I already broke one recoil starter assembly on my Astra Korea 3 kVA generator. I can start the generator, but with great effort. It takes about 6-8 pulls, and there's so much resistance that I can actually lift the generator partially off the floor by pulling the cord. Oil weight is 10w-40, With this problem the generator not start on battery, Please suggest the solution for this existing problem..

Depending the manufacture of the engine the actual replacement varies. You basically need to first remove recoil starter cover assembly. In the center in most recoil rope pulleys will be screw(bolt) that need to be removed. Pay close attention the assembly order or the parts; take picture if necessary. Once you things a part and old spring is removed. Be careful even broken springs can go flying and cause injuries. Carefully put the new spring in the correct direction. Re-assemble the rope pulley unit. To put tension on the spring you wind the pulley in the same direction as it would if you was pulling the rope out. Wind until it stops then unwind up to one turn depending where the rope enters the pulley and install the starter rope. After the starter rope is installed slow let the pulley take up rope slack. Then you re-install the starter cover assembly on the engine.

Note on some engine other components needs removing just to the starter cover off. I know of some Briggs engine that this is true as the carburetors has to come off first.

You may have to remove the recoil starter. Be careful, the spring, etc. may have disconnected from the recoil starter housing. There are probably 3 machine screws to remove to get the starter assembly off.
Then try the electric start.
Starter assemblies are a standard repair part.
Let me know if this helps.

Generic version of your starter is most likely available from small engine shop. Look for model and type of engine itself. Briggs stratton, honda, etc. model number if engine is usually on starter cover or stamped on block or tag attached. If the recoil part is riveted to housing you may need to either re-rivet or use screws to attach new rewind. Used parts are also available at small engine shops. Just take in the starter housing only for match-up. Good luck

I hope it helps.

I got one of these pieces of junk, and had same problem you described.

You will need to remove the end panel to get to the blower housing. You will have to thread the rope through the handle until you have enough slack to remove the rope from the handle. The end panel should now be free to remove entirely.

Find the 3 bolts that hold the blower housing on, and remove them. Once you get it off, make sure that the rope has a knot in it so it won't get retracted into the pulley recoil assembly. Take a screwdriver and push the rope back down into the pulley (that was my problem). Assembly is opposite of taking apart.

i'm sorry to tell you this, you have to take take the hole recoil apart.either the spring is broken or the dog that holes the spring is not engaged.to fix it you have to take it apart.restring the rope,make sure the dog is catching the spring,rotate the recoil rotor to tension the spring,retie the handle and reinstall the recoil as an assembly.hope this helps,let me know if you have any questions...........

I bought a replacement recoil starter for my 1850 at Pats small engine parts. The part number for a 3.5 B & S is 499706. If you look on the heat shield on the side of the motor there is the engine model and s/n. Hope this helps.

did you find a solution for replacement? thanks
