Does not seem to be many posts in general but there is no posting in waste motor oils.
Am I the only person using it to generate electric ever day?
People say they are using it and then they go very quiet.
A lot people talk about generating there own power but 2 years on they are still talking about it.
If your using wmo as a main fuel every day in a generator lets hear about it.

The bottom has dropped out of the market.
Lister CS engines are nice but that's a lot of money.
Is a collector going to pay a lot for a Lister CS or is some one going to pay that much just to make a generator.
I think prices are going to come down,just like property.

My only thought was the white ash was normal when burning wmo because when my waste oil fired workshop heater is burning cleanly it has lots of white ash.
When it's not been burning cleanly it is sooty and black with no white ash.
I think the higher the ratio of waste oil burnt in a diesel engine the more white ash you will see if its burning it correctly.
I have notice if I just run on diesel the swirl camber is black.
This is why I feel that the engine has been running well when I see white or grey soot in the swirl chamber but I could be wrong.

The injector heater failed the other week so I have been running with out it.
Every day before the next run I unscrew the cylinder head bung and scrape out any carbon that has collected.
There has been no difference in the amount of carbon and the injector tip is keeping fairly clean just as when the heater was working.
I thought I would refit the compression change over valve and see what difference running in low compression would make.
I can also report that there is less carbon build up.
I think the extra air turbulence is moving the carbon and the engine run's smoother in low compression.
Before I started running my Lister on wmo I read what people where saying about wmo and they would say you need extra injector heat and to run in high compression and run the engine under a heavy load.
I am finding you just need a 2000 watt load and a thermostat and that's it.
But I have had injector tips carbon up in the past but I think the waste oil I have at the moment is working well but I don't know why. 
All I know is it's working very well at the moment.

I think I know what you mean.
The valves should be lower than the face of the head for clearance reason's.
So the seating part of the valve seat is the lower part.
Just grind them in a little and that's all they need.

If the engine is the same as the one in the picture it is a petter copy and  can be run safely at 2200 rpm

I have five petter engines of that type.

I use a oil measuring jug and put in one and a quarter of thinners like petrol, diesel, heating oil and add waste engine oil up to the five litres or us quarts mark.
Just give it a quick stir and tip in.
The oil is just filtered with sock filters.
I think that because the oil is black you just think its dirty,so when you can remove that preconception from your mind its not a big deal.
Removing the bung and cleaning the carbon that sits behind it is the only extra thing to do,if not it brakes off and the engine makes a nasty knock until it clears.
When I pull the engine apart next time I am going to set the bump clearance to that of a 8/1 and fit the appropriate bung so there is more clearance between the piston and the head for loose carbon.

Not really, Matt, I can remember talking to both David Harris and an operator of a single-cylinder FR1 genny, both said the same thing, it was marginal at best. Twins and upward had enough power reserves to get over the internal losses.

There's an FR1 on ebay at present.

As a prior owner of an FR1, I agree. Plus, it was a high-maintenance machine, and awkward to work on. An inspired design, but give me a CS any day......

The fr range of engines are not high maintenance at all.
You may have had a high maintenance engine if it was worn out .
They are Very good engines but completely different to a cs which is a very basic engine more suitable to the less experienced.
