It should tell you the ratio on the saw.
Fairly simple. Fuel line up from tank.....underneath carb.....to right side of carb inlet fitting.
A Poulan Pro chainsaw may keep flooding out due to issues such as a clogged carburetor, a faulty fuel line, or a malfunctioning primer bulb. When these components are not operating correctly, excess fuel can enter the engine and cause flooding. Regular maintenance and cleaning of these parts can help prevent the chainsaw from flooding out.
50-1 ratio most definitely.
what is the fuel/oil mixture for a stil chainsaw model 1629
Try changing your fuel filter/lines. It could have had sucked something into the lines and cannot get any more fuel through.

50 to 1 on new ones. The old chain saws could have a ratio as much as 16 to 1.
Mix 1/2 pint (8oz.) for every gallon of gas. 16:1 Ratio
I recommend 40:1 with good quality oil.
From Poulan website: The fuel-oil mixture ratio for all Poulan two-cycle products is 40:1. You can obtain this ratio by mixing 3.2 oz. of oil with one gallon of regular gas. If you have other brands of equipment that require different fuel/oil ratios and you don't want to mix separate fuel cans, you should use the lowest numerical ratio. For example, if you have products requiring 40:1, 50:1, and 32:1 ratios you should use the 32:1 ratio for all products. This may cause slight smoke increase in the exhaust in the 40:1 and 50:1 products due to more oil in the fuel, but it won't damage either of the engines.
