Now that I have my rubber bands on my tractor, I can attempt to pull start it since I have ruined my elbows trying to crank it.
I took apart the sediment bowl and carb today. The new sediment bowl did not work properly so I got an old one and cleaned it out and it works great.
I took apart the carb as well. I need some guidance on these operate. Forgive my terminology and correct me. I took apart the inlet bowl. I have a good float and it seems to move freely. I have the pointed end of the needle pointed up. It bolted down tight and does not leak.
My carb is clean and all little holes in each piece seem clean. I bolted down the upper carb lid onto the top of the three carb sections. The top air mixture turns nicely. I put the mid and bottom sections and bolted up the carb tight.
After putting it on and tightening it up, I turned on the fuel. No initial leaks. Finally, after leaving the fuel on for some time, fuel was dripping from the copper line that leaves the upper chamber to the mid chamber. Is this where the fuel should enter the carb. It would appear that the float is not able to shut the flow of fuel. Is this correct?
I think this is also going on with my other tractor so now I need to learn the details of the carb. The fuel drips into the mid section from the copper tube and loads up the carb and backs up into the air intake.
At the end of the long day, I did redo the timing, spray a bit of starting fluid into the carb and got a nice fire on the first pull. I think if I get the carbs working better, I'll have these two gorgeous tractors running well soon.
Thanks for any help teaching me the carb and ideas on what to try next! Dave
