Fuel Cell Size?

One more question - do you run foam in yours? I'm wondering if they make an ethanol-compatible foam.
No foam. I will not use foam, I’ve read it kinda deteriorates and I’m just not willing to put up with something like that, if it happens.
I use pump gas 91, highest available in the state of CA, and I just don’t feel like it’s the same fuel from even just a few years ago. It really has an odd smell as it burns, and not as easy to tune, but I am an idiot when it comes to carburetor adjustments. I kinda cheat, and have my brother do all the tuning.
