Echo Garden - Recent Questions, Troubleshooting & Support


You need three things for the engine to run, a good clean fuel supply to the piston, a good spark at the right point, and a cylinder and piston in good condition with adequate compression. So start with the easy inexpressive, things first, drain the fuel tank and pull the hose and filter out through the filler hole in the tank, replace filter if dirty, re fill with fresh fuel mix. Remove the spark plug, earth it against the cylinder, crank the engine to check for a spark. Remove the muffler and check the condition of the piston face through the open port, any sign of scuffing and further investigation will be required. After cranking the engine, does the spark plug look wet, if not we have a fuel supply issue, so there maybe a blockage in the carb, so remove the carb and service. these are the basics before getting into more diagnostics.

You need to strip and clean the carburetor. The main jet is blocked.

The choke and idle jets are fine.

carb needs cleaning jets plugged

Start by replacing the spark plug, fuel filter and air cleaner (believe they make a kit containing these parts for this purpose.)

Also you need to pull the muffler and clean the spark arrester. My suspicion is its partically clogged. Just pull it and either replace with new (if bad) or hit it with a small propane torch (or hold it over a gas burner on your kitchen stove using needle nose pliers) to burn off the gunk.

You most likely lost one of the two long bolts that hold the muffler tight to the engine or you could of lost one of them.

On all 2-cycle motors there is a screen on the exhaust muffler. These motors need 3 things to run and they are fuel, spark, and air. Now to get air flow it has to come in one side via the air filter then out the otherside throw the exhaust. These screen are put there for admission i just remove them. To locate this screen look at the muffler do you see a smaller metal peace attached to the muffler it is attached with 3 #2 phillips head screws. I you make sure the motor hasn't been running first the remove these 3 screws and remove the small metal peace you will see the screen just remove screen then reach the small peace of metal with 3 screws and it should run fine.
