I have a blaster II 760 that does not like to start after it fires and dies. It will usually start the first try but if it starts and dies it will not start. I have had the carbs rebuilt and it runs fine after started. This happened to me this weekend in the keys. It started with no problem on Saturday but on Sunday it started and died twice. When I pulled out the choke it did nothing. I thought I may have flooded it so I changed the plugs with new one but still nothing. I poured a little gas in the carbs and it started right up and ran fine the rest of the day. Should I use the choke when I start it cold no matter what or could something else be the problem? THANKS
