I feel lucky for once / I start mine and go never a hesitation. (I know I should warm it up but I usually just take it slow for the first foot or two.)

Do you guys have the models with carbs? (Sorry / I am usually the one that has any available problem)
Did you shoot and barbecue that damn bush hog?

I have another idea back when I was a kid they always told me to take my 1968 Camaro out on the highway and go as fast as I could to burn the carbon out. I have done this with everything I own and my cars all have over 200000 miles and still run strong. If you baby an engine it just will not like it when you need to use it hard. I believe that if you ride around slow all the time the engine will never run to its full potential. I think the best thing to do is ride it like you stole it most of the time.
