Reading spark plugs and re-jetting carburetors is tough enough—and it’s even tougher at the track where you probably don’t have a workbench nearby.
That’s why we’re particularly enamored with these new Mac Caddy Jet & Plug Organizers from Trick Flow.
The trays fit snugly atop your carburetor (both 4150- and 4500-style models are available).
Not only does that make sure your jets and plugs stay close at hand, it covers your carburetor bore to ensure you don’t accidentally drop tiny jets, nuts, screws, or peanut shells down into the manifold.
But better still, it keeps your spark plugs and carburetor and/or nitrous jets tidy and organized.
Note the eight pairs of holes for the spark plugs too. That allows you to keep a second second set of gapped plugs ready on standby if you need them. It also means you can arrange your old plugs side by side in the right order to compare their condition in between runs—which can help a ton with your timing adjustments.
Finally, by having all your nitrous and carburetor jets arranged in a stepped sequence, it allows you to easily make incremental adjustments to your fuel/NOS mixture without having to fumble around the bottom of an organizer tray looking for the exact jet size you need.
And again, the Trick Flow folks include plenty of holes for spare jets too.
Ready to make your next ignition timing or A/F mix adjustment a heck of a lot easier? Toss one of these handy Mac Caddy storage trays in your race trailer.
