My son recently spent his 4-H money on a 1945 Farmall A, and we're working on it together. (Both of us are novices!) The previous owner said it was running 5 years ago, but has been sitting in the barn since. We have spark, and we have rebuilt the carburater, but still can't get it started. Yesterday we realized that the exhaust is sucking air in, which seems like maybe a problem with a valve. (Or a head gasket, but how would that have blown sitting in the barn?). So we opened up the valve cover and adjusted the clearance on the valves per the manual, but aren't sure what else to do in there, or what else we might try. Any suggestions? Many thanks! p.s. we haven't done a compression check, since we don't have a gauge.
