I have a redmax eb7001 blower that won't stay running at speeds above an idle. In fact i have to fully choke it to keep it idling.

I have checked the following: Air cleaner, gas filter, tore apart and cleaned carb, removed and checked exhaust port, muffler and sparkarrester.

Is it due to humidity/temps? No adjustment for jetting. Any tricks?

Thanks in advance

Sounds like a fuel problem or lack there of. If the carb is a Walbro style, Did you replace the pump reeds in the carb? These typically get hard and don't seal after a while. Also, the ports in 2-cycle carbs are very small. It doesn't take much to clog one up. (Smaller than a grain of sand.)

i did not replace any parts in the carb. But fuel does make sense. i will look for a rebuild kit.

FYI: I have a new Echo string trimmer and the ratio is rated 50:1. I tried running it a bit rich the other day by using some 40:1 and it ran like crap. About like you mentiond. I could get the rpm's up but I had to take it there REALLY slowly.

Double checking your mix might be a good idea berfore having to output cash.

u have to choke it too run right, then it is running lean. Either it is pulling air in somewhere it shouldn't or the fueling system is failing.

i would buy a new carb. sounds like you've already worked on it with no results. i cant tell you but i have torn apart and soaked some carbs several times and it still didn't fix tha carb problem. i would buy a new carb and it would. some carbs are just a pain in the a$$

excellent advice........

to follow up i changed out (with new parts) gas filter, vent assy tubes from tank and gas cap assy. ran better but not right. finally i gave in and swapped the carb with a new one and it runs like new.

i did take apart and clean and reassemble the carb (with no new parts). Is it worth the $12 in a rebuild kit to fix it up? (a new carb set me back $48) Can it be fiddle with as far as the jetting? any up grade to an adj carb?

Thanks for your help....i'm blowing my customers away again!
