Hello, I just got this mini outboard I have some questions. First time on any forum also I'm not to sure how this goes Can anyone give me a link to where I can get a new diaphram? My fuel line falls off very easy I don't think it's correct. Where can I get the correct one, I got it running briefly there's is airbubbles in the line when I push the prime button. It starts then dies after a few seconds, unless I repeatedly push the prime button to force fuel in. Lastly I need a fuel cap mine spills gas everywhere when it runs. The one on it is from some sort of bottle. If anyone could help me I'd appreciate it, hard to find much info on it.
