I'm new here, and just bought a 2014 Symba that was running fine in the shop, but since coming home i'm having a lot of trouble with it: when first started, it idles OK, but after a minute or so it dies. When restarted, any attempts to give it throttle will kill it. This goes on for quite a while (10-15 mins), until eventually things are warmed up enough (I'm guessing) to that be ridden. It does this in the morning when temps are in the high 30s, as well as afternoons in the 50s and 60s. I pulled the carb, disassembled, cleaned it, but no difference. It's always possible i missed something in the carb, but is there anything else I should look into? The bike is stock as far as I can tell.
