17.5 Briggs & Stratton Starting Problem

I have a Poulan Riding mower with a 17.5 HP Brigss & Stratton engine. I recently replaced starter and battery, now it will barely turn over? I have checked the connections, and all is ok with them? Could it be the solenoid?

Thanks.

Napa Auto Parts got the starter for me and I charged the battery when I bought it. Is there a chance something shorted out? I agree it doesn't act like a charged battery.....

Check the valve lash on your engine. Too much clearance will render the compression release inoperative, this will result in higher engine compression that the starter motor may not be able to overcome.

Also make sure that the carburetor is not flooding or leaking fuel into the cylinder and causing a hydraulic lock.

Take out the spark plug and see if it will spin over ok with the electric starter. Be sure to ground the spark plug lead wire so if any gas comes out when you crank the engine over it will not ignite and start a fire.

I removed the spark plug and it would turn over. But when I installed the plug and tried again the starter begin to smoke? So is there too much compression? How do I check the valve lash,etc...? Thanks for your help!

Maybe you should look at how the starter motor is connecting to the flywheel, maybe it's binding up. Did the mower run before the starter change out?

to check the valve lash you have to remove the valve cover. Then with the engine at top dead center, check the clearance between the rocker arm and the valve stem. (I am making an assumption that your engine is an OHV). For the proper valve lash settings you will need your model number and you can look them up on the Briggs website, or post your model and type number and I can get them for you.

Too much compression can cause a starter to smoke, also insufficient current can cause a similar problem. Make sure your cables are good, and that all connections are clean and tight.

Up and running!!

I want to thank everyone here for all of your help! I ordered a new starter from Briggs and Stratton and found out as soon as I took it out of the box...the other starter was evidently an after market starter!! It was so flimsy
and cheap compared to this new one!! So again.....Thanks Guys!!!!!!!!
