you can use a compression gauge take the gauge off just have the hose screwed in bump the engine over when it gets to tdc youll feel the compression shoot out of the hose just go slow. thats how i do it when im not sure about the timing marks.
ok, when the hose blows out I'm at TDC and I should line the next groove to zero. When your a TDC..it is not at zero by default correct?
