Step 11: Tune
Check for these these things:
over stressing parts (trying to make them do more then they want to do)
Basically add some oil (not much, but some) adjust parts that are causing problems, and keep everything sealed up tight. Also, we need to counterbalance the displacer.
First, go ahead and glue the other PVC piece down as well as the peanut butter top. Pull out the fan weight (or the penny or whatever) and start gluing it around on the wheel (use doublestick tape until you find the right spot) until you get the best preformance. This will probably be opposite the bend in the crankshaft, but not necessarily.
You're done go run your engine!
