Above, you can see a plastic carburetor float half full of fuel. This one came out of a Bugeye with HS2 carbs and overflowing float bowls.
Ethanol is an excellent solvent. It’s also a good drying agent. With the advent of ethanol in gasoline, we see a lot more plastic floats full of fuel. That’s a real problem with British cars, because the floats need to float in order to keep the carbs and fuel senders working properly. Rubber parts are impacted too.
You can find a list of ethanol-free gas stations by clicking here. But such fuel not available in all areas and in some cases, it’s very expensive racing fuel with higher octane than what is needed for most stock Sprites.
We recommend changing floats to the nitrophyl on HS2 carbs. We’ve never had a nitrophyl float fill with fuel and sink.
Plastic fuel sender floats are also a problem, these seem to be the first to fill-up and sink, so make sure you have a brass float in your fuel tank as well. And off course, you have to make sure the new float stays attached to the arm on your sender.
