Murray model 20213B push mower hard starting

[SIZE=3]Hello, I have a Murray model # 20213B with the Tecumseh engine. I have a starting problem, it would take 50-75 pulls before it would attempt to kick. I just rebuilt the carb and this thing still will not start cold. I will pull it for 50-75 times, it won't even kick. Pulling the cord for 50-75 pulls will not flood it, though, and it will eventually start. I think the primer is working, without the air box on, when I push the primer, I see some fuel come up out of the tube in the throttle body assembly. Spraying some carb cleaner directly in the throttle area wouldn't make it kick, either. There is spark, because once it starts, it will run all day. Also, once it has run, it will restart with 1 pull every time. Once it cools off, it will not start. Thanks for any advice[/SIZE]

How old is the mower/engine? Have you checked the compression?

Hello, it is from 1995, and I did not check compression. I thought of a burnt valve, but it runs too smoothly once started to be that.

You might not be getting good compression, making it hard to start, but once it gets warmed up things might expand & seal better making hot restarts easier. Plus, a hot engine generally starts easier anyhow. Hopefully Cheese will find this thread in a bit. He'll probably know what's going on, what parts you need and what color socks you should wear when making the repair.

Check your flywheel brake cable:
Clamp the deadman bar down then follow the cable to the engine, see if you can push it a bit more then try it.

Or when cold, check for spark. Or disconnect the kill wire from the coil and try it.

I agree with the above suggestions so far. Check the cable operation, then compression. When you try to start it, does it ever pop or try to start as in does it even make a hint that something is happening? Does it sometimes kick back when you pull it?

Thanks for the replies. Cheese- No, it doesn't even try to kick or pop until you pull it a whole bunch of times. It does not kick back when trying to start it, it pulls smoothly.
