Luke,
That's exactly what I did. Have a helper turn off the engine for you and be spry about looking down the carb throat. You'd be surprised how fast a winter gas blend will evap off a warm manifold. I also suggest you google this issue (both search in this forum and on the stovebolt website) - you can also tell if you're having a problem from drivability issues. Most of the discussions however are regarding multiple carbs and heat. You also need to make sure you don't have a leaky needle and seat. A drippy bowl will have you chasing ghosts. Great looking truck. I have to poke you bit... only one pic!?!?! Post more please. The exhaust does look good. How about a pic of the engine? Also, where was the pic taken? It looks nice. Good luck.

How were you able to look inside the manifold to see if the fuel was puddling? I'm guessing you turned the engine off turned the throttle and shined a light down? I routed my dual exhaust through 2 flowmaster 40 series out both sides of the truck near the end of the running boards. I used those rectangular camaro exhaust tips, it looks pretty neat under the running boards. heres a picture of it https://picasaweb.google.com/lh/sredir?uname=118055119004871558672&target=ALBUM&id=5867644479319753489&authkey=Gv1sRgCMPfsL-euKrsOQ&feat=email thanks again, Luke On Mon, Apr 15, 2013 at 12:18 PM, Allen Jones <jone...@myuw.net<mailto:jonesal%40myuw.net>> wrote: > Luke, > > > > Your message is a little confusing in that there's no such thing as an > "original header".
