I'm thinking that if I have a diaphram/pumping carb. and using a starter, do I need/want a choke? It's a 3W-50 in a World Models Extra300, mounted inverted, and I'm building it for someone who has no large gas engine experience (I don't have much) and we don't want to flood it, or maybe hydraulic it...Won't just using the electric starter eliminate the need for the choke? If I had to just hand prop it, then I'd seriously consider using it , but...It should start and warm up O.K. w/o it shouldn't it? Thanks.
