You will need to run a pump and regulate your pressure to 2-3 pounds. There have been issues in the past with using these Weber carburetors with Mallory and FS distributors due to the advance curve being too slow in advancing.
They need lighter springs to bring the advance on sooner. To verify, remove your Mallory or FS and replace with a stock style distributor and see if the issue goes away.We recommend purchasing one of the Nu-Rex timing kits so your timing is set up properly giving you the ability to check with a timing light, the part number A-6252. 25 degrees max advance and all advance
