My 1975 MTD 990 is in desparate need of a carburetor. My engine number is 326431-0139-01. build date is late in 1974. I have tried all my local shops here in Nova Scotia but to no avail. I do want to spend the money on a new one (yet) becasue I have not had the tractor running enough to make sure there are no other major issues. Can anyone help me. Thank in advance

Is your carb beyond rebuilding? What is the issue you are having with this carb? There are a couple issues with these carbs but If you take your time rebuilding you can fix it yourself. biggest problem is when you put it back together the top half has a tendency to be warped, (it's a bad design) and if you don't fix it will leak gas bad, the other issue is the metering tube that the high speed needle sits against tends to not seat well and causes fuel to come out the bottom of the carb ( acts like a stuck float) if you have any of these symptoms then you can repair the carb, rebuild kits are cheap for these. Let us know what type of problem you are having.Maybe we can help walk you through. Good luck.

I just noticed you replaced the mixture screws, did you rebuild it already?

Sorry i thought you said broken, that will teach me to read slower and more carefully, explain what the carb is doing (problems), what you have done to it (rebuild?), is this a new problem or has slowly become a problem ?
We can help, it's not hard to find parts for thoses and we have used ones kicking around.

P.M. Chris, thanks, im half awake.

I am located in Chester Basin on the South Shore of Nova Scotia................ and unfortuneatly the bottom bowl is stripped out (at needle valve), and either the upper or lower piece is warpped enough that I have at least a 1/16th of an inch gap. Along with that the throttle is very worn and loose. I was told not worth trying to rebuild, but try and locate another one. The bad part is, when I purchased my MTD990, the carb was shot and before I put out for a brand new carb ($$$$) I was hoping to track one down to make sure all was well with the tractor. Thanks Richard
