Progress at last

Well, I finally got it far enough to fire off. Once I advanced the timing all the way on the pump it ran fairly smooth and had decent power but it still smokes pretty badly and burns your eyes in the shop with the exhaust. It should definitely burn cleaner. BUT, the second time I started it it developed a noise inside the open intake. Sounds like a compression leak near as I can tell. It fires on all cylinders and revs well but still smells of heavy fuel in the exhaust. Pump has a fresh rebuild but I found some of these style injectors use a narrow tip and some a wide tip. When I had extra injectors rebuilt I had wide tips done. This engine takes narrow so I had to use the old ones. I feel like I have 2 separate problems and I feel like the injectors are a little cruddy but I also feel like my timing is still a little on the low side. But that means cracking the timing cover and advancing the timing one tooth above factory marks. I'll get the injectors done before I do that. But the leak noise has me baffled. It didn't do this the first 5 minutes it ran and started about 5 seconds after my second start up. It IS coming from the intake and I can feel blow back into the intake but it does fire on all cylinders. Might not fire strong on all but it does run. All the valves still have good lash adjustment as I set that before start up. If I had trash in an intake valve it should change the lash. I'm considering pulling the tractor in reverse to see if I can pump any possible debris out then try to restart it. After that I'm afraid that the head will have to come off. I'm not looking forward to that at all. Never heard of one of these heads dropping a seat so I'm open for suggestions. Any takers on what I'll find??

After several years of collecting parts I finally made some progress on my D-15 Ind. After 4 parts engines, and 2 parts tractors the 15 gets it's chance in the shop. I have the loader for this tractor but no rear hoe so I'm installing later model I-600 rear lift and hydraulics for a more usefull tractor. Many thanks to all who have a hand in this project. Jamie Sigmon got tired of me bugging him and sold me the tractor, parts tractor from Niel Evans and lots of new parts from Sandy Lake Imp, and axle bushings from Tracy Martin. Still lots to do but it's coming together. Just lots of stuck and rusted linkage and valve body parts to clean and get freed up. Hope to here it run today with any luck.
