Hi MM,
Which motor are we talking about a PT or a F/C. These carbs are very simple what kills me with them is the primer caps and float needles. No point in going to the mower shop they will probably only have plastic needles anyway. Only way I can get them to work properly is by doing a full carby mod, cutting the cam to get rid of the lumps Victa put on the cam so the cable has problems getting the lifter to climb over the lumps. There is a lot of info on how to modify the carb I can look it up if you want me to
Lot of reading but here it is. One thing I don't think is in here is that I now file the throat of the carby where the cable enters the body, the reason being is because the cam is lifted higher because of the washers under it and the body needs to be filed to prevent bending the cable when you are clipping it into place. I might put a pic on the topic to show what I mean
