Roosa-Master Surprise, Surprise

Decided pump was probably due a retread. Surfed the www and found a guy in New England that only did pumps for his living. Discussed removal and transportation to him.

In the conversation he said to loosen the inspection plate just above the ID tag and let some fuel run out while the thing is running. If the engine recovers you have one of two problem: pump or return line obstruction.

In short, I did and it did. Cleaned up the return line to the tank and HOT DOG!!!!! Runs like a top.

So just like is said on here repeatedly, it's not always a complicated solution to a problem.

So now did I not only avoid the big bucks and inconvenience of removal and shipment and return, but I have use of my tractor in this, the start of the haying season.

Don't remember the guys name but would like to thank him.

Hope someone gets some lift from this.

Many of the systems from the 50's and 60's did not have a housing pressure regulator in the return line . If you have one in the return line, then his advice is correct , if you don't have one , then you had better find out what caused the line to be blocked . Usually blocked by the pieces of the governor drive ring that has become old and brittle and has shattered and floated out with the return fuel. If this is the case , some where in the near future you will cut off the rivots that are in the gov drive plate and at that point you no longer have any governor control. You don't have runaway engine, you have over speed engine and runaway operator.

My green 4020 started spitting parts in the return line and when it did it got an overhaul. Forget now how I finally decided the pump was my problem, i.e. what was I doing inspecting the return line. But got it fixed over the www also (place in the carolinas) and they did an excellent job, fast and all for a reasonable price.

Thanks for the tip
