Hi, Duker.<br /><br />Thirty bux or so invested in a Service Manual would be the best investment you ever made.<br /><br />Your problem is most likely in the linkage adjustment, but could be in the idle circuit of one of the carbs.<br /><br />The "link 'n' synch" adjustment procedure described in the manual should clear up the problem and improve overall performance.<br /><br />Good luck.

I am surprise, oh Ancient One, by your lack of hospitality. You didn't even welcome duker to iboats. (musta' been a senior moment )It's OK....I'll do it for you. <br /><br />Welcome aboard iboats duker! Don't hesitate to post any questions you might have about your rig. And JB is on the money with his comments. Most of the time, an engine runs ragged cause it just needs a little tunning up.<br /><br />Good Luck.
