Really like the solid TPI throttle response, chrisp and clean everytime, except when you start the machine on cold mornings. Other posts I’ve read share a similar cold-start issue. I’m far from an expert on this new machine, honestly, I don’t quite know what to do when it won’t start, but, I have found one thing so far to share. Seems the vacume system on the new 2-stroke is very sensitive. One solution, make darn sure that the air filter is clean. A slightly dirty filter is enough of a change to keep it from starting, or fouling a plug. Cheers
