When mine does that I go back and reprime repeating the process. It seems the gas does not feed up fully with the initial priming effort. Once it starts I move the choke lever quickly on way or the other to see if I can keep it running until it gets warmed up. Sometimes I have to adjust the choke setting even after it has run for a while.
with trimmers , there is a shaft or as in a bent shaft a cable that has square drives and ends
these can become oval or break off if continual heavy loads are applied to the cutter head
next there is a centrifugal clutch at the top of the shaft and if continually used in heavy work that clutch will wear out and not grip sufficiently to drive the shaft
most cutter heads do not suffer problems other than to get loose and work down the tube thereby allowing the square drives to part
The Craftsman part number 66054 corresponds to a link arm, but without specific details or access to Craftsman's database, it's challenging to provide the exact length of this part. To find the precise length of the link arm with part number 66054, I recommend checking the product description or reaching out to Craftsman directly through their customer support or website. They should be able to provide you with the accurate information you need.
Hi Joe
Still having trouble with that old mower! I thought you fixed it? You stated
the reason it was turning over and lock up the mower had the wrong starter on it the Starter Motor Drive Bendix had 16 teeth and the mower needed a Starter with 14 teeth so I changed the Starter out. That's what I did.
I reckon you are using batteries that are wearing out and don't have the required amps. Jump start the mower using your Santa Fe with the engine running. Or take the batteries to an Interstate Battery shop and ask them to test them. That is free, but they can also pulse charge them to desulphate the plates. There is a small charge for that and they keep the battery for 24 hours.
Other things you can try.
Remove the starter and connect it direct to the battery. See if it spins freely?
Turn the engine over by hand to see if there is stiffness. Then do it with the plugs out.

Hello Joe
How old is the battery? Battery life in mowers is bad because they usually aren't well looked after in the winter, 6 months use and 6 months neglect.
Also fuel is often left in the tank and in the carb which goes funky.
Do you have a compression tester?
