Timing chain drip leg?

hydraulic tensioners work well, but thy have no tension at startup, if you have a backfire on start or it kicks back, you are at the mercy of the chain itself with no tensioner, and sometimes these are flacid with no oil pressure and can cause a jump. My Honda was notoriou for doing that (bad carb and a very long chain). My mazda had a nice ratchet tensioner, it just kept getting tighter when it wore itself. My Breeze had one like that too but it was sort of a toothed cam that unwound a lobe. The MP tensioner and drip tab will work forever.
