I have a 6/1 running a 5kw gen set. I try to run it about 620 rpm and the genset is about 118-119 volt at that speed. Now , it will run along fine at that speed until the battery bank starts getting full and the rectifier reduces required amps at which time the 6/1 starts to gain a little speed.  Now if Sun comes out nice and bright and adds some solar into the mix then the rectifier reduces amps substanially and the Listeroid picks up more speed. 

So now The Lister is revving higher and instead of feeding 240 volts into the rectifier its sending in 250-255 volts and the rectifier won't accept voltage that high so it kicks off leaving the Lister to run unloaded and I have to catch it or will overspeed so bad its taken two cranks out!  Today I caught it in time and it must have been going 1000 rpm!  Where do I start? I thought the genset would maintain a certain voltage, but apparently its speed related? 

Hi Everyone,

 I'm looking for an injector line for a Lister CD. The line runs from the pump to the injector.

 Mine rubbed a pinhole in the side.  Anyone ever weld an injector line? Or will I be the first to try?... Thanks

Sometimes we get Lucky!
              I collect old Windchargers, generators, 6, 12 &32 volt stuff from years gone by. A guy called me this winter and asked if I was interested in some 32 volt motors, lightbulbs and old generator. I took his number and gave him a call last Sat to go have a look. I got real excited when he opened the shed door and there sat a 3 1/2 hp Lister /generator! Its rare to find one that complete, lots of times the generator was removed and engine used for a water pump or saw etc.
         He even had the magneto rebuilt so he could get it running. Its has a rheostat to vary the volts from 32-46, and the brass arm is missing off that,otherwise it is fairly complete.
              I'm not sure of the year, but I'm guessing early '30's? Serial #53929

Just got done replacing the crank in my GTC 6/1. Put in new crank, new con rod and bearing, piston rings are about a month old, had head redone with new valves and guides and seats.

 Fired it up today and it has a loud knock with a real high ring to it! It sounds as if someone is using a hammer and tapping  on the flywheel with every revolution. After pulling the side cover off and checking everything inside, finding nothing out of the ordinary I thought the piston must be hitting the valves. So pulled the head off, everything is good. Torqued the cylinder to spec and measured the piston to head clearance and its good. Reassembled and same noise!
    Thought maybe it was timing gear issue so pulled that apart and realigned the marks. Same noise. I'm running out of options. Everything turns over smooth and quiet by hand but as soon as it fires it starts knocking.
  As I was typing this I got wondering if the cylinder liner could have came loose? Maybe its moving up and down with the piston?  Anyone?   Thanks

I'm running my 6/1 on WVO,but I'm having trouble with carbon after about 4 days of running. I have made some corrections so it may get better. I heat the oil via engine coolant to about 160 degrees then have an injection line heater so oil is hot going in. I just added the line heater so this might correct it.
            When I pull the head off,the exhaust valve is carboned up as well as the top of the piston is fairly black and baked on, as well as a bit of a black ridge in top of  cylinder.
           I've tried the water injection method for a day or so, didnt seem to help much. I've running with the compression knob turned in(some people say you need higher compression for veg.oil) that didnt seem to make much diff.
         Next I'll try the Acetone mixture with the oil, see if that helps. I wonder what would happen if I used Lacquer thinner instead of Acetone? The ingrediants of Lacquer thinner are, Toluene, methyl ethyl ketone, methanol,and acetone. But its $15.00 a gal, compared to $28.00 gal for Acetone.
    Next question How much of a role would my exhaust system be playing in this ?  I have 2 inch pipe coming out of the engine with a sharp 90 degree elbow going straight up 3 feet then a more gradual 90 following the ceiling over to the outer wall about 6 feet, then through the wall and another 90 along the outside wall for about 2 feet into a Ford  pickup muffler then out of the muffler to another gradual 90 downspout.Total exhaust sytem is about 15 feet of 2 inch pipe but lots of turns. Is exhaust better to rise up out of the engine or down?  Straight out is not an option the way my shed is set up but I could go straight up through the ceiling or down to just above the floor then straight out. Or Maybe exhaust is not the problem.
               I am current oiling the valves and rocker arms with a veg-oil-2 cycle oil mixture just a shot a couple times a day. I think I'll make a felt washer setup on the valve stems so the absorb oil but dont let it get sucked in the valve guides. 
       

This has probably been addressed before, or maybe I should be contacting my supplier..but he is a man of few words most times.
         I have my Gen wired 240 volt, U3 and U4 clamped together, and U1 and U2 as Line 1 and Line 2. According to the book this wired for 50 Hz. (Should be 60Hz in this country) but there are no connections or even holes for U5 and U6.
          So now at my panel box in the gen shed I want to get 110 volts but need a neutral connection. Whats the procedure?  I have 3 wire cable to run from Gen to panel box.  Thanks

I have a 5000 watt Generac belt driven generator, while getting 4 inch pulley made a fellow commented it will take a few hp to run this generator. I never thought about it at the time, but could it be it takes more power to run 3600 rpm vs 1800 ?
        With my 6/1 running at 650 -652 rpm (using a laser tach) when I plug in a 500 watt halogen light(560 watts according to the watt meter) I immediately lose 10 rpm.
      By plugging in another 1000 watt load (heater) the engine slows and really labours. 1600 watts and I'm down to 600 rpm. In order to maintain 650 RPM I have to start unloaded at 690 rpm!
      Unloaded the generator is putting out 130 volts at 62-64 hz. With light plugged in it lowers to about 127 volts 60-62 hz.In order to lower those numbers  I'd have to slow the engine down.
     Sooo... Engine issue? or generator issue?  With 560 watt load the engine ran at 650 rpm for 3 hrs tonite, temperature right about 170, no thermostat. Thermosyhponing into a 20 gal tank of water.
