Well today I went and picked up a new head gasket and started to pull everything apart. All the head bolts came loose easily but 1 which broke there is 1/2in. of it sticking out but I can not get it out, I do not want to ez out it yet because there is enough meat to grab with vicescrips. I have been heating it and using penetrating oil but nothing yet. Any ideas?
On the other hand I found my reason for power loss a burnt and warped exhaust valve that is not seating,and 1/2 of the head gasket was leaking oil/gas mixture. At least the piston and cilinder looked good!

Any help on removing the broken stud would be great it is between the intake and exhaust ports.

THANKS

Keep soaking it with pb. tap it back down with a hammer, Becarful not to hit the deck at the top of the bore. If its pulled thight against the threads sometimes after a good whack thell come out with your fingers. just take your time and dont rush it.

Broken bolt removal: Find someone who's good with a wire-feed welder (if you aren't) and just glob some weld onto what's left of the bolt. Make sure the welder is turned up high enough to get decent penetration. The heat from the welder should loosen the bolt, and then you can put a vice-grip on the glob of weld and turn it out. I've removed one broken head bolt and 4 broken transaxle bolts this way.

Get a new exhaust valve and some valve grinding compound and you should be all set. Don't forget to check the head for flatness and correct it if it isn't flat.

With my snow plow(in raised position) on and my speed control lever in the fast position it will die out if on a soft surface like grass or a couple of inches of snow even at full throttel, I no my head gasket has a small leak but it i not enough for it to lack that much power. I no it is the hydro taking all the power that is why the biggest old style cub cadet with the standard trany only has a 12hp which is the 1200 quietline and the smallest motors they put in a hydro tractor is a 12hp-16hp. Thats why they made the cub. super and the newer modles because they have more hp. Thanks to all the members on OCC who replied.:biggrin2.gif:

If it quits at full throttle then there is something majorly wrong. My K241's can idle around in third gear with no problem.

Get that fixed and it will be much better

Just my 2 cents on this......... All my neighbors are convinced they need to have a huge motor to cut a 1/2 acre lot. I mean really, these idiots go spend $4k on a JD with a 21HP engine for a 42" deck. And to be honest, they don't cut any better or faster. Even all the "mowers" at the box stores seem to sell based on engine size. What a joke. My TRACTOR just does fine and my lawn always looks nicer than theirs. Maybe they're all insecure about something...............

Well I pulled out the exhaust valve and found a nice burnt, and bent exhaust valve. I still cant get the stud out I have a Lincoln 140 mig welder that I used to make a puddel weld on the top of the bolt but it still wont come out, now it looks like the tip of the stud is starting to twist but the rest of it in the block is not moving. I have been hitting it and pb ing it but still nothing.Any more suggestions??

Well at least I got 2 new valves for 35$ hopefully they will be in this week.
Ill try to post some pictures so you guys can get a better Idea of my problem.
Thanks
