Hello to everyone. Seems that you all have some people that know a lot about all kinds of outboards and I am hoping that yall can help me out. I have a 1974 Johnson 70 HP 70ESLR74M on the back of a 1995 Javelin 15.5 foot bass boat. It has been sitting for a number of years but has been run on muffs even while sitting. My father in-law gave my wife and me this boat and I knew that it would be a fixer. It is in pretty good shape overall but needs a little TLC.
I have purchased new 2 batteries, new fuel tank and supply hose. Put new plugs in. Been through the fuel pump, lines and pulled all of the carbs and stripped them down and cleaned and rehabbed them. Everything is free and free flowing. Now, on to the problem. It ran perfect on muffs with everything done in the driveway. You can about look at the key and it will fire. When we took it out, it was a different story. Once in the water, it would idle ok (it has always idled a little fast according to my father in-law.) When you try to give it gas, it sputters out and dies. If you rev it a few times and then let it settle and then put it in gear, it will take off and run without issue. We ran it for a while running 30mph without issue. Stop, and then a fast start, it would take off. If you stopped and idled for a bit, it would die.
Now, we started running everything the way he ran it when he parked it. The adjustment on the carbs was turned all the way in. I was wondering what these should be set at? I have not found anything thus far for an average setting.
Next thing with it, once we got it back, it revved up and would not shut down. After messing with it after killing it at the carbs by choking it out, we found that the timing bar(?) under the fly wheel was creeping up and not coming back. we have tried some adjustment for that, but nothing is bringing it back to where we have it set at idle. We are having to set it back by hand to bring the idle back down.
I know this is a lot and if you have made it this far through all of this, any help would be greatly appreciated. Thanks in advance. I just want to go fishing!!!
