So I have a Craftsman riding mower, and the compression of the engine is more than the battery and starter is designed to handle. If you just stand on the key it will eventually turn over and start but not like it should. My Son has the same problem with a newer Husqvarna. What's the fix?

If you hook up a set of jumper cables or a battery booster pack to provide more electrical power , does it turn better and start easier?

Many larger engines have a compression relief valve for starting, if it's sticking that could be your problem. Good luck

I'll try that. with them making every thing cheaper and cheaper , undersized cables and smallest possible starter and cheap undersize battery would all lead to a mower that started fine when brand new but as anything took power from it it had to build up momentum to get rpm high enough to start

Thanks guys.....I'll try the battery charger. Before you do that , check the connections are clean , shiny and tight. You may not need a charger. It could be that simple.

definitely clean your battery connections also if they look at all corroded that can be a definite cause of loss and is the lowest cost thing to do cleaning your own.
also I have't not gotten a battery on the 3 year warranty in a while 2 year 10-11 months and the batteries have been starting to give me issues , thing is to recognize it right away and get it in before the date on the receipt.
an easy test is set a timer for 10 minutes turn on your head lights if your vehicle won't start after your lights have been on 10 minutes go have the battery tested before you are out of warranty.
the smaller lawn tractor batteries you lucky to get 2 seasons from them the battery maintainers do help.

If they're 2 cylinder , get your valves adjusted . I had same problem with a 23 horse , worked like a charm after my small engine repair buddy adjusted them . I can verify ... this is critical. B&S V twin. There is a centrifugal compression release built into the camshaft. It barely bumps a valve open to ease the load on the system when starting. Also, they had a big problem with a lot of the cams. There was no recall, but they wore a lobe off quite quickly. There was a new # for the replacement cam. The slightest lobe wear, or even a very minor maladjustment of the valves requires much more power to turn it over against the compression. I bought several quite cheap (knowing what the problem was) little over $200 in parts and worked like a champ, just like when bought new. Valve adjustment is most critical .... and of course the condition of the cam. 18 HP, IIRC Guy took it to a shop who bought and charged him for a new bat., then new solenoid, then new starter, then .... gave up and gave it to me. New cam and 1 new tappet .... been running fine for 4 years now. (full synthetic oil, recommended by mfg)

^ This is all spot on. Let me add 1 thing to check. Most b&s starter gears are plastic. When they get some wear, the valleys of the gear teeth start to fill in, and it increases the force necessary to start. Have fixed multiple machines that started hard by putting a new gear on.
For by grace are you saved by faith, and not of yourselves, it is the gift of God.
