Re: Johnson J130PLSS 130hp 2000 model
sorry to see the smart ones didnt pick this up. i wished i couldve been more help.<br />ill try to explain what mine was doing <br />-<br />it would start up no problems, seemed to run fine on muffs <by the way get yourself a flushing muffler>. but when i got it to the water would not go above 2000 to 2500rpm & then run fine. #2 plug was wet- but you could tell it was firing at times.<br />i also had excess oil running down skeg. so i took it into the shop had everything checked.<br />i got the call the power pack was bad. a new one went on- no more oil and it ran great.<br />-<br />if it was my motor<br />1- i would get an omc manual <br />2-compression test<not a bad idea to replace head gaskets or atleast retorque heads><br />3-change the fuel filter & inspect all the lines<br />4-clean all electrical connections, including coil bolts, ground wires<br />5-check for spark , plug wires for cracks, coils too. <spark tester should be set at 7/16 gap w/blue arch><br />6-remove airbox and pump bulb to make sure no fuel is coming out of the carbs & bulb stays hard<br />7-while box is off make sure all carb lines are good and connected. <primer/fuel> lync & sync throttle before you close up<br />8-check all recirculaton check valves & fittings <refer to manual> very easy<br />9-check pulse limiter valve <manual> easy<br />10-inspect/replace thermostats<br />11-inspect water pump & replace impeller<br />12-then i would run at nite checking for any spark arching. & remove each plug one at a time to see if there is a difference<br />-<br />of coarse if you can rebuilding carbs is a good idea. <br />if you still have a problem with just one cylinder try switching that coil with one from the opposite side, to isolate a bad coil.<br />-<br />this is time consuming but you will know more about your motor and save yourself $$$.<br />-<br />when i torn my 120/140 down to clean/inspect the parts to put on spare power head, you would not believe how dirty the recircualtion fittings were. as well as bad check valves.<br />i feel that should have been taken care of when i asked for a
complete bill of health- before i put into the water <i paid for it>. i now know where not to take my motor.<br />-<br />if i missed anything, i stand to be corrected. just trying to help.
<br />Any thing else i can check? Thanks for the help.<br />--Hop
