Thanks Tyler and AVB, possibly a small misunderstanding, I was only offering you the old carburetor, the saw is running very well just a little nervous about the high speed mixture when tuning the carb by ear I could have it a little lean and cook the motor with a bit too much work. Time will tell, I have cut up everything I had on hand. At one stage I did have the fuel lines on the wrong way around, and I did take the muffler of and check for any obstructions just a bit embarrassed about how many hours I put into it to mention it earlier. I also neglected to mention that when I first got it running after adjusting the after market carb that it was blowing lots of fuel back out of the carburettor. That much that it was condencening on the handle and dripping onto the bench. I can only guess that the spline driver that I first set it up with was to big around on the outside and jammed on the housing when I was first setting it up making me think it was screwed all the way in. as it turned out the low speed jet was out about 4 turns. I have never come across that before and could not find any references to it being caused by poorly adjusted jets.
The low speed jet is out about 1 turn now. I never reset the high speed but it is probably about the same, it was running so I went from there and with the saw revving at about 3 quarters I turned it in about 3/4 turn until the saw slowed then back the other way until it slowed than set it in the middle which would be about half a turn from where it was on arrival so assuming it was set the same as the low originally it is out about 1 turn
What do you mean you have enough chain saws, I would not have thought that was possible. I have 5, this one, the wife bought me one on special from Aldi for $60, an electric Ryobi, a very old Homelite that AVB and others in this forum helped me get going, and if I actually want to cut anything a Husqvarna 460. The Husky is that powerful that it scares me but you will slice through 16" hardwood without breaking a sweat, next would be the old Homelite which would have originally came out with a 20" bar it has power to spare with the 16" bar on it and isn't bothered by 12" logs, but it is noisy, vibrates and the bar is in poor condition. The Ryobi is a little more powerful than the Aldi and a little more robust. Neither has the power to cut much more than 8". I have found in the past that the saws which have a plastic housing (Aldi) to hold the bar on tend to jam and push the chain off when you get into very light stuff like a hedge. The electric one is for the more patient arborist, but the safer option if you are up a tree and the battery goes flat on the reciprocating saw.
Again thank you both for your help
