#1 is the front passenger side. There is only 1 line across the balancer for TDC. Remove the number 1 plug, unhook the 12V to the dizzy, bump the engine over until your finger is blown off of the plug hole. There is a weak blow when it is on the echaust stroke and a stronger one on compression stroke. Then you are real close to TDC. The line should be near the pointer at this time. then you can line it up @tdc. If not, then the outer ring may have slipped on the balancer and needs to be replaced.
