Well thanks for that! Perhaps I should explain better. I own a two cylinder lister generator and wanted to get a clearer idea of consumption. I came here on the off chance of finding some useful information with regard to fuel consumption of the Lister engines after an internet search throw up your site, but I found the information rather varied so I searched on the internet again and found the owners workshop manual for the lister engines I mentioned. I thought that it might be of interest to someone here what it said so I went to the trouble of registering simply to pass on the information I had gleaned.
I am not into boating though it does attract me, however as I expect you will say why don't I just run my generator and measure the fuel consumption. Since it is fed from a 100 gallon tank that is not that straight forward but I will make up a small capacity tank and couple that up direct to the gen set and get an accurate measure of consumption at a certain loadings.
Cheers
