Ok, I purchased a Redmax 2401 trimmer yesterday and have a few concerns. Is the 2401 a new product, because all i see on the previous threads are the 2400 -or is it simply in the 2400 series?? Also, I seem to be having some trouble warm starting it. If I try to start it again about a half hour after running it, it doesn't want to start - I have to go through the cold start procedure every time -- prime, start in choke and let die, then open it up and start. Anyone else having this problem? Also, it takes a while to warm up once it is started. I have to let it idle for 10 seconds or so before pulling the throttle, or else it dies. Lastly, it seems to vibrate more than I had hoped. Is anyone else out there having these same symptoms??
