I have a TEA20 (# 195174) and have been running it on and off for the last few years. After a few months of the tractor sitting I decided to give it a good clean off and examination - it started up ok but then I noticed it was cutting out probably due to gas starvation. The fuel line is a flanged metal tube that runs from the sediment bowl around back of the engine and joins in to a rubber section about 7 inches long that passes behind the carb and then connects up to another metal flanged tube that enters the carburetor (Zenith).
To investigate the fuel starvation I tried blowing in one end of the fuel pipe and there was a bit of air passage but not much. I passed a length of string trimmer line down the pipes and found a blockage in the rubber section. There was a slight bulge in the rubber about two inches from one end.
I thought this might be accumulated junk from the tank but I could not budge it. So I bought new rubber fuel line and cut open the bulge. The blockage is a cylindrical brass plug about 0.25" long with a chamfered end that looks like a jet but has no threads, just a tiny hole down the centre. My question is "Is it supposed to be there?"
How it got there I don't know. I don't recall fuel starvation being a problem before. Maybe the hole is big enough that in normal work enough fuel passes, but it would only take a small item to clog it.
