I'm in need of a carb for my '74 Atc90. I'd like to get an original 90 or 110 carb, but I can't seem to find one reasonably priced. So I've been looking at getting one of these carbs. http://dratv.com/19waca.html but I don't know how good of quality these are, and how well they work.
So has anyone used one before?

I bought this one for my ATC90:

http://dratv.com/19ctcafik21.html

It seems to work ok, but I've had two problems: first, the float has been extremely difficult to adjust. It seemed to me the fuel bowl is very small, and the adjustment between starving and overflowing all over the garage floor is very tiny. Second, I mentioned this in another post, since I used an aftermarket air filter (also from DrATV), it gave a noticable increase in power, but it's very fussy to start in cold weather. Maybe I need to move the needle up, or to rejet...

I know, your original question was not about that carb. If you end up buying it, will you please post the results? It's a very inexpensive carb and would be worth a try!

I just put a atc 110 carb on an atc 90, I changed the main jet to an 85 and its perfect though you will need the stock air cleaner to use that main jet. If you use a different air filter you may need something bigger.

If I can't get an original 90/110 carb for a reasonable price, I may just get that cheaper one for DrATV.
The problem is that I'm not sure if the machine I'm buying the carb for is worth putting a carb on because it's missing a few parts.
