I put the chain saw together as instructed. I added the oil and the premix of oil and gas. Followed the instructions including the choke and pulls. I pulled the spark plug to see if it was fouled. It wasn't. Just need to be sanded down a bit. I even thought it was flooded and pulled the cord with the trottle off. Not even a hint of starting up.
I bought a new dirtbike as a kid n same thing.it turned out ,it needed to be a synthedic oil in the mix.try seeing for spark to begin with by putting sparkplug in the wire n touching diode to the engine block while pulling the cord.thats a good starting point to diagnosing your problem.maybe try warming it up in the house then try starting it with no choke needed.the saws i ve used needed you to give it throttle after you pull,n no throttle with choke.

It's really dependent on the particular saw's requirements.
Old saws used to need a 25:1 fuel/oil ratio, and modern saws as little as 50:1. Somewhere in between these extremes is a safe bet. Use a little extra oil in the fuel for new saws in the "running-in" period or after a rebuild. If the spark plus fouls, then lean it off a little.
More important is to use good quality oil: name-brand products are usually safe, and usually recommend the appropriate ratio on the packaging.
Chain oil is another, different product that has a separate tank for lubing the chain, bar & sprocket. Usually at the front end of the saw, the tank requires refilling with chain & bar oil at the same time the premix tank is filled. It's usually a high-tack oil, with anti-throw properties for use on the high-speed chain. Name-brand products are recommended, with vegetable-based oils preferred to mineral-based for environmental pollution reasons.
I also have a BlueMax 45cc chainsaw that I could not start right out of the box. I got lucky a couple of times after many (20 or 30 pulls) but normally I just gave up. Many others online seem to be having this problem with this chainsaw.
It turns out the solution for me was that the starting instructions in the manual are not really complete, there is another step that aids in starting: it needs some throttle. The chainsaw does not like to start with power at idle. After setting the switch to on and setting the choke, as the manual says, before attempting to start, squeeze the throttle while pressing the side button to lock it. For me, this allowed it to FINALLY start with only a few pulls. I learned this when I ran across this video: How to start BlueMax Chainsaw 45CC
50:1 is the proper fuel to oil ratio. Make sure to premix the fuel and oil in it's own can using modern synthetic saw oil, and to shake the can thoroughly just before adding to the saw. NEVER try to adjust the chain when the engine is running! Turn the chain adjusting screw CW to tighten--be sure to loosen the cover mounting nuts so that the bar can move. When adjusting the chain, bring the chain up to the bottom of the bar, but not so tight that you can't move the chain by hand. Check bar oiling by running the tip near some cardboard at speed for several moments--it should throw off a thin line of oil. Go to: http://www.drystacked.com for 12 page article on theory and troubleshooting information for Walbro brand carburetors if you have trouble getting the saw to run correctly. Hope some of this helps!
Remove the spark plug, attach the wire and lay the shell on engine metal. Pull through--any spark? If nothing, take the machine back to the dealer for warranty service or exchange. You seem to have followed all the procedures necessary. Hope this helps!
Most saws built within the last 30 years or so can be run with 40:1 using modern synthetic saw oils. A number of late model units run 50:1. Make sure to premix the fuel and oil before adding to the saw. Hope this helps!
This should run well with 40:1 ratio using modern synthetic saw oils only. Always premix the fuel and oil in a can before adding to the saw, then agitate the saw to mix the old with the new. Hope this helps!
