I have a older (1997) Husqvqrna 22L line trimmer that I have rebuilt. I replaced the piston assembly (piston,rings,wrist pin and bearing). I also replaced the carbuetor with a new one. I can't get it to run!! The limiter caps have been removed from the jets, and I have misplaced them. I can get it to start and by playing with the choke I can keep it running. If I release the choke it revs up, then stalls out as if it is not getting gas or been choked. For initial set up, where should the jets be set? I started at 1-1/4 turns out on both the high and low, but I got nowhere! Should I back the "T" screw all the way off? Thanks for your help!
