R5 runs but stalls

I also had a problem with stalling with a Zenith K5, or having to baby it up to any speed. All kinds of suggestions but I read the manual and opened the high speed jet another 1/2 turn and now it runs OK. I am going to try it a little farther open, but it made a huge difference. Grant. Try the cheap and simple things first.

make sure nothing is in the tank but fuel....i mean nothing...

-once found a bumblebee in a gas tank...dried...hard...was plugging off tank outlet..

Neighbor had one here always afraid to use it even back in the 60's, cause it burned 5 gallons/per hour to get any work done. Takes a good sized fuel line to run that much fuel,without any blockages.

I'll check the tank and line again - that would be too easy but maybe so. And yes R5 is known for its appetite for gas.

-what about fuel filter? must be something before carb?

Just a sediment bowl - it's clear. I pulled the fuel line from the carb and cranked the engine - the pump is pushing fuel. But if the lines or tank are restricted by debris that might be enough to retard flow to carb. I'll check it out tomorrow.
