the black spots aren’t really to much of a concern to me. its the worms that look like small spikes. they do move around. if there is a few then I just pick them out. its when there is an abundance of them is my concern
thanks for the advice. I tore carb apart. starts right up and idles with choke open. any change in choke it dies out. sometimes it will throttle up in open choke. sometimes not. any suggestions on how to clean jet. and location on jet please? and thanks again
