Echo GT200R clonking out, bogging on me

[diskotekka]

It started to do this and I had it sent out (twice) to get the carb rebuilt and cleaned.

The guy said he did the best he could and that the next step was to buy a new carb. Is this true? Are there other things I can do. The carb is rebuilt and clean, so I don't know what other recourse there is. I don't want to get rid of it as it serves me well and is a well built machine!

can you be more specific in your description? What exactly is it doing? I am a huge fan of that particular trimmer. In my opinion it is one of the best available for small yards. Echo equipment tends clog up spark arrestors quite often. One symptom is when trying to accelerate the engine will bog down. Sometimes there will be a build up of oily sludge on the exhaust and engine cover. On the other side of the coin, it may have an RB series Zama carburetor. There are quite a few guys that have trouble "overhauling" those carburetors. Sometimes it is not cost effective to overhaul them for customers anyway. Carb kits are usually around 10-15 bucks. Add another 15 in labor for the overhaul and usually end up close to $30. Some of those carbs are only $30 to replace.

When a customer brings one of those trimmers in that has fuel delivery issues I always do the following:

Remove spark arrestor
Clean or replace air filter
New spark plug
Replace fuel lines, fuel filter, and tank grommet
Overhaul or replace carburetor (depending on which carburetor, if its a $30 carb it gets replaced. saves headaches for the customer and myself)
