Tecumseh needle seat

My buddy who runs a cycle shop fixes anything with engines. The last month has brought in several blowers for help. One had the same Tecumseh 8hp as my tracker. It gave him fits for a while. Ran on spray but not picking up gas. Pulling carb again and flipping it over showed non adjustable float not even horizontal. Float level too low so no pickup. The composite needle seat had swollen like so many bits effected by our wonderous pump gas. The bean counters strike again! A rubber tip needle with a metal seat costs minutely more times many means-"Let's cut costs again!!". Perhaps this isn't news to some of you but it was to us. GJ

To each his own,I guess.I've never bought one of those Chinese made PsOS and never will.The original Tec. carbs are way better quality.I will always rebuild.If I absolutely can't get one to perform(rare),used ones are plentiful.

Not trying to start a riot,just my opinion.

Welcome John. Yeah, carbs can be a hassle to tune, but to me that is part of the fun. I usually rebuild carbs, especially the older adjustable ones. But I have the time to do so.

And my view is that the "bean counters" are not mostly to blame for less durable parts, but rather the average consumer these days, that just wants cheap prices. The customer dictates the market, not the maker. And again, the average customer wants cheap, not repairable. But you'll see that many on this forum are not "average" consumers, and they have alot of knowledge to share.

my $0.02.

That's a real common problem with the needle seat and easily replaceable. The part is very common and not expensive, and very easy to replace, especially if you have the tool to do it.
The needle seat "Swells" and it will make the float level too low so it won't get fuel or enough fuel to the jets.
Its a lot easier and cheaper to replace the seat than it is to replace the carburetor.
