Problems with TD pump

[alex17young]

I'm planning on getting the turbo pump resealed or get the Giles magic sprinkled on it lol. I've just been putting it off for as long as possible. My local black hat diesel shop quoted me $500-600 for a NA resealed, who wants to do cheaper!? Anyways, I bolted up my ole reliable NA pump and it started and ran great. Lots of white smoke at start up at .097mm. Then it wouldnt hot start. So I just loosened it up and tugged the pump forward without the dial. It ran fine tonight it just doesn't hot start. Does the cold start lever have a shorter pull as the pump is retaded? Tomorrow I'll check my fuel lines from the tank. I'm stumped!

Right on, the perfect way to time it to your exact situation. By Ear. If it does not hot restart you may be looking at a compression issue, unfortunately. The cold start always has the exact same pull regardless of timing, but it is an exact added amount to the static timing you set it to. So say you set it to .95mm and the cold start adds .05mm, with it pulled out you have an idle timing of 1.00mm. If you set your static timing to .98mm, the cold start pulled will give you 1.03mm and so on etc. The .05mm is made up number, I cannot recall the actual amount of advance at this time.

I will be pm'ing you about the pump reseal .

I didn't want to mention compression but that very well could be it. I'd slap a gasket in there before I'd pay someone to do a compression test. Sounds good Jeremy.

I found the problem! The second compression ring on #3 and #4 were broke!
