Can you use wd40 as carb cleaner?

WD 40 or a trusty degreaser like PB Blaster will be just fine at getting rid of the factory gunk build-up from newly made tanks. A lot of the time these are a hybrid of polymers and softeners. Once in a while, a tank might have some plasticizers, which you'll want put through the dishwasher or scrub down.

To answer your question about using wd40 as carb cleaner, it will get the job done as long as it's not some kind of hard-to-clean goo that is in the tank. If it is, then I would scrape it off with a putty knife and use a degreaser like PB Blaster.

For future reference, I've tried and recommend using PB Blaster. It was created for this exact purpose, and it has worked for me every time.

Conclusion

A carburetor is an internal combustion engine component used in most vehicles. It’s what mixes air and fuel and puts out a clean and consistent burn that will also match the engine speed (RPM). When a carburetor is clogged, misfiring occurs, and it will result in reducing power, some loss of fuel efficiency, and you may begin to notice a bit of smoky exhaust.
