Try rebuilding the fuel pump first then the Carbs. Fuel pump kit is probably around ten bucks. Carb kits around 20 each. Fuel pump is easy, carbs will need a service manual to do the link and sync.

You might want to check to make sure the bulb on the fuel line is hard. Check for spark on all 3 cylinders. I had a similar problem and it turned out to be no spark on 2 of the cylinders and as soon as I applied any throttle it would die. Will it go into a fast idle in neutral and is the problem only when the motor is in gear?

Rule out the easy / cheap stuff first. I have seen a leaky fuel line cause that issue. Make sure that the bulb is staying hard when the engines runs. If it more than a few years old, replace it. Dont be in a hurry to tear apart your carbs.
