I have been working on a Husqvarna lawn mower this weekend and finally got it to start. It ran for about 5 seconds and stopped. Of course when I finally got it to start the pull cord along with the recoil spring broke. I can not find the part number to buy another to replace. My question is are all pull start and recoil springs the same for all Briggs and Stratton engines? I have a Husqvarna Crown Series 6.75 HP.

Some place on theml blower housing the engine there will be a area that will have model, type, code. We will need the number to assist you in looking up parts.

I found a number stamped in the sheet metal above the muffler, see number below

121682 0248 E1 024218 FA - it was pretty hard to read I hope this is right.

Thanks

Something is not right with your model number but I am guessing with a 121682-0243-e1 the starter pulley, spring combination is a part number 498144.

Pull rope should be a #4 rope which means 4 mm diameter, you will have to measure length that you need.

Who would carry this item (recoil spring and cord)? Would Lowes, Sears etc...?

No Sears and Lowes do not carry in store. Found it on line at sears.com

I found the recoil spring and pull cord at McHenry small engine parts in Frederick MD. I installed and all went well. I got the lawnmower to start but will not run for long. A little background - I have had the mower for a couple years and have never had it running until now. When performing the maintenance I have done up to this point a spring broke, I'm not sure what it is for, it attached to the choke linkage. What next? Thanks for the help up to this point.

Oil has been changed, new spark plug, need to get an oil filter and the bracket that holds it down. What is the spring for? This is the spring that attaches to the choke linkage - I think? Can this spring be the cause of the issue where the engine does not run for long?

I hope you bought an OEM spring. It is very important for this spring.

I don't have a spring. What is it called and what is its purpose? Is this why the lawn mower won't run for long?

Briggs and Stratton 121602-0221-B1 Parts Diagrams for Brake, Controls, Governor Spring, Ignition
Part number 209a or 211

I agree the spring that was there looked like 209A or 211, what is the difference? Do I need both?

I don't know what one or if you need two but for eight you get both.

One of the springs was way too small so I got the other one. I installed the spring, I may be installing wrong but it doesn't put any tension. I get the mower to start and it just doesn't want to run long. I can keep running if I spray starter fluid into card, which tells me either the spark is weak or the fuel is not getting there consistently. What do you all think? What next?

Clean the carb.

good description I will be cleaning the carb in the morning. I will let you know the outcome.

I cleaned the carburetor and it definitely needed it. A couple things to note, the bowl gasket is stretched and dried out, I will need another one. Noticed there is not a fuel filter, should there be one installed in line? One last thing the gasket that is between the carb and primer bulb needs replacing. Looks like Monday.

Update - got the carburetor straightened out and the mower starts up. Only problem is it runs for about 5 to 10 minutes, noticed 1 thing the primer bulb has a hole in it, is this normal?

No replace it.

I confirmed the primer bulb is supposed to have a hole in it. So I am back to the fact the mower still only runs for a limited amount of time. Is there a way to test the coil, the mower runs strong for a limited amount of time and then just stops. I assume that the carburetor is clear and doing what it is suppose to do. I am thinking the coil gets hot and the spark gets weak or non-existant or at the very best weak.

What is the limited amount of time?

15 to 20 minutes of cutting grass.

Is it possible that the gas tank is not venting properly (usually through the cap) and creating a vacuum and starving the engine of gas?

Had not thought of that, is there a way to check that other than taking the cap off and trying to start? I'll check later today and report.

Loosen the cap and mow. or whem it starts to die loosen cap and see if it fixes it

Loosening the gas cap had the same result, except now it starts and will only continue to run if I continue to push the primer.

Check your fuel lines for dirt or kinks. Sounds like a kinked or clogged line. Also re check needle valve and see if its moving when the float goes down.
