With the exchange rate factored in, that's about what I spent to rebuild one of mine. Rebuild kit, new float and idle tube from CIH, bucket of carb cleaner, assorted sealants and what-not came to a bit over $100 USD. If you factor in the time to do the job, ouch! That carb is in excellent condition, $150 may not be such a bad deal. By comparison, new carburetor for a Tecumseh engine will run $50-$100.
Go for a stroll through Home Depot and take a gander at those 'green' machines selling for $3K. That puts a bit more perspective on the $$$ factor. I doubt many of them will survive much over 10 years, but there seem to be plenty of 50+ year old Cubs doing quite well.
Sorry about the main jet...I wanted to keep it original.
Pretty easy to get it to look like that. Not as easy to make it work as good as it looks.
Did you wire brush that? Mine are clean, but they sure don't shine like that!! Nice job. I bet the tractor it goes on looks equally as good.
I did wire brush, but only after a dip in a muratic acid bath. I mixed 1 part muratic to 4 parts water and then let it sit for awhile. The carb will turn a nice shade of gray. It shouldn't be left in the bath too long. Once the carb is removed from the bath rinse and rinse and rinse with cold fresh water and then rinse again.
Then use a brass wire brush and you'll be amazed at what happens.
The carb in the picture is just as clean on the inside as on the outside...which, is the most improtant.
This is an old family secret so please keep it to yourself
