No fuel to carb

You rebuilt the carb? could the metering diaphragm be installed upside down? (THE ONE WITH THE DISC) or could it be the lever connected to the needle isn't set to correct height? Zama and Walbro have great web sites. one more thing are you sure you put the fuel lines (2) on the right spot?? one line goes to the filter the other is simply a return and only goes in the tank but not too deep into the fuel

Gas leaks into cylinder causing engine to siege when not using, can remove plug; pull rope and gas blowes out replace plug , pull rope blower will crank. Thanls Billy

Hi Billy. This is a problem with the float needle in the carb. See this link page 10 (Item 24): Also item 15. Most likely there is either a hole in the diaphram or..... there is debris in the float needle seat that has to be removed. This is not a difficult repair but... it is tedious if you have to remove the float needle.

There is a repair kit for this WALBRO WTA33 carb. The part number for the kit is K10-WTA. See this link:

Most local lawnmower shops have these kits in stock but... ordering on line can save you time and money for the parts search.

I am most certainthat if you clear the debris from the float needle seat and the diaphram is good that your leak will cease. If you clear the debris and you still have the over-night / between use leak.... the diaphram will have to be replaced. All it takes is a pin hole over time for the cylinder to fill up.

There is a Walbro carb for the WT series "Service Manual" here:

Just put a new cylinder and psiton on an Echo

Pin hole in fuel line can cause lean running condition. Also, be SURE the fuel is fresh and 89 octane or higher. Stale fuels can will give you pre-ignition and detonation issues that are nearly impossible to chase down. Ethanol blended or Oxygenated fuels are a NO-NO in high reving 2-strokes!
If fuel type and fuel line check good, go to carb inlet needle settings and then on to carb passagways.
