Oh, I was looking at the 8896-1 specs. I don't have specs for the 8896-2. Thanks for the update. I can see I'm going to have to do some experimenting. It had 8.5 power valves, so they were prob staying open all the time. The roller cam in there is pretty radical, and I doubt that it ever gets 8.5 " of vacuum, unless it's slowing down from a 10 second pass!my info shows the carb did come with 88 jets and 5.5 power valve.
Where's the timing? At 5200' elevation I would have 38 degrees minimum.Did you get any paperwork from the engine builder with the purchase? Might help you figure out or confirm cr
use a vacuum gauge to figure what you need. i'll bet the engine wouldn't run right because the PV was blown or leaking. this is easy to figure out.Oh, I was looking at the 8896-1 specs.

I bought this car from a lady whose husband had owned it, he ran it like 3 times, then got sick and passed away. No info from the PO or the builder. They claim it has 14 to 1 C/R which I don't really believe. They also claimed that it launched straight and was solid at top end. I doubt that too, as It had loose steering box bolts, and a bad idler arm.....As with any used car, you just have to go thru it, and correct the problems as you find them. I think it also has the wrong spark plugs. 440 Source says to use the Champion RC12YC, which are an extended reach. The ones in there are strange looking ones, not extended reach. So lots of problems to solve here. The carb fix has made some progress, at least now it will rev..Did you get any paperwork from the engine builder with the purchase?

The dist appears to be locked in at 38 degrees total. On the 1050 carb, I put 80 jets all around, and blocked the primary power valve. I had put a 2.5 in the sec, so I know it is staying closed when running at 2500 RPM., with no load. It is still running really rich. Won't run smooth out until I shut off the fuel pump, Then it smooths out in about 3 seconds, speeds up as it leans out, then shuts off as the fuel in the bowls is used up. During the time it smooths out, it sounds like an airplane engine. Firing smoothly on all cylinders. No blubbering. So I have gone down from the stock 88 jets to 80s so far. Should I go down to smaller main jets? I Changed plugs, and they were all black and sooty. Went to RC12YC Champions. Guess I will drop down to 76 main jets all around and see what that does. I am at 5400 feet, and most carbs need smaller jets up here. Any ideas?Where's the timing? At 5200' elevation I would have 38 degrees minimum.
