wd -45 sputtering

Anonymous-0 · Jul 2, 2010

Hi all, during our 6 mile tractor parade yesterday my wd-45 ran good except she would miss , sputter , and black smoke occasionally. A couple of weeks ago she wouldn't start and I adjusted the bottom carb screw, but it was only an electrical problem Does anyone know how many turns from the bottom that srcew should be out ? I also disconnected the breather in fear that it is plugged? I know she is also due for points , since they are a little pitted.

Thanks in advance.

The main jet has a starting point of 1-1/4 to 1-1/2 turns out.
With the engine up to temperature and the throttle wide open turn the screw in "til the engine begins to slow and then out "til the engine runs smooth.
According to my D-17 manual, "an extra 1/8 to 1/4 turn will then give engine all the fuel required under load".
If you are using your tractor basically for shows
and parades, I would turn the needle out only to the minimum necessary to make it run smoothly.
In other words, adjust it on the lean side.
