What is the oil to gas mixture ratio on 1995 Toro Snowblower model 38170

Try a short burst of starter fluid into the carburetor and promptly pull starter. If it runs for a couple seconds and quits then the carburetor is not delivering fuel.

If it doesnt run on starter fluid then either flooded, insufficient spark, or poor compression / crankcase leak.

Hi Jerome:
Shouldn't be too bad.
You could disconnect the fuel line at the carb and drain the tank.
Drain and flush the carb. Reconnect the fuel line and fill with fresh gas.
If it won't start, pull the spark plug and clean/dry it with a propane torch, or replace it.
Odds are it will be fine.
Cheers.

The gas oil ratio on all Poulan models is 40:1.
First, I recommend a synthetic oil mix if you can find it and also recommend running a 93 octane gasoline.
Second, I would mix no more than 1 gallon at a time, unless you are doing a lot of cutting.
Gas/Oil mixtures do not last that long. I don't give them more than a month, and generally try to run any mixture within 2 weeks.
Think about it, gas cam gum up on it's own when let sitting for too long. Imagine what it can do with oil mixed in it.
Good luck with your saw, and be careful when cutting.

The manual can be downloaded from this webpage, you need the serial number to do this.

Two stroke engines usually use a 1:50 oil/gas mixture but it would be wise to consult the manual.

Hope this helps !

Is your rubber seat possibly sideways?
Also take the float back out and see if has fuel in it.
sometimes the foat has gas in it and it drops down and the gas keeps coming in the carb.

Your gas to oil ratio is 32 to 1. Should cut down on smoke. replace sparkplug at same time.
