40 Farmall A - I have tried switching the plug wires. We just had the head cleaned and valves seated. I have worked with the timimg for days. We bought new plugs and wires. Nothing I do or have done stops the popping back through the carbureator. BUT, when I take the last or #4 plug wire off, the 'popping' stops. Any suggestions? I'm thinking a broken cam shaft.

Sounds like the exhaust valve on #4 cylinder isn't opening, maybe camshaft lobe flat?

if the cam was broke it would not run at all better take the valve cover off and hand crank and check each and every pushrod to make sure it is opening the valve then set the clearence in the krder the cycl fires starting with #1 the one closest to the radiator on compression stroke then on down the order of firing which is written on the block change spark plugs with another cycl that you say is ok then you will know if you are in time ,have the wires right, and valve clearence set might want to take a compression test after all this is done then you will know nothing is caught in a valve holding it open

Sounds like you need to readjust the valves....the intake valve is not sealed ,when that cylinder fires,,,,thus, fire comes back through the intake valve and into the carb......

Did you set the valve clearance when you reinstalled the head.If improperly set on that particular cylinder it can cuase the popping until you pull the wire.To check for broken cam look and see if the rocker arm moves when you turn the engine over.IF they arent then its broken.

Today's Featured Article - Tractor Implements and Their Use - by Curtis Von Fange. Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he reached his early sixties ... [Read Article]
