Ford 3000 Timing

lucwhite · Sep 16, 2023

I finally got my 1973 Ford 3 cylinder tractor running with new parts for the distributor, but the timing sounds way off and even when I try all the way
slowed and all the way advanced, when I rev the engine it spits and sputters. It idles fine, but once I give it some gas, it revs up nicely, and then after
about twenty seconds, it start misfiring and popping, etc. I know I have the distributor aligned correctly, but no amount of adjustment seems to make
a difference. Could this be a carb issue? I cleaned out the carb last week and it looked fine. However, when I pull the choke lever, you cant even tell,
the engine sounds the same. I thought it might be the main jet adjustment at the top of the carb., but it doesnt seem to do much when I adjust it. If
someone has some advice, I would appreciate it.

Be a good idea to set the valves, then set the timing to factory specs , not playing with the distributor this way and that way. After the points are set to spec.also.

Can you describe how to check valves? I am a beginner mechanic and am not familiar with valve placement like which are the intake and which are the exhaust when firing order is 1,2,3. Thanks

Some guys are very regimented when it comes to their approach towards an engine that is giving problems. Setting the valves for him is easy so he does it and YES it does eliminate some problems that may keep your engine from running. Also it is a good maintenance item that needs done periodically. I really do not think in your case it is causing it to run bad after a short period. I would suggest checking the fuel supply. I believe this tractor has a fuel pump. Pull the line off the carb and crank the engine should get good pulses of fuel out line, at least a 1/4 cup after 5 seconds of cranking. If you find the flow is minimal which would really be only a dribble the way your engine is responding you will have to figure out where it is blocked. If that is good reconnect it an open the carb drain and crank engine again. Should get good flow there as well but somewhat less because of the restriction of the float needle. If only a dribble there pull the fitting that screws in the carb the feed line attaches to. It may very well have a fine screen in it that is plugged.

Are you using a manual as a guide to the required settings or just winging it? If so what manual? What carb do you have?
