One more plug for George at : He's written a wonderful artical (About 80 pages long) called Lister Longevity. He suggests that folks buy it before they get into one of these engines, and I'd have to agree. Some manufactures do a better job than others, I think mine falls somewhere inbetween. (George knows which ones are good, which are bad.. and which are a good gamble!) "Lister Longevity" goes into a lot more depth than his pages at , and it not only tells the reader what they may be getting into, but it also details lots of assembly/disassembly proceedures - lots of tips on improving them.... the document in my opinion makes the engine a much more valuable thing.
Focusing primarily on the supply of alternative energy equipment including the legendary JKSon Lister type diesel engines, ST alternator heads in single and three phase.
We are currently putting the equipment in the field to generate off grid power for our own use and research purposes. Some of the JKSon engines lend themselves to experimentation with waste vegetable oils and vegetable oils produced on farm.
These engines are not turn key solutions but require a certain amount of mechanical ability and offer a rewarding DIY experience - these slow revving engines are produced in a developing country at an affordable price and will deliver long life if they are cleaned and checked prior to use.
They are a simple cost effective power solution to run a myriad of belt driven equipment - spare parts are readily available and at a reasonable cost.
