How to Rebuild a Tecumseh V60 Carburetor

Recommended Posts

Excellent detailed, correct rebuild procedure!  I think that 'jiggle rod' is the part that causes so many seemingly 'not repairable' issues that gives the Tekky carbs a bad name.

If a correct overhaul still presents troubles, I have found a simple two step 'fix' that works every time:

1. unbolt carb

2. throw it as far as you can.

Amazon. They are Oregon products. 7/16" and 9/16".

Bob where did you find this chart exactly? I've been messing around with an LME Walbro and I keep finding ONE AND THREE QUARTER on the main jet.

Your chart above makes more sense because I had to turn IN to get it to run better.

New to this forum - I just rebuilt a V60 in an IH model 60. I can't seem to get the metering rod out that you described.  The carb  "shakes", but I can't see the rod move. I am soaking in carb cleaner again to see if that helps. I have tried to poke it with a pick and needle. Any suggestions?  Thanks for a great post. I didn't remove the Welch plugs when I initially cleaned it. It ran well but dies after 5 sec or so.

Welcome aboard John.  

 

 

Perhaps @Handy Don can help out.

The metering rod, at least on the Tecumseh's I've worked on, are captive and cannot be removed (at least without abnormal surgery on the carb). If it is shaking, it is fine.

To run for 5 seconds and then die does sound like fuel starvation. I would test this by opening the idle needle jet a full turn and see if the engine limps along on just that fuel. If yes, then the main jet is still not working.

Funny, all the problem ones I had the idle circuit would not work - high speed and wide open was not an issue ...

I don't see what so unpredictable there.

They go up. Then they go up. And after that they go up.

Mehh...

Such is life.

I agree that many techy carbs deserve the sledge hammer, but not all. As to the fax machine, having been an office machine dealer for most of my life, most fax machines from that era do deserve the hammer.
