I've recently read alot of bad things about the MDS 40 I was going to put on my Avistar.<div>Like the break in period, too high of idle RPM's and too low of Max RPM's.</div><div>Could I put an Enya 45 I have on it?</div><div>If so, how do I clean old engines??</div><div>The throttle wont even move. :P</div>
