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.
