WRITE THE DATE CODE ON THE RECEIPT WHEN YOU SELL A CARBURETOR Edelbrock Performer Series Carburetor Warranty is 90 days, Thunder Series AVS Carbs is one year and all remanufactured Carbs is 30 days When a customer returns an Edelbrock carburetor, always match the date code and part number to the customers receipt Please take a close look at Julian dates for a correct warranty return If the date code is over 1 year from the day of return, it is probably not within the 90-day warranty period To help your customer with preventative maintenance always recommend that an “in-line” fuel filter be added when using an Edelbrock carburetor such as Part #8134 and #81343 for Performer & Thunder Series Single Feed, or #8133 and #8128 for Thunder Series Dual Feed. This will help prevent debris from entering the carburetor during installation as well as daily usage, thus reducing the chance of needless warranty return. QUESTIONS TO ASK What is the fuel pump pressure? Edelbrock carburetors need to be below 6.5 psi or the car will flood. Some stock pumps produce over 6.5 psi. Reduce pressure with the use of a fuel pressure regulator (not included) What is your base ignition timing set to? If you are running a larger than stock camshaft, you should set the timing to 10 - 14 degrees. What intake manifold are you running? Edelbrock carburetors are made for “Square Flange” intake manifolds. An Edelbrock adapter may be needed. Did you check for vacuum leaks? A weak vacuum will not idle correctly. Did you have a large camshaft? Any camshafts that are 110 Centerline or smaller, have weak vacuum and will require more ignition timing. Did you install the included fuel filter? (Part #1405 and #1406) You must run an external fuel filter to keep contaminants out of the carburetor When did you purchase this carburetor? Is it still within warranty requirements?

TRANSCRIPT

WRITE THE DATE CODE ON THE RECEIPT WHEN YOU SELL A CARBURETOREdelbrock Performer Series Carburetor Warranty is 90 days,

Thunder Series AVS Carbs is one year and all remanufactured Carbs is 30 days

When a customer returns an Edelbrock carburetor, always match the date code and part number to the customers receipt

Please take a close look at Julian dates for a correct warranty return

If the date code is over 1 year from the day of return, it is probably not within the 90-day warranty period

To help your customer with preventative maintenance always recommend that an “in-line” fuel filter be added when using an Edelbrock carburetor such as Part #8134

and #81343 for Performer & Thunder Series Single Feed, or #8133 and #8128 for Thunder Series Dual Feed. This will help prevent debris from entering the carburetor during

installation as well as daily usage, thus reducing the chance of needless warranty return.

QUESTIONS TO ASKWhat is the fuel pump pressure?

Edelbrock carburetors need to be below 6.5 psi or the car will fl ood. Some stock pumps produce over 6.5 psi. Reduce pressure with the use of a fuel pressure regulator (not included)

What is your base ignition timing set to?

If you are running a larger than stock camshaft, you should set the timing to 10 - 14 degrees.

What intake manifold are you running?

Edelbrock carburetors are made for “Square Flange” intake manifolds. An Edelbrock adapter may be needed.

Did you check for vacuum leaks? A weak vacuum will not idle correctly.

Did you have a large camshaft? Any camshafts that are 110 Centerline or smaller, have weak vacuum and will require more ignition timing.

Did you install the included fuel fi lter? (Part #1405 and #1406)

You must run an external fuel fi lter to keep contaminants out of the carburetor

When did you purchase this carburetor?

Is it still within warranty requirements?
