I have a dual carb ea 81 now, but I have to rebuild it. They are hard to find in the US, but some surface around here from time to time. My friend purchased one from a website years ago. I am rebuilding his old one. The website he bought it from is in Japan, but now asks you for a vehicle and the year of vehicle. I had an ea 82, but had bad luck with the timing belt. It sucks when a timing belt breaks in the middle of the marsh. I am currently running a regular ea 81 with a weber.
