Argess... go to the site ... 4secondsflat.com and look in the technical section . There is a short video on setting up a Demon carb ... but the basics apply , and also a great section on reading your plugs and what to do about various problems . I got his tuning guide ( $20 US ) and one "tip" when adjusting your carb is don`t touch the throttle while adjusting it . If it starts to drop off , tap the accelerator primary pump arm and see what the engine does . If it drops rpm more , you are too rich .... turn the screws in . If it speeds up , you are too lean . Repeat process for the secondary .
I also got his bushing kit for my MSD distributor and installed it last night ( rich at idle ) and then bumped my initial timing to 24 degrees (900 rpm ) while keeping the max at 36 degrees and it really cleaned up my idle . Next is to try the next bushing ( 10 degree ) and go to 26 degrees on initial and still a max of 36 degrees .
The potential downside is possible run on if the idle is too high and listen for ping as you start off ... which I haven`t experienced yet . The other is it may be hard to turn the engine over if there is too much timing , but he covers how to handle that also .
I`m an old racer and thought I knew Holley carbs , but he burst my bubble .
His biggest point was to get the ignition correct before attempting to adjust the carb .
