Hello everyone, I've searched around this forum many times in the past and have always found helpful information here from the members. After doing some research I've found a partial answer for my problem but I still need assistance.
I recently picked up a beautiful Super XL925 with tons of compression, advertised as needing some carb work. After checking fuel lines and overall condition, I threw some fresh fuel in it and got it to fire and run after 7 pulls or so. The saw was not happy idling, as it would want to die, so I made my adjustment to the L screw and got it to stay generally happy. When making my H screw adjustments, I could get the saw to 4 stroke but it would then want to die a couple seconds after releasing the throttle from WOT, eventually I got it where it would bog down for a second or 2 after WOT and then resume normal idle speed. I tried balancing my adjustments but never found a happy medium for everything. Later on I pulled the carb and checked the condition of everything, all gaskets and the diaphragm were in great shape, metering lever was set correctly, this leads me to my overall question. Would these governors, if they were faulty, make it so the saw dies or idle improperly after WOT? I'm assuming it would create an overly rich condition.
I noticed this carb has a governor for the high end needle, I'm understanding this can be bypassed with a bb or some tin cut to fit, however, I believe there is also a high end governor on the metering side of the carb. Please see the following pics, the carb kit I picked up has two welch plugs and I assume the smaller of the two is to replace the piece of brass with a hole in it on the metering side? (http://www.vepetersen.com/images/hspartslist.pdf, part no. 19) Wondering what experience you all have or what recommendations you can offer whether I should or should not bypass both or if i only need to bypass the governor on the side of the carb body. I heard on Arboristsite that someone put a bit of solder over the metering check valve hole of the brass piece on the metering side of the carb. I'll try and get pictures to upload as well, just want to get this ol girl running 100%. Thanks in advance!
