KAF620A ? there were a lot of changes on this model, so having the complete model code will help me pin point maybe your problem ?

Next I asked about serving ? what have you done to try to fix your issue ?

Cleaned carb and air intake

Thanks you have a KAF620A5, shortly after this year they changed the intake valves, you need to check the compression, it should be about 200 psi per cylinder, but before you do that pull the valve covers and make sure that the push rods are in place and didn't pop off any of the valves. They had a problem with the fuel gumming up on the intake valves and then the valve would stick (stay open) and then it would allow the push rod to fall out of place, what most dealers would do is check the compression and it would indicate OK but in all actuality the intake valve was not opening. If that is the case you will need to pull the head and replace the intake valves, lets check that and if that's it I can give you the updated part number. This sounds to me like what's going on ?

Also just putting the push rods back in place wont fix it, they will keep popping off.
