Snapper line trimmer 31SNG

I've been fighting with this trimmer for the past 2 months and I think that the problem is carb related, but I don't know how to make the final adjustments. What happens is that I can get it started and it will run for a few minutes, but when it is placed under even a moderately heavy load it will bog down and quit. It may restart a few times, but eventually it will not start at all unless I let it sit for a few minutes. I have replaced the bulb and both fuel lines, but I'm not at all sure of the the settings on the 3 screws which control fuel/air flow to the carb.

Does anyone have an idea how to relieve my frustrations? Last year I put it in the local shop for a tune-up, but it's never run right since. I probably would have been better off buying a new trimmer, but my stubborness dictates that I try to solve this problem myself!

Thanks for your help.

You might check the spark arrestor screen and or exhaust ports. A restricted exhaust can cause a similar problem.
