The 241CM will hit the US prolly very late in 2013 or first of 2014, due to demand elsewhere.
The new "I" series saws (fuel injected) are going to be very simple to work on if they are the same set up as the 500 I Cutoff saw, you talk about instant throttle response, nothing like it exist in chainsaws today, very simple system, easy to diagnois and fix. People are just going to have to remember to pump the primer bulb 5-7 times before starting irregardless if it is a cold or hot start, fantastic set up, can't wait to see it on a saw, doesn't look like it is going to add weigh.
