Most time it require install new diaphragms when you clean a 2C carburetor as are usually harden from age and the fuel addtives used.Once new parts are install the metering lever usually need setting to the correct height. These are easily damaged during the cleaning process if you don't know how to clean them properly.

Good here though a lot of the carburetors are now fairly inexpensive to replace depending the equipment they are used on.

You are definitely on the right track. There is only one thing that could be wrong as long as you replaced the needle valve, screen, gasket, & diaphragm. When cleaning the carb., you need to clean the small portals incarb. with a Den Tek Brush, (used for cleaning between teeth), they work great for this job. These portals, if blocked slightly, can cause this problem.

you need to adjust the high speed needle turn it out in 1/4 increments as you throttle it, low speed may have to come out alittle but do high speed first. I had to answer this as I use to have a pastor john in sturgeon bay, miss him alot.

SOURCE: It won't run prorerly

I had the same problem. I took it to the dumpster and used my old echo that I purchased in 1986. The Homelite was 2 years old. My sugesstion is to dump it.

Sounds as if the Carb needs to be cleaned out. Get yourself a can of non-chlorinated brake cleaner and spray the carb out really well. Then reinstall the carb. Also check any ports in the carb to make sure there isn't any debris blocking the flow of fuel. I would also suggest getting some Stabil Marine (blue) fuel stabilizer. The ethanol in gas destroys small engine carbs. Just mix this in with your gas tank the next time you fill up. How old is this fuel? The ethanol also absorbs water, so even while in the gas can it is obtaining moisture. The Stabil Marine formula helps lesson the effects of the ethanol.

My Weed Eater FL1500LE gas leaf blower will not run beyond the full choke setting. If I move the lever to half choke the engine will stop. Or if I move the throttle from full throttle to a lower speed...


This is a tell tale sign of a lean fuel mixture. By choking the unit you are manually creating a richer fuel mixture. I would purchase a compression tester from a local parts store and check compression. If that's ok, I'm willing to bet the problem is still carb related. Two stroke carbs are tricky to clean because of high/low ports that are one way and sometimes impossible to clean. Did you remove high and low needles when cleaning carb? Another trick is to mix seafoam with your gas, then mix two cycle oil to proper ratio. Use 2 ounces seafoam to one gallon of gas, then mix two cycle oil to proper mix. Hope this helps! Good luck and happy wrenching!

It is obviosly fuel starvation, have you actually replaced the fuel filter on the end of the hose in the tank? try richening the fuel mixture by unscrewing the H and L screw on the carb 1/4 turn on each, you may need a special tool to grip and turn these.

Pb-413 blower. starts w choke, then stalls when choke is taken off. wont run at full throttle without choke on about 90%


Most likely there's a problem with fuel supply - choking cuts air supply optimizing the air/fuel mix. Most common solution is to check and clean the carburetor.

If there's a tiny fuel filter in the fuel line between tank and carburetor check it on excessive pollution. Replace it when necessary.

When opening the blower for carburetor cleaning - also check the airfilter and replace when dirty.

If never opened the blower - take pictures with a digital camera at each step. The pictures can help with assembly after cleaning.

Starts and idles will not run above idle unless choked. Have cleaned carb multiple times new fuel filter new air cleaner and cleaned exhaust screen new plug. Maybe a collapsing fuel line?


Hi,
Have you tried adjusting the carb? There should be two screws on the carb (hi & Low) turn the hi screw completely until it stops and then start the unit. Let it warm up and then begin to back the screw out until it starts to run smoothly but strong. Once you have it running then put it in full run position (choke) and you should be good.
Good luck!

Engine will only run with full choke on, engine stops as you open choke.


Check the fuel lines for cracks/breaks. If they are o.k., then:

You will need to disassemble the carburetor and spray with carb.cleaner. Make sure the small screen is free of debris. (Should be able to see daylight through it.)

Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152),to clean the small portals in carb. These portals can become blocked. Reassemble and start.

If the carb. parts are more than 4 years old, you may have to replace them.

If you need further assistance on:
1. Fuel line replacement or
2. Carburetor kit replacement

Just let me know.

Engine keeps flooding out


Recommend completely draining the fuel system. Tank, lines, and carb. Make sure everything is clean and dry. Clean or replace fuel filter. Always try to store it with a full tank of fuel. It is common to get condensation when the weather goes from warm to cold and back.
