Re: general fuel question
Great explanation Zantz, thanks.<br /><br />UPDATE.....<br /><br />I took it out to the lake finally to check out my mechanical prowess. In a word (or two) I SUCK AT THIS!!<br /><br />It sounded better than before and it would run with a bit more throttle than before but once you committed to go all the way it died. Now, I could distinctly hear a little more cough or sputter before it died than before so that makes me think that it is more of a mixture or setting issue than the short that we talked about before.<br /><br />I need to play with the carbs a little more. I kept trying to adjust them each time it died and I finally wore my battery out and drifted across the lake for about 15 minutes before finally getting a tow back to the dock.<br /><br />Once again though, I found (after the battery was dead) that the bottom carb was not opening. That little connector between the two carbs came unhooked again. Could this be the only problem? Or on just one carb should it still throttle up and maybe just not perform just right? <br /><br /><br />Before I noticed this, while I was puttering, I went back to the motor and flipped the throttle on the top of the carb with my screwdriver and it reved up further. I couldn't do this much obviously because I was by myself. <br /><br />The next time I can put it on the hose in the driveway I'm going to disconnect the throttle from the bottom carb and see what kind of difference it makes and see if I can duplicate the problem without the load.<br /><br />With the throttle lever barely forward in gear, if you go back and rev it with the screwdriver, should the boat lurch forward? Or does the lever going more and more forward affect more than just the RPM?<br /><br /><br />Any and all help greatly appreciated.
<br /><br />Yes, the bottom carb not opening will make a big difference. Basically, with the bottom butterfly not opening, you are only running on one cylinder. <br /><br />The throttle lever also changes the timing as it opens the butterfly (long word, I'm shortening it BF for this post), therefore just flipping the BF open with a screwdriver would not have the same effect as using the lever.<br /><br /> I have a question to pose to one of the experts in here: <br />Is there a sync-n-link procedure on a Merc like there is on an Evinrude?<br /><br />JD, the reason I ask that question is:<br />with the BF in the vertical-closed position you have no flow (actually just very little), with the BF in the horizontal-open position you have max flow. The BF has the ability to go past horizontal, if it does, you are no longer at Wide Open Throttle (WOT).<br />Does that make sense?
