Hi,
I bought an Toro mower with a Tecumseh engine at a sale and when I tried to start it the throttle butterfly was gummed up, so I cleaned the carb, and it starts and only run a few sec, so I know that it is not getting enough fuel in the bowl. However I cleaned it good and all the ports are open, but I have having a hard time setting the needle valve to get good flow once I put the bowl on. I have good flow at about the low float level when the bowl is off , but once I put the bowl on it is starving. I have adjust and rebuilt many carbs before and never had this issue. Scratching my head.
