I guess the better way of stating it starts better in the cold is that it starts more often in the cold as compared to when the ambient temperature is warmer. If it does start no matter the temperatureit seems to have a rough idle which the dealership didn't notice. Fully serviced to me was check and replace all fluids and filters. So every filter and fluid has been replaced.

Doug I am second owner. Original owner is my father in law. I had it fully serviced just to make sure that wasn't the issue. Original air filter was in great conditionas of monday. I used before the issue started about 2 to 3 times a week. I checked trail cameras and put feeders out for deer. But I didn't do alot of shutting it off and turning back on. Generally it was left running the entire time. I was putting fuel in it about once a month using the recommended octane or as close as I could buy. I also took it to the gas station so I wouldn't have gas jugs full of old fuel.

See where I'm perplexed is the problem occurs more when the machine gets hot e.g. a warmer day or the engine is hot. I have better luck starting it when it's cold.

It's got 150 miles on it. The exhaust smells rich when you try to turn it over after it dies. I have drained the fuel tank and replaced the fuel. There are unfortunately no codes stored either. I unfortunately don't have a lot of diagnostic tools at my disposal.

I have a 2016 CForce 500 HO that will sometimes start and run (does have a rougher idle than when originally purchased). Majority of the time the machine will start and idle for less than 10 seconds before shutting off. After that it will crank but not turn over. Getting fuel and spark. Took it to a dealership and got it back with a unable to reproduce the problem. Have rode it maybe 3 times in the past 6 months due to this issue
