Well here is the thing. I thought the same, however when I put bar oil in this location and then tried to start it up with fresh gas/oil, as I cranked on it it got harder, and harder to pull and turn the motor over, it got to the point that you could not pull the cord and turn it over, all most like it was locked up! I pulled the spark plug and then pulled the rope and bar oil/gas came out of the cylinder!!!I have been pulling no problem since. It was suggested that I put fresh straight gas in the reservoir and not put the spark plug back in, but continue to pull star it in order to try and flush the system out
FYI in case it wasn't noticed this is an auto oiler system. There is no plunger in the spot the used to have a manual pump that I have seen in pictures of other models of this style. Any ideas? do I have some type of crack somewhere that is allowing bar oil the get in the cylinder??A small engine mechanic/ instructor is trying to look up any info and I am doing the same so any help would be appreciated. THANKS
