Holley 1909, 1 barrel carburetor and 2300 2 barel float spring & Holley 2280 pump return spring.

This spring goes between the float and the float bowl. This keeps the float from bouncing on a rough road.

1 1/4" height, 1/2-5/8" base diameter.

Holley 2280 pump return spring for some carburetors. Not all Holley 2280 use this style spring.

Holley 1920, these can be used to replace the original, but the top will likely need to be modified. Some springs had a pin on the top that attach to the float hinge to keep it secure.

Spring

These work, but have to be modified. The original spring had a piece sticking up that went into the float. The spring can be bent to work. This website talks about the importance of accuracy when buying a kit, but their springs are not accurate. But as i said it can be made to work. Should be noted in the sales section though.

Yeah had no idea where this went, the original had fallen out during disassembly and I hadn't seen where from. Also, the tip not having the little stinger sticking up didn't help. The drawing showing this should have been included in the pack. But overall a nice part, but I'm keeping it for the next one.

This spring has been working fine in my Holly for the past year. I bent a 4 mm tip upward and curled it inwards to center it. I had also installed a newer float from EBAY that weighs 12.6 g. Previous float was around 10.7 g after a LONG dry out. Turning off my hot engine does cause some gas to bubble and flood through the jet making a harder restart. I have lowered my float about 3\16 inch at shutoff and have not had flooding since. That newer float still weighed about 12.6 g after one year of use. Runs great and I expect much cleaner spark plugs.

Holley 1920 Float Spring

This is a very good spring and works perfectly for carburetors where the spring is missing.
