I have one of these with a Walbro carburettor. I used it once about 5 years ago. Everything is like new. I am now trying to use it again. It has different ideas. It did not want to run, and now won't run properly. I have given it a new plug, new fuel with Stihl 2 stroke oil, dismantled the carburettor (all clean as a whistle), ensured the vent valve in the fuel cap is letting air in (it wasn't) and find it runs just as well on half choke as no choke, and I simply cannot get full revs. I have improved it a little by moving the 2 spring loaaded plastic screw heads (one white, one black) but only marginal improvement. I have them both fullly out at present (but they are only adjustable about half a turn. What else can/should I do?
(PS Bruce, you look like a saint from what I have read, and thanks for the welcome)
