making good progress

Today Adam and I got a good bit accomplished.
We initially fired her up and he already said that it was running better. We ran a timing gun and the light was no where near what it needed to be at 15deg for TDC. I know that I that I installed the CAS correctly. So we unbolted the valve cover and saw that the marks on the CAS were correct. So we rotated the crank pulley 1 full revolution back to TDC and the CAS was not alligned. Again we rotated the crank 1 full revolution and the CAS was in allignment again. So we concluded that there is a 1:2 ratio- so 1 full revolution of the crank = 1/2 revolution of the CAS. So we concluded that the CAS as 180deg off. We rotated the crank pulley again 1 full revolution and realligned the CAS. Bolted up the valve cover and tried to turn her over. No go!
So, how I initially had it was correct. So set the motor to TDC and pulled to valve cover off again. Rotated the crank pulley 1 revolution and reallign the CAS. Bolted up the valve cover. Fired her up again. She started up and was holding idle. We put the timing gun to the motor and it was almost on. A little adjusting of the CAS and she was hitting 15deg with the timing light. Yay. Much better. She was still running rich with black smoke and a little rough however still able to hold idle at 750rpms.
We then noticed a little smoke coming from the engine bay on the exhaust side. Again, it was the same water line that I had to tighten a last week that is very difficult to get to because it is located between the 2 turbo housings. The leak wasn't a drip, but was enough to very slowly drip and burn off. The motor was hot so we weren't able to address that.
Next we move onto switching out the new wheels that I bought for the car. We took off the driver's front wheel and bolted on the new one that was already mounted with tires. Before I torqued the lug nuts, I attempted to turn the wheel, however it was rubbing on the coilovers. The width and offset was the same as the old wheels: 8.5inches wide and 35mm offset. However, the new wheel had a 235 width tire whereas the old, 225. This was the cause for the rubbing. Luckily, Adam has 7-8mm spacers at home. We will revisit tomorrow and mount the front wheels/tires with the new spacers.
Also on the docet for tmw is to address the leak and we are now to the point to employ professional help. Adam has a local buddy who has dealth with SR, RB and a plethora of high performance motors/cars helps us out before I hook up with Martin for tuning.
