Re: sick 1978 mariner 140hp
I am running alittle more oil than 50:1. I run one bottle that says mix with 6 gallons to achieve 50:1 with about 5 1/2-5 3/4 gallons just for safety. The oil I use is quick silver, not the synthetic just the regular two stroke oil.
As far as the trigger goes, when I took it to him I had a cdi replacement trigger in the engine. He said that when he brought the non missing engine up to high rpms and the back to idle the cdi picked up a miss. That being said he pulled my cdi out and replaced it with a old oem type. I took it to the lake with that after he "fixed" it the first time and it would run ok just cut out like the switch was turned off. It would always start right back though. I took it back to him and explained the issues and he R&r'ed the trigger with yet another used oem one. It doesnt cut out and is te one currently on the engine
As far as the carbs go, he took my clogged up set that I took to him off and replaced them with another oem used set. Here again, I take the boat for a test run after he "fixed"it and she won't plane at all. She won't even build no more than 1500 rpm with the fast idle on the trailer out of the water. I take it back to the mechanic and he says he looked at my carbs that came off and thought they needed a cleaning and also he found out somebody "tuned" the engine with the old clogged up carbs so he rebuilt them and put them on it. He also mentioned they have 80-81 jets instead of the 70sometging the engine came with. He mention that it has the same jets as a factory 150 has. All that being said he put the "tuned" carbs on and got it back to me. That's is when she ran, and she ran awesome until I had a gut feeling to verify timing and idle mixture. That's when I found the settings I referred to in the first post. All out of whack to say the least. Sorry about the general area on the jet sizes, I not sure the numbers I just know he told me they are the same as came in a 150 hp
