy on here called Sonix. Search his name and look for a thread he posted in that I started. There'll be a link he gives me to three amazing articles.

well those are the searches i did, unless i missed somethings which said specifically carb tuning, or carburetor tunning or q jet tunning then i am blind but when i did the search it was all something within a thread which was well sorta topic related but not what i was looking for.

Its 'tuning' not 'tunning'
Not being a jerk, just that the Search is spelling-sensitive.

the carb forum isn't all that active, just scroll down. look for anything asking about a q-jet.
Then ask supplementary questions. but be sure to add info like:
Are you using the cc-qjet? Why do you think it's running lean? etc.
