Carb? Johnson 115 V-4 from 1983

[RiverMan]

Hello...JB<br /> I don't have any electric going to the top cylinders and I even pull the the spark plugs wires with my hands.<br /> If the carb is the problem that will impede the electric to travel all way to the coils or plugs??? I also found 2 different powepacks on this engine.<br />One original from OMC #582125 with the old wiring(4 wires on halfcircle) and the other a Rapair # 3110 with the new wiring (3 wires on line and one up)so, the timer base has 2 diffrents plugs that fit each of the diffrents packs. The OMC is recomended for the 115 and the Rapair is for 120/140. If the problem is the powerpacks I should put the OMC required for this engine? Please, I will like somebody to explain me why the carb will be the problem. I did check all the voltage, replace fuel line and plugs, as I mentioned before. I will like to wait and clarified the carb. question until I spent $160 on powerpacks.<br />Any suggestions will be greatly appreciated<br />RiverMan

Riverman,<br /><br />You need three basic things to make an engine run.<br /><br />1. Fuel/air mixture.<br />2. Spark-at the right time.<br />3. Compression.<br /><br />If you don't have spark, that's problem one. Take them one at a time.

Hi, Riverman.<br /><br />Side by side cylinders do not use the same powerpak. They do use the same carb. <br /><br />Since you didn't tell us the whole story I made a logical, but incorrect, call based on wrong data.<br /><br />You obviously have an ignition problem. Fix that first.

I am not sure about the odd pack, but if the wires are connected correctly it should work. You have a timer, power pack,problem or both. You need a peak reading meter to check stator output, timer output, and pack output. The power packs have an isolation diode, if the diode is bad in one pack it causes the packs to interfere with each other. Check between termial A and D of each pack, with pack disconnected with ohm meter. Note the reading, reverse the leads, you should have one high, and one low reading.

The 3110 power pack is for 86/87 110 HP. Should work, but has to have 3 wires going to timer,2 wires to stator, 2 wires to ignition coil, and 1 wire for shutdown, and 1 for ground. How are you checking the voltage.

Hi <br />I did check packs wires A/D using a digital multimeter @ scale 20M<br />OMC reads 8.15 ohms; inverse: reads 1 .<br />Rapair reads 5.10 ohms; inverse: goes all way to 19.47 them back to 1 .<br />Tested 2 wires on stator Br/Y and Br: on each side reads 3 Ohms. Tested 4 wires from timer base A to B to C and D them everyone to ground. <br />Thanks again for you comments.<br /> <br />RiverMan

Disconnect the black/yellow wires from packs and try it. When you disconnect these 2 wires the switch will not stop engine. The specs for the 2 sets of wires from the stator/ brown and brown/yellow is 450 to 600 ohns. A better way to check this is with the engine running,with a peak reading meter, Check output to coil,from pack, charge coil to pack, timer/trigger output to pack.
