          So I probably have bad news, No.1 is at 140 psi, No. 2 at 130 psi, and No.3 at 120 psi. Kenny said all 3 were at 145 psi when he built it (16 engine hours ago....)

          I would like to get everyone's opinion on whether or not pump 93 octane is sufficient for 145 psi...

          Thanks!

            Well, the engine is apart now....those light seizures amounted to a complete catastrophe...

            No. 3's wrist pin bearing came apart and chewed up the piston, cylinder, and dome...

            Metal got in No. 2 and caused just as much damage...

            Flywheel bolts came out and chewed up the stator and magneto...

            All this and the pistons and crank were SBT whereas the seller told me the engine was built with an OEM crank and pistons....

              Can you point me in the right direction to make this right? Do I have to take it off and grind the mounting tab to the grate to make it flush? And I just used 3m 4200 on the eye glass seal area. (Black area) Stock grate for pictured for reference.

                Yes, if your fitment isn't to your liking (i.e. it is hanging down a bit) then you have to gradually take small amounts off those mounting bosses to allow the plate to suck up a bit "higher" in the hull. I remember my Shredmaster specifically coming with instructions that said you might have to do this due to hull-to-hull manufacturing variances. It is also recommended to re-check the fit after each incremental material removal b/c it is easy to get it all caty-whompus and end up in a situation where only some of your bosses are touching the hull mounts. Honestly, mine was a real time consuming PITA to get right. You don't want it to have a bunch of assembly stress from uneven mounting induced warpage. I hope that makes sense.
