Starter rope broke on husquavarna lawn mower.model 7021RD. KOHLER 4CYCLE ENGINE. NEEED INSTRUCTIONS FOR REPACING RECOIL SPRING

ANSWER : The part no. of the spring is 501763101 it comes in a plastic keeper so is very easy to fit, check the web for sellers.

ANSWER : Your starter/recoil unit has malfunctioned. Disassembly/inspection down to the point where you can get the recoil off will be required. Remove the engine cover screws. The recoil unit may be part of the cover or may be under it. You will easily be able to access it. Replacement parts for your mower are readily available.

ANSWER : If your rope broke, there was no reason to take the spring out. The rope can be replaced just by taking the rewind housing off, turning pulley to get rest of old rope out, wind the pulley (and spring) the direction the rope would be pull it when starting. Then , when it’s wound tight, back off to align the holes in pulley and cover. Hold it there, stick about an 8′ piece of rope from the outside through the pulley and tie a knot. Hold the rope and let the spring pull the rope back into the starter. an tie handle back. Take your housing, and spring to a shop. They can re-install the spring and put on a rope a heck of a lot cheaper that buying that whole assembly.

ANSWER : Sounds like either something is caught in the spool or the recoil spring is broken or the rewind spool is broken. You have to disassemble the unit to see. Do that and I think you will find the problem. When you do find it and need more help, please ask. Good luck…Lee

ANSWER : Hi hoho641…

Make sure you are getting spark at the spark plug, to do this:Remove your spark plug and check to be sure you are getting fire at the spark plug.You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting spark then:
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible. Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one.Make sure you are using fresh fuel.If the moweris over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.Be sure to mark the turns down on a piece of paper.That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
After you have the carburetor rebuilt that should solve you starting problem.

ANSWER : Pull your spark plug to ensure it isn’t a compression issue or even piston/rod damage. If it still doesn’t move, pull off your starter assembly and try to rotate the fly wheel by hand. If it turns, then your issue is in your recoil spring kit. You can replace the unit, or try to disassemble and reassemble.
