got an old weedeater that was doing the typical bog and stall on acceleration, so I started assing around with it. plug looked good, spark arrestor screen clean, so I went for the carb. learned what I could from the webs and carved up them little EPA plastic anti tamper gajiggers real nice. this is where the frustration began.
after much screw twisting and cursing it seems to be running and accelerating well, but I wonder if it's right, and if there is a more methodical way to do this in the future.
maybe some 2 stroke gurus on here?
-is the low speed screw always on the engine side and the high speed screw always on the air cleaner side, or is that just typical?
-is clockwise always leaner?
-how much effect does the low speed setting have on full throttle operation? seems like nothing to a lot depending on,, maybe ghosts?
-which of the goddamn things do you adjust first?? internet cannot decide. consensus seems to be low speed.
-what is happening under load? I feel like I needed to lean it out a bit (H clockwise) for good performance, but then under no load won't it be too lean?
-how do I know if it's too lean? everything said back off H 1/8 turn from max rpms, or find a middle ground between max rpms and obviously too rich. what I found was that 'max rpms' (to my ear) was almost 1/4 turn range with the leanest end of that range starting to miss pretty obviously.
-is there really a proper way of doing this or is the 3 screw fiddlefuck a time honoured tradition not to be trifled with?
