You probably have the needle in the carb not shutting off or going back to shut off the fuel. What you need to do is rebuild the carb and most lawn shops can sell you a kit to do that. You can see videos on as to how to do it if you are not familiar with the rebuild process it is not hard to accomplish. The kits are around $8.00. Hope this helps.

SOURCE: I have a Echo PB/251 Gas Blower which I recently

Check the muffler and/or spark arrestor screen in the muffler outlet pipe and also the engine's exhaust port behind the muffler. These are prone to carbon-clogging and the engine cannot "BREATHE" enough to reach full throttle. If all-clear in the muffler, go back in the carb and locate the inlet screen directly opposite of the inlet needle. Carefully pull it out with a pick and hold it up to a light source. If you cannot see thru it, replace it. This is another, (less) common area of obstruction.

Hope this helps,

Echo pb 200 new carb, plug , filter , lines ,grommet starts and immediately dies

You might have the fuel lines crossed. Or a leak of air into the gas tank. It’s a fuel problem for sure if it starts and then dies.

Wont stay running, replaced spark plug and air filter, starts but wont stay running

Try mixing fresh gas mixture, any fuel over 30 days old is gone bad, this may help. Or the carburetor may need rebuilding, or the exhaust screen on the muffler is clogged up. Remember before taking anything apart use either PB blaster or Deep Creep on the bolts before loosening them.

Air Filter soaked with gas

Clean It with soap and water and afterwards let it dry and put a little bit of motor oil on the filter. You may want to check your petcocks because they may be leaking. Be cautious when you ride with a gas soaked air filter the airbox may catch on fire if the motorcycle backfires which I have experienced in the past.

Starts but wont stay running

Check your gas filter. When you ran out of gas, you got any rust in your lines and filters. Change the inline filter and use an air compressor and blow the line TOWARDS THE TANK. Take the gas cap off first. There is also a filter in your tank.By blowing the line you may unstop that filter.

I have an echo gas powered leaf blower, model pb251. it will start and idol, but wont run any faster than that, and throttle cable seems to be ok.

I just fixed my Echo PB 2100 with the same issue. It would start, run, all throttle openings OK but would not rev-up. It was a dirty/clogged screen on the muffler. Scraped the thick tar off then used Lacquer Thinner to soak it clean. Blower works better than ever now....
