View Full Version : no start!

12-10-2006, 03:28 PM
My 0-320 finally said no to me and refused to start. I ordered new plugs, installed them and she fired right up. I thought I had solved my problem. Six hours later I wanted to make a trip to the Brazos river........again the cub refused to start. Annual time so I removed all the inspection covers, removed the metal belly, engine cowling and pulled it over to where it was to be annualed. That next day my mechanic called and said the slick mags were off 12 degrees. I wondered how they got off 12 degrees? I always thought my cub was a hard starter. Any thoughts? Thanks teeweed

Maybe the mag's hold down bolts loosened up and allowed the magnetos to rotate changing the timing. After this annual fly for awhile and check the bolts for tightness.

Add this to your toolbox!


Put this on after the bolts are tight so you can tell if they move.

Scribe a mark on the accesory case and unto the magneto. That will let you know how much your points have worn over time. Mag to engine timing should be checked at least every annual and usually has to be adjusted.

Could be your points have a big tit on them. part inside is *&&%$# up or any number of things. Anytime mags get off more than few degrees One should investigate why, not just readjust the mag.

Stop it, you guys; you're killing me! I haven't laughed this hard in years.

Oh, wait. That wasn't funny at all.

Really hard to believe that both mags decided to change the same direction and the same amount !!!!!!!!!!!!!!!!! Wish I could get such odds at the casinos.
