I would like to back up what Otto said about the nitro and oil thing. I have a .58CD and a .90SP and and ran each on WildCat 10% nitro Premium 16% lube and then on WildCat 15% Premium Extra 18% lube, they ran exactly the same on these two different fuels save for a little more oil coming out of the breather with the Premium Extra. Both contain about 1.6% castor.

Here is a couple of pics of my 90 which has 5hrs 15mins on it so far. I have attached an VP-30 perry pump to see how far the perry pump can draw fuel. In the pic is 57" of large tubing to the fuel can then another 12" inside. I have got the engine running with the pump but only for an couple mins so far with this arrangement as i'm still tinkering with the pump. But so far everything seems to work ok. I will only need to draw fuel through 40" of tubing, so i think drawing fuel through 40" of tubing will not pose any problems.
