If you are having trouble with burning through your welds on thinner metal you may want to try a thinner wire. If you don't weld thin metal enough to justify buying a spool of thinner wire then you can use a piece of copper or brass on the back side of the weld. A steel weld will not stick to copper or brass so an old trick is to hold copper behind the weld to support the puddle. The copper or brass will also help dissipate the heat away from the weld so you don't have to turn down the amperage as much and you can weld quicker. It also helps keep the back side of the weld flatter and reduce any dressing work you may have to do to achieve a flat surface over your weld.
Thanks for the welding tips, next time I'm at the scrap yard, I'll have to try to find a piece of bronze or copper to use for that. I usually use .035 flex core for thicker metal, but I had a left over spool of .030 flex core from my trailer project that I was using on the air breather, probably still too thick of wire. I was able to do a series of tack welds all away around, it felt pretty strong, I just used the black silicone to seal the seams, heres a couple pics of it finished. The pic on the right I had to pound the air breather cover out to allow more clearance for the carb, it looks pretty crappy, but at least I can run a filter until I have the funds to come up with a better alternative.

I use 0.030 flux core wire to weld my 22gau rockers and floor, it works good you just can't have a continous weld, just a series of tacks. Hold the spool gun at a 45 degree angle to have less heat and hold it about 1.25'' from the metal, wait about half a second between tacks and weld on the side of the last tack where material is a bit thicker (if that makes sense). I am by no mean an expert but that's what I learned from youtube videos on body repairs lol!
