onan carb questions (float)

Well I have a new (to me) GT-18 Hydro 917.257070. It has led a rough life and I'm doing some of the "routine" maintenance that has been ignored for some time.

I disassembled and soaked and cleaned the carb. I reassembled with the old gaskets and float and it ran great, for a while. It now runs like poop.

The next to do items are new fuel line from the filter to the tank, and a float for the carb (it has the "original" foam type float).

I have searched and it is recommended to buy the brass float.

My question is: should I buy the Onan brand float with the assist spring or can I buy the knock-off and get the same results?

The Onan float is about $50 and includes an "assist" spring.

The "off brand" float is on eBay. It runs about $25. It appears to be compatible, but does NOT have the float spring.

Do I NEED to spend the extra $25 for the spring? Has any one bought the knock-off and then had to replace it with the onan to get it to run right?

I'm torn...

Thanks for your responses.

the knock off doesn't need the spring.
too light in weight, and to many fitment problems
where do you think they are made?
thank you. boomer (the used onan engine parts guy)
