It lobes with or without load. Cleaned airfilter, drained float bowl, checked oil, fresh gas

As it appears the fuel pump functions, I suspect either the carburetor float is stuck or the carburetor bowl has mostly filled with water.


First drain fuel bowl. If you capture fuel and transfer to a clear glass container, you may see a water line develop within a few seconds (water on bottom fuel on top).


After fuel empties from bowl leave drain open and crank engine for a few seconds. Additional fuel should flow from the fuel drain. If no fuel then likely the float is stuck. Remove and clean fuel bowl. Check the float and/or inlet needle is not stuck.


If you found water in the fuel bowl, drain fuel tank and refill with fresh fuel. Check all fuel containers for water. Give the fuel container a thorough shake, and pour a sample into glass container. Look for visible water line.

Make sure there are no vacuum leaks on the engine manifold side of carburetor. There are 3 o 4 pieces on the engine side so inspect well.

If no leaks on engine manifold side then likely there's a blockage somewhere in the carburetor high speed circuit. Most economical solution is chinese knock-off for ~$20 US delivered.

If you can't find a cheap replacement then you'll need to do a deeper clean of carburetor by removing welch plugs and submerge in carb cleaner. You will need new welch plugs (kit) and likely kit will cost more than a knock-off carb.

Before tearing down carb, you could try Seafoam fuel treatment... probably less the 50:50 chance it will clear.

turn on device and wait for response inspect every component for malfunction

Gap the plug at .030 What is most likely the main problem is whatever gas sat in the carb. Even with fresh gas there will be some old gas still in the float bowl. You may be able to drain the bowl and be OK but I have a feeling that the carb will need to come off and be disassembled and cleaned properly. You can try spraying carb cleaner (I dislike starting fluid as it is too volatile and carb cleaner does just as well in this instance) into the carb/intake. Remove the air filter, open the choke, and spray the carb cleaner in through that way if possible. You can actually keep an engine running by spraying with short bursts. Even by just spraying once you should be able to get the engine to start. If it does start but then will not stay running without spraying more into the engine then it is a carb problem.

This is a relatively easy SELF correction process. Mind you a pool is FRESH water.

1. Drain all gas by remove the hose that connects to carb and completly drain the gas tank. (If there is an in line fuel filter or glass debris bowl, change filter / empty bowl.
2. Remove float bowl nut and bowl and purge water. Spray carb with carb cleaner while float bowl is removed. Paying particular attention to the float bowl nut thread area (throat)
3. Drain Oil. AFTER step 5.
4. Pressure Pump oil should be fine as it is not vented. (depending on pump installed but none of them are vented.
5. Remove spark plug and put about 1 ounce gas directly into the cylinder IGN OFF! Pull recoil and let gas exit spark plug hole. Reinstall a NEW spark plug BPR5ES or similar
6. Service engine oil
7. Fan dry the unit over night. Simple floor fan will do. Leave the gas cap OFF / float bowl open overnight during Fan Air dry.
8. Next morning service gas tank
9. Select fuel on and let a small amout of gas leak before installing the float bowl and nut making sure the float bowl gsket is installed against the top of the float bowl.

Final testing time... Ign. on.. Test spark first. Spark check good. FUEL ON. Start.

Just make sure to change oil again in 10 hours. Water in oil will cause the oil to appear milky.

You can do this. Worst case the electronic ignition module fails. (They are cheap... !) Most of the time the coil will not need to be changed.

That is water de-contamination 101 and you just completed the course. Give it your best shot. It beats buying a new one and yes it is worth repairing.

Thanks for choosing FixYa.

P.S. Oil the TIRE / WHEEL bearings.

Remove & Check Float bowl on carburettor for any foreign matter. If there is any, it could have got into jets causing engine to run lean (only run with choke) and not be able to carry load in this state. A cleanout of the carby would not hurt and check the fuel tank for any sediment as well.

G'day, sounds a bit like the float valve in the carby might be stuck nearly shut or just some moisture in the carby, a light tap with the handle of a screwdriver on the side of the carby bowl should fix it if it's the needle stuck shut (happens from sitting sometimes), or maybe try loosening the drain screw in the bottom of the carby bowl to drain any water etc out, hope this helps :)

on the bottom of the carb. is a bolt that holds the float bowl on. remove that bolt and float bowl. use a small needle and stick it in the holes on the bolt to clean them out. look at the gas in the float bowl to make sure there is no water in the fuel tank .

the engine is not getting enough gas. when you hold down the primer you are bypassing this problem. to fix this simply adjust the carb's fuel screw, located on the side of carb, a little at a time until runs smoothly.
