So dads d21 we’ve been working over last few years and finally got it out and running it some,But it is smoking some. Heavier under more throttle. Not oil smoke though. Smells like fuel maybe. Could it be timing off a little. We bought this tractor “with motor built already”. Had a time ever getting it to crank first time until we figure out it was 180 on timing marks. So it’s hard to use timing marks.
Also it will pop a little out of exhaust some times if you rev it up quickly.
Also we had injection pump built by a local shop. Could it just be timing still a little off causing the fuel smoke?

D-21 engine injection pump (if that's what it is) shall be timed at 34 degrees BTDC. What are you timed at ??   If you think a D-21 is smoke free out the exhaust pipe, they are NOT. Valve lash needs to be adjusted to .017" COLD on intake and exhaust valves.

Hmmm, wonder if the pump shop used the series 2 fuel setting?

Many shops don't understand how to assemble a DC pump properly, and therefore the timing mark ends up in the wrong spot. It will be difficult to time without taking the pump apart and correcting it.
