I rebuilt my carburetors using the original hard parts but replaced all the o rings. I've had nagging carburetion issues and have traced the problem to excessive fuel in the bowls. I used the clear hose attached to the bowl drain method, and discovered that the float valves aren't shutting the fuel off, even when closed. This lets just enough fuel get into the intakes, to cause hard starting and plug fouling, resulting in an inability to make proper adjustments of the carbs. I'm pretty much resigned to the fact that I need to replace the float valves. My question is, what aftermarket brand do you guys recommend as QUALITY replacements? I'd love to buy the Honda ones, but they're 100.00 for 4. Thanks in advance.
