Don Livingston/rusty acres is the person who seams to be in the know about this .I know that he has a reconditioned dc intake and exhaust manifold for a dc tractor. what I am asking what does it take to recondition one other than the obvious trueing of the mating surfaces. I have heard a little talk about the ferials for the intake and exhaust .how do you know when the go bad? my dc ran really good 2 years ago then while moving snow heard a loud pop and after looking hard I found that I had lost a valve lock/keeper on number 4 exhaust . I let it sit in the shed till I found replacment parts. I have adjusted the valves a few times. but here a grueling in the intake as it is pulling air in will try to start but just pops of for a few revolutions before it dies. carb is getting gas. mag is sparking. just need some advice where I should look next as have fuel, have spark, and is in time per the book. the only thing I haven't tried is pull starting. also I know the compression is good

Thanks for any ideas in advance

you said it run good till you lost a valve keeper. then you adjusted the valves a few times. did you adjust each cyl. on TDC on the COMPRESSION stroke to .018? and what is the compression? a person needs actual setting spec's. diagnosing a problem . not questioning your work but need to eliminate stuff. have a hard time to believe its the manifold when it ran good before as you said. plus is the firing order correct...? 1342 clockwise. popping is caused by valves and timing.
