Contact your dealer ! but 32:1 sounds correct. 8 ounces of Lawnboy oil to two gallons of gasoline ....is 32:1, 8 ounces of oil to one gallon of fuel is 16:1 for the real old lawnboys,
When Toro bought out OMC,and started using Tecumseh mowers,the ratio changed in the late 80's or early nineties ! IIRC :o)
sounds like the needle valve is not seating some have a rubber tip on needle some have it in the seat but the fuel we now have rot the rubber never store with fuel if possible
4 cycle engines do not run on mixed fuel. Run on straight fuel. They have a spot to put oil in just like a lawn mover, and should be changed regularly. @ stroke engines run on mixed fuel.

Use a quality 2 cycle oil and mix it to the OIL supplier's recommended ratio. Today I use Stihl 2 cycle oil mixed @ 50:1 in a Pioneer that I purchased new in 1980. There are no gouges or scratches on the piston or cylinder and I have no carbon build up on the piston top. The manual (on stone tablets) recommends 24:1. Over the years the mixture has leaned from 24:1 (Saw Recommendation) to 28:1 (Lawn boy mower recommendation) to 32:1 (Oil provider 2gal premium/8oz chainsaw 2-cycle engine oil - used for many years) and finally the last 5 (±) years 50:1 (1gal premium/2.6oz Stihl 2-cycle engine oil)
Any fuel containing ethanol is not good with chainsaws. Mix what you expect to use within a few weeks. Anything over 1.5 months old use up in a 4 cycle engine. HTH

20:1 gas to oil is a good place to start. Some mowers thin down to 80:1. If you can tell me the model of the mower I can be more specific, but starting at 20:1 will assure you have adequate protection for the engine. If it's exhausting lots of oil smoke after it has warmed up; you can cut back a little each time until you have minor oil smoke.
at 20:1 you need to add 6.4 ounces of oil to one gallon of gas.
