Hey guys!<br /><br />Wonder if you can help me at all? I've spent about 2 hours on it now and me back is killing me!<br /><br />I have a small RIB with a Force 85hp which was only developing 27 knots so figured something was up. I removed the carb covers and found the throttle butterflies were hardly opening. <br />I have since fiddled with all the settings and buggered the whole lot up trying to fix it!<br />Could anyone point me in what direction to go to set up the timing etc etc. I presume there is an order to set these things up? I don't really want to invest in the workshop manual as I suspect it will never be used again and am normally pretty good with all things mechanical.<br /><br />Your help is greatly appreciated!
