I recently purchased a 450 series chainsaw and like it. However, I'm not able to get any grease through the grease gun and into the sprocket. Took it to the dealer whose service technician said that greasing the sprocket is not necessary. But, that if one does grease the sprocket once, then it should be greased during every gasoline tank refill.
So, my first question is whether greasing the sprocket is recommended and, if it isn't, why Husqvarna would include grease fittings in the chain bar and supply a grease gun and tube of grease?
The service technician had tried to pack grease into the gun better than I had packed it, but the gun still produced no grease. I'm remembering that my Jonsonred chainsaw had a similar gun, but it also had a cylinder that one could push on to pack the grease firmly before use.
The service technician then tried to sell me a non-Husqvarna grease gun, but I'd have to pay for it and also for a tube of grease to fill it. Frankly, this bothered out of principle, not the money. I've already paid for working parts when I purchased the product a month ago.
The service technician said the gun will work if the grease can REALLY be packed down. I asked what would happen after some use and some of the grease was out of the gun...same problem? He said no...the grease would be pulled toward the opening causing the gun to stay packed. I've left it with the service technician who will see if he can make the gun work. I'm doubting it.
So, as stated, (1) is it recommended/required to grease the sprocket and (2) how can I get a grease gun that works?
Thank you.

I am original owner of a 1984 Husky 61 saw and still use it often. My question is regarding gas/oil mix. I believe I remember the owners manual referencing 24:1, but the manual is long since lost. This is quite rich by today's standards, I get OK plug life and the dome of the piston is not carboned over. A couple of individuals have suggested backing down to 40:1, but I hesitate to change based on nearly 30 years of use without ever having the head off. Suggestions?
