Jeff if you're only going to be doing the small cube carburetors then those in the 2.5L will work fine. just one with a heater as it makes the cleaning go faster. I use a 2.5 L for several years until needed a larger unit for the larger ATV and Briggs carbs.

Just be aware that carburetor kits can be as much as those cheap online carbs. Plus it takes experience in the cleaning and adjustment of these cube carbs. Sometimes you can get by with a gasket and diaphragm kit (GND) and other times a full kit might be needed.With experience you can get down to just replacing the metering diaphragm on some when cleaning. It always varies depending what is worn out. I am currently awaiting a kit for a Haulong HQ-2 as the metering diaphragm isn't available separately through Husqvarna. In this case both the carburetor and repair kit are the same price so it would been just as cheap to just replace the carburetor.

There are times with the market the way it is currently is more cost effective to replace than repair. I just don't like sending things to recycle or to the landfill when it is not necessary. And when come those el cheapo string trimmers they are now priced here at my minimum labor charge so they are not even being repaired just replaced. It is a shame that they can't be cost effective repaired but the customers just keep buying them anyway as they rather buy the alcohol and smokes.

For me I seldom were replace one these cubes; unless, it is badly worn or have internal failure that the OEM does provide replacement parts for. One note although places like Walbro may list the part as available getting is another story.

It usually takes about up to 4-6 cycles on the smaller units as most have 8 minutes max timer and it can take to 30 minutes on these small cubes.

As for disassembly you take it down the base cube but don't need to remove the welch plugs. The mixture screw(s) is helpful as it allows the cleaner access to backside of the welch plugs in the metering section. Don't high pressure to blow dry these carbs as it can do internal damage.
