I should have thought about this before - the fuel line in the tank was broken. Put a new fuel line in and I got the bulb to prime. Still doesn't start however. Haven't checked for spark and I do have the "-" set to on position. Ideas. The tiller did run with the old carb - but badly.

When I replaced tubing on a primer bulb carb, I used what I thought was common sense, but I turned out to be wrong. Fortunately Loger had a nice diagram for a similar unit. My primer bulb PULLS fuel through the carb by sucking fuel directly from tank to carb and then onto bulb and back into tank. Did you actually mark the lines and ports, or have a diagram?

BTW: re your other post; I have a Troy Built Horse but still couldn't figure out what a TB 144 was. Young people with less experience, and old folks like me with missing brains shouldn't have to deal with an ever increasing pile of undefined initials. By the way, BTW means 'by the way'. Yes, I know you knew that.
