    Have always ran the AC Delco R43T plugs. Now Autozone says they are unavailable now. They have a R43TS that has an extended tip (the post and electrode stick out about 1/16" further than the R43T) The rest of the plug is identical in geometry/dimensions. I'm running a small dome 10:1 piston...

  6. Trump and the abortion issue.

    Political Rhetoric
    I’m so sick of this abortion trap. If you performed one on stage or blew up a PP you will always be on the wrong side. Mr Shiver up his leg led Trump down a path to get a sound bite (it was Trumps fault he fell for it). I’ve talked to a few women yesterday and asked them, If there was a law...

  17. Starter Issue

    Is there an issue with using one of those GM Trans Spacer and a standard cast iron nose starters? I had to grind some of the nose of the starter just to get the bolts started. I think it put pressure in the starter and it chewed up the bushing and housing itself in just two outings.

    New to the jet boat world but I have been bitten. I have a BBC with logs running through the transom. I bought the boat and the last owner said it took a long time for the boat to warm up after you get it into the lake. It does take awhile, but it does warm up to about 150 degrees. I was on...

  20. Obama to issue EO granting clemancy to illegals

    Political Rhetoric
    Yup, reported today zero is preparing an executive order to grant clemency to the thousands of illegals flooding across our borders! That will surely stop the influx of illegals, NOT! If this happens, will this be '' the straw that breaks the camels back '' and starts zeros impeachment?
