Hi folks:I have owned and loved Cockshutts for over 20 years,but am new to your forum.Please bear with me while I bore you with my Cockshutt story.When I got into antique tractor pulling about 25 yrs. ago.I wanted something differant then the Farmalls and JDs that were common around here,so I bought my first Cockshutt,a 40D with the Buda diesel to compete against them.I fell in love with it the moment I heard that smooth Buda bark to life.Even though the 40 was worn out and beat up,I was impressed with how it held it's own against the other "freashened up" tractors.I knew it had a lot of potential the first time I pulled it since it had only been beaten by the best pulling tractor around,a souped up JD G owned by a friend.For the time being,I was happy with 2nd. place.A year later,I started searching for a parts tractor to help in the restoration of my 40.After a lot of "before internet"searching,I stumbled on a similar looking tractor in a junk yard.It had been used/abused it's whole in Canada and still had a big worn out snow blower on the rear and a old cab attached.It hadn't ran in many years,and had been painted all red but looked differant then my 40.After finding and scraping off the serial #,it turned out to be a 50D deluxe painted over.The 50 was pretty complete but beat up also,so after getting it running,I restored it and the 40D became the parts tractor.The next time the newly restored,still stock 50 came up against my friends souped up G,he went home with the 2nd place trophys and me with the 1st in both classes we competed in.Even against "enhanced" tractors,the 50 still finish'es in the top 3 and often 1st unless I screw up.The origional diesel has never been apart,nor has it's injectors/pump because it still dynos @62 pto hp after a little pump adjusting @ stock RPM's.It of course benifits from preheating below 50 deg.but starts up about the same as others I've read about on this forum.

  Now for my problem.When starting the engine  at operating temp after it has been shut down for a minute to a few minutes,it will crank over as it should but will not fire.If I stall the tractor and start it back up instantly,it will usually start,but will crank over more then it should as if not getting enough fuel.If it sits for aprox 10-15 minutes,it will then start as it should and run fine.The starter and battery are in good order and I've tried holding the throttle in differant positions.Anything above the off position offers the best chance of getting it started.If it doesn't start right up then I have to wait the 10-15 mins.The engine is not over heated,just normal temp.My old 40 diesel acted the same way when I was running it.When the pump pressure is backed off to achive about 55 hp,as I do if I'm going to use the tractor for something other then pulling,such as a tractor trip or parade,It starts much worse to the point where if it's shut down and then I imeadiatly try to start back up, it won't until it has sat for the 10-15 minute cool down.It acts like the fuel system has lost it's pressure.One time to help diagnouse the problem,I turned the pressure screw on the pump in to the point where the engine was past it's peak power(to rich)and it started up much better.Since this was an issue on both of my tractors,I'm thinking others may have the answer to my problem,maybe worn pump?I promise my future posts will be shorter
