I have a SkilSaw Model 1616 Chainsaw that I am trying to get back into running order.
After conducting a Carburetor rebuild, I was able to get it started, however; it idles way to high. Note that I checked the Trigger Idle Screw and it was backed off all the way.
Next, I set the High & Low idle screws at 1-1/4 (per Walbro instructions) from where it was before (High was previously set at 2-turns and Low was at 3/4 Turn). It started, however it was running at a very high idle.
Finally, I start adjusting the Low Idle and when I tried screwing it in…it just idled even higher…and when I turned it open…it started to idle down. Problem is…that I screwed it open almost 3 turns before it finally started to idle down. I also adjust the High Idle and had to Open it up more than a turn and a half before it started to somewhat cooperate.
I never did get it to idle properly (simply ran out of daylight).
Here is one factor: The Carburetor is a Walbro WA8. In the operators manual, it calls for 16:1 Fuel. The only fuel I had at mixed at the time was Stihl Synthetic 50:1. I am wondering if that had something to do with it?
Here is some things I question and my resolves:
#1. Could it be just to rich of fuel? I might mix up some Richer grade fuel and try that?
#2. Could it be a possible Air Leak? (My next step is going to be a Vac/PSI Test and see what I find)
#3. Could there be something messed up with the Carburetor? I noticed that it doesn’t have one of those “Dome-Shaped-Welsh Plugs”. I blew everything out and replaced it the parts from a Kit.
Thoughts?
