I had my burner out on Jan.1. and it is stil totally clean inside and the boiler is too.
Since mid June or so i've burnt 1500 litres WVO and gearoils with no issues at all.....

DieselG;

I have all the specs regarding differences in the camshafts and the exact measurements for camshaft placing.  To get to this point myself and my U.S. partner have spent a good deal of money - stuff that we will never get back no matter how many improved camshafts we sell.  While everything is completely documented you can appreciate that it is proprietary information.  My U.S. guy used some of the best (old as dirt!) racing camshaft designers to get to this stage.  As for documentation, what are you looking for?  I sent three 12/2's down to Tennessee to have them retrofitted, I do have a movie clip of one of them after the new shaft was installed. Let me talk to my U.S. guy and see what he thinks about releasing technical details.

I believe your success is from the wVo and the gear oil.

I have a new clean burn boiler that has only 125 hours on it burning about 1.4 gallons an hour.
It is run on WMO only and it is filthy inside with white-gray ash building up at a rate that I am not sure I will be able to make it to the recommended 750 hour clean out.

What I am saying is try only WMO in your boiler and then look inside after say 1000 liters.
I believe you will find a lot of ash from all the wmo addatives.

Wvo would have only the heavy glycerin and if your burner gun is very good it might consume it if the gun gets the flame hot enough. As far as gear oil that stuff is high in sulfur and my experience with that stuff says if the flame is hot and yours must be if you can consume all the glycerin in wvo then the gear oil will burn clean. At least when I have burned a few waste gallons in a steel pail it always burns very clean to my amazement.

Not trying to start a caustic fight like our friend spencer but I believe wmo is full of addatives that when burned in almost any burner or engine at high enough rates it will produce ash that is not helpful so to say.............

JohnF,

We are on this forum to share and hopefully improve the overall situation regarding these clone engines. While we are not after your trade secrets, we also do not see the point to bringing up this stuff unless the coversation is brought to some kind of conclusion - hopefully beneficial to the forum members! We can always go to the original Lister designed parts and replicate as well as anyone else, we do not wish to reinvent the wheel and do not feel the antiques need to be made into racing engines. It would be great if we could offer folks an improved product and I believe that this is certainly possible in many areas if we continue working at it. If you would like to contribute to the effort, we all applaud you. We will take whatever you offer with gratitude. Economically we already know that there is not enough volume to carry too many major changes in design, however we do know that camshafts could be sourced prior to assembly in India, or produced elsewhere under better control. It could be a nice option, especially for the twins, to provide a good alternative. Documentation would include precise before and after measurements to include fuel consumption and horsepower output at various speeds and perhaps some ideas for the alternative assembly methods. This is the type of thing I would go after to justify the extra cost involved with any of the modifications proposed.

Thanks for you input and consideration!

John, are the crank pins even 180* apart from each other in the Indian 12/2's?
