Hello. I recently joined this forum because I am at the end of my knowledge, and abilities. I was hoping that someone has experienced this scenario. I have a 1973 Ford 2000 tractor based upon the stamping on the body, with metric and standard bolts and parts from Great Brittan on the 3 cylinder gas motor. The carburetor was a Holley from a 3000 model. When I purchased the tractor it ran. Poorly, but it ran. The motor could not be pushed to accelerate unless done gradually. I was able to cycle through the gears of the 4 speed with a high & low. The wheel seals were leaking, and the assembly for the clutch pedal was leaking where it entered the body of the tractor. After shutting the motor off the carburetor leaked fuel on the ground. Enough to leave an eight inch round puddle. Ok. This is where I started. I purchased a carb kit and proceeded to deep clean the carb, adjust the float, and re-assemble with the new parts. Still leaked. Assembled and dis-assembled looking for my error. Found nothing. Fuel still leaked no change. The fuel was leaking at the bottom of the carb out of the air intake, and the built in drain. I replaced the Holley with a new Zenyth, because apparently the Holley could wear out and could not be repaired without sending it out. At best that was a 50/50. So I leapt with faith that the Zenyth was the answer. The motor ran better, fuel still leaked at the same amount and rate. As I increased the throttle the tractor would spit and backfire. I could not bring it up to speed at all. Ok. Next problem. Vacuum advance on the distributor was shot. Great! Can't buy a new vacuum diaphragm!! So I installed my new distributor with a mechanical advance. Success! Timing is perfect, throttle increase/decrease perfect. Looking good! Carb still leaks same amount! Checked pressure on fuel pump.. 5 pounds on the money. Tractor starts great.. runs great but it's running a little rich. This is pointing to the float level in the new Zenyth Carb. Before I open this new carburetor up to check the float level, can anyone tell me if I missed something? The fuel leak is coming from inside the throat of the carb body. It drips after I shut the tractor off. The fuel shut off at the tank works. I do not have the piping from the air filter on tight to the carburetor. I feel if I had all that piping buttoned up it may not leak on the ground. It would stay in the pipe, and the bottom of the carb. But that's not the way it should be. However, the tractor is still running rich. Again, this is pointing to the float level. I just find it odd that I have the same exact issue through two carburetors. Does anyone see anything that I may not have checked? Also does anyone know the float level setting on the new Zenyth carb for a Ford 2000? If I can provide any more information, please ask. I really appreciate any suggestions. Thank you, Robert
