After cleaning my carbs.. just the bowls and carb

Well, a couple things may be wrong.
1) debris could be lodged under the needle valve. Remove the float by gently slideing the float pin out, the needle will either slide out with the float or remain in the seat and a pair of needle nose pliers will help to retreave it. clean the seat and inspect the needle valve for damage.
*note that even the smalles debris can keep the needle from seating so take care during reassembly*

2)depending on the type of carb cleaner used, and the exact type of needle valve in your carbs, the needle valves may have been dammaged during the cleaning. Some carb cleaners can "eat" neoprene or rubber components in carbs. It is always best to fully disassemble them before cleaning, if you are not confident in your ability, have a pro do it for you.

The solution for this is to remove the needle valve as above, and inspect the needle and float for damage. **If in doubt replace the needle valve**

Good luck.

It acts like it is flooded, starts with choke off and throttle depressed. runs until carb runs out of gas then dies

Yes, Your carburetor sounds like it needs cleaned. Or you may possibly need to purchase a carb. kit for your trimmer if the cleaning doesn't do any good. When cleaning the carb. use a Den Tek Brush, (teeth cleaning brush), to clean the small ports. Also, check the small screen in carb. Can get clogged easily.

Cleaning Carb Jets

You shouldn't have to adjust anything as long as you don't increase the jet size and put everything back the same way it is removed.

Carburator cleaning

The First thing you have to NOT DO, is try to start it if it has been sitting for any long duration of time, 6 months or more, second, you have to remove the gas tank, drain the contents, into a can you can see in, look for a dark brown colored corpusal, in the gas, if there is some, that is an indication, that your carbs need to come apart, unless you are a seasoned mechanic, you will have to remove the carb, take the bowl off, of course you will look for the brown couloured substance again, clean the bowl,remove the pin, holding the float in placebeing carfule to secure the needle valve in its proper place after cleaning it thouroughly, remove the jet, using a tiny bit, you reem the jet hole center, taking care not to bore it out, the you run the bit in the jet hole, cleaning any debri that may be there, use carb cleaner and keep spraying it in all in puts and out puts the carb may have, then if you put your mouth to the feul input to the carb, blow in it to be sure it is clear, if not youl have to use carb cleaner and air to clean it out, air and carb cleaner is the key to cleaning it properly, some carbs need to be taken apart and soaked in a carb cleaner, before reassembly, just keep blowing air in all the inputs and out puts, to be sure they are cleared, reassemble and GO
