Daylight proved to be the problem, couldn't see the small spark. Found it but it still would not fire. Put a small a,ount of premix in top cylinder and it fired up tight off. Ran it for half an hour whilst fiddling with mixture and eventually got so low on idle it died, and damned if it would not restart that time. It had several other times. let her sit overnight. this morning, several pulls, no firing. Removed top plug and added some premix, fired right off and stop starts ok thus far.
Reason for rebuilding carb is this is a new motor to me and the first time out I experienced some erratic operation, which after removing the carb I found to be a broken cam follower, but decided to go through the carb since I had no idea about the condition. It was pretty clean actually. I also have a water pump kit to rebuild it just because I don't know the condition and here in AZ they don't last long. I notice that while running sometimes debris plugs the pee hole and a small wire clears it immediately.
When running she seems to be a smooth little engine, but when it won't start its a bear.
