Any progress Grover? I am curious because I have a Roch B on my 261 that just overflows and dumps gas everywhere. So dangerous and it was after a correct rebuild. It doesn't do it all the time though. Something is getting stuck every now and then. The last thing I tried seemed to fix it. The floats were getting caught on the gasket sides. I haven't run it enough since then to be 100% sure it's fixed. These days I clean, test and clean and retest after a rebuild to make sure things are right. Didn't used to have to do that back in the day. Dunno.
