So i put the diaphragm carb back on my MTD's HS40 and got it to start with no leaks since I swapped the gasket and diaphragm. But now it'll only really stay running if i give it a lot of throttle. Ive played with the main and idle screws in and out and not much change. Its got a full tank of fresh gas, I popped a new spark plug on i bled the fuel line into a bucket and it comes out very strong. Im not sure where to go next with the trouble shooting. Any ideas?
