I'm just getting mine on now but one thing I found after setting the floats per spec is my rear cylinder wasn't getting fuel from the accelerator pump. They went back to Sudco twice and they reported no problems but finally suggested that I tweak the rear float level. I didn't measure it but I just set it for a higher level and now finally I have both pumps working in tandem and it's starting easier.
Wondering if maybe others are having a similar issue since I'm hearing a lot of "It started running on one cylinder..." about starting. Just a thought.
