A turn of the crank and the A purrs to life!

Well I guess it wasn't quite that simple. I finished reassembling my '47 A on Christmas eve (Q&D rebuild, rings, bearing, valve job etc). So I went and filled the radiator, installed the plugs, added gas and started cranking. The best I could do was a sputter, with the engine just puffing a little smoke on each crank... So I grabbed a can of either and sprayed a little in the hole in the manifold right above the carb (has a little plug in it if that helps), and she fired right up, for a few second... Well did the same thing two or three times and pretty much determined that I had a carb issue. Now give that this is the carb I just rebuilt for my other A (the 41, read below), I went and found the one that was on the 47 (which has been sitting in kerosene for about a year and a half). Drained the kerosene out, installed it, and 3 cranks later it sputtered to life. Given it took a few more cranks and some fiddling with the choke to get it to run, not all that bad. I must say that having an engine you rebuilt fire up for the first time is quiet a thrill! So, now all the goodies, great oil pressure, the cylinder pressure is back up to where is should be, and more importantly even, and not a puff of blue smoke in sight. So after retorqueing the head I took it for a spin around the farm, I must say it felt like a victory lap!

So back to that faulty carb. It was on a 41 A that a friend gave me. I have been trying to that old girl going for a while. The carb was really gummed up so I bought a rebuild kit and did the usual clean and replace. When I installed it on the tractor it did the same thing, just little puffs of smoke. I assumed this was due to the low pressure on the number 2 and 3 cylinders (stuck rings I hope). Well now that I know that the carb isn't helping, where should I go next? Sounds like it's starved for fuel to me. I didn't reset the float when I did the rebuild, and it seemed a little on the low side (that is it would shut off quicker), could that be the problem? Maybe I'm asking to much, that is having two running tractors that I worked on. :)

Thanks!
