Hey guys. My roommate's Blast has had this thing against starting while it's cold for some time. We never really did anything about it because it was always merely an inconvenience and because of her budget restraints. I'm curious if you could help me figure out what is going on with it though, because she will be selling the bike in the Spring and we'd like to get it working right first.
Basically, you need to open the throttle, press the starter, and roll the throttle off while you are cranking the engine to get it to start while it's cold. It has a carburetor but no choke. Cold starts are supposed to be aided by what's called an auto-enrichener which heats up as the bike warms up and closes off the extra air and fuel when it's not needed anymore.
To keep the bike idling, she has to keep the throttle on. It pops and hiccups the whole time too. To me, it sounds as if this auto-enrichener has failed. Once it's warm, the bike runs beautifully.
Any ideas? I'd just replace the part and see if it helps, but it's not my money. Before we go in, we'd like to be sure we're getting the right part.
