Echo pb 650 running poor after warming up

[roket77]

I ran my echo pb650 today and it ran fine for about 45 minutes then it would bog down for a second or two then run normal(this all happens while at full throttle),,,i think i took exhaust screen out so i eliminated that as a problem,,i loosened gas cap for a few minuts to see if it was faulty but thats not it,,,its driving me crazy,,any ideas? any would help,,thanks,,mark

Check your pick up hose in the tank and the filter that is on it. I have had the filter plug or the hose get stuck up off of the bottom and it acts like it is running out of fuel.

i dont know hat i did,,but it seemed to help,,i ran it for and hour straight a couple of times and it seemded to do the trick,,hopefully it doesnt happen again,,i think the hose ran up the side from being too long,,thanks for the tip

Check the fuel filter....pull the line off at the carb and suck on to see if you can easuly pull gas. Don't confuse the purge line.
