switched to k&n pod filter and took baffeling out of the pipe and need to rejet the carb but have no idea what to get and if i need a needle too. i live right at sea level if that matters and help would be much appreciated

I run 55/155 with the 2 washers in place of the white spacer, K&N and drilled Dyna. I'm about 400' above sea level. It might be excessive but it doesn't smoke and I still get around 50 mpg.

If re-jetting doesn't get rid of the shotgun blasts, you can try removing a small amount from the spring in the TEV. I clipped about 1/8" from the length of the spring (half a round) and doing so seems to have completely eliminated shotgun blasts on decel on my stock 2007. But I'd rejet first. The 55 pilot and adjusting the air mix screw might be enough to get rid of the backfires.

One of my favorite jets



Sadly, theyre old & have been thru so many take off/landing cycles the airframes just dont pass muster..I was told it was originally designed by Cessna as a small business jet, adopted by the military, modified to handle the job.But I cant find anything to back that up.
But,, reading this its pretty clear the "business jet" notion was BoguS.. Or without the OGU,, just BS..

I never woulda thot those little planes were so heavy! I saw them  fly & do strafing runs when I was in the AF. I helped maintain the scoring system at the range,,so, I got to see a few types of fighters shoot their guns at the targets,

The one I showed is Much harder to get & runs a LOT more fuel thru it,
