Einstein told me it would work! LOL. Actually this technique is nothing new since its been done in the automotive field for more years than I would like to remember(just reminds me of me age). The old Quadrajet carbs with vacum operated secondaries had an adjustable spring to regulate how fast the butterfly would open and Holley vacum operated carbs had different tension spings you could buy to install in the diaphram to tune the secondary. Its really old school technology.
Must be the younger generation is lost if its not fuel injected.Ha ha ha!
I cut my carb spring about 6 coils shorter. Just that did not seem to make much of a difference, at least not for the worse, but I can't tell if it's for the better. It didn't hurt it anyways. Where are the 2 holes to drill out to the next size bigger? I don't know where they are. Thanks
if you remove your slide and look at the bottom of the slide you will see the holes on either side of the needle. I did this mod and my front end comes up much more. its a lot more like my 400ex than my stock predator. I like bringing the front end up as I come over the crest of hills so It was a good mod for me.
