Default My 86 is dead......

ok guys....as of recently my 86 died on me...im sick of working on it and going 3 steps forward and 6 back.

I recently put new points on it (about 2 weeks ago) and after fooling around with them to get it to start she ran great but wouldnt go over half throttle, so i had a brand new carb and stuck it on there and she reved all the way up no problem but spitted WOT. Well today i went to go cut a tree in the yard and hauling a small trailer behind it she didnt want to pull a hill at all. Im starting to wonder whats going on now...

1. replaced the points again
2. replaced the S/G (better safe than sorry)
3. replaced the carb.
4. replaced the battery (3 times now)

Ive adjusted the points alot and back fires hard threw the carb but only when you pull the choke on or have it on idle.

Reset the carb back to stock settings so i can elimate problems there.

charged the battery so i know its hot and ready

Now its in the shop tore down to just a block in the frame (kind of), i pulled the head off to see if it the exhaust valve is opening with the ACR (its not) so i adjusted the exhaust valve to compensate for that since the PO had it like that and now its worse....

Any ideas? heard it might be the mechanical timing but i doubt it. Could the ACR be shot? If the ACR is shot will another cam from another motor work or no? I believe my motor is a 14HP by the bore and stroke (have had it down before for oil pan issues) i have a 12HP that has a broke piston but cam is good...I really need help with this guys...my 86 is the work horse here and NEED her by spring cuz i have alot of jobs lined up....really dont want to use my 1650 for plowing and blading since i mow with it and hate pulling the mule drive and deck out from under it.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
