This is a set of all new HS2s! These are a larger and better built set of carburetors over the stock H1s (1-1/8") that would have come with a Bugeye, and these will fit any A-series engine.
INSTALLATION NOTES:
- If you have a pre-heat box on your exhaust manifold, it will be in the way for the linkage in this kit. You will have to find a manifold without a riser or switch to a header, which you can find by .
- In the center of these carburetors, there are two brass nipples which are for vacuum. For most applications, such as a stock engine, you can simply cap these ports with a vacuum cap. Sometimes, it's preferred to run vacuum line from these nipples to the canister on the front of a 1275 engine if you have a rear seal kit installed (). If you decide to go that route, you would run vacuum line from each nipple to a "y" in the middle, then run the single vacuum line to the canister on the front of the engine. Of course, every engine is different so yours may be different.

If you are swapping from H1 carbs, you will need new air filters! (links below)
These new SU carbs are beautiful and all you to start fresh with matching new parts with no wear.7
The HS2 is a superior evolution to the original H1 Bugeye carburetor. The intake throat is slightly larger so you get more fuel and air mixture into your engine but the linkage is much simpler and there are fewer moving parts which means less maintenance and more precise operation. Moreover, the design is improved so there are fewer rubber gaskets to maintain and less vulnerability to the corrosive affects of ethanol. We recommend HS2s as a significant upgrade over the original carburetor.
You get a complete assembly with new manifold and all moving parts, which optimizes your chances of getting the best tune. New linkage, new springs, and all new components are refreshing to see!
