I set the timing as advised earlier in this thread. It wasn't even close! Also...

there was a slight stumble upon lght acceleration. I pulled the air filter and noticed there was a very slight leak at the accelerator pump. I thought there might be some dirt stuck in there so I disconnected and plugged the fuel line. Then I ran the fuel out of the carb. I blew some compressed air through the fuel inlet, then, reconnected everything. This resolved the leak and the "stumble".
