Tecumsh simply shuts off under a heavy load... lazy snowblower syndrome! Original Message Feb 23, 2014 6:13 pm
Old Ariens with a HSK70 engine (original was H70), starts right up and throws fine with the throttle wide open.... until it gets to work hard then it quickly just dies.
I release the belt tension, can start it right up again, and ease the belt into position while it clears it's load. Then it's business as usual until the next big load is encountered and it dies.
What could be going on? It's always been easy to start by hand and there's Stabil in the gas.
My assumption is that it needs to run richer, but since it starts so readily hesitate to change the needle setting.

to test the carb high speed to see if it's rich enough all he has to do is start it up stone cold and observe how it acts. i've set my 8 hp tecumseh up to start with the choke full on, throttle full high speed,prime the bulb 2 to 3 times and pull the cord. once the engine starts almost immediately (within 2 to 3 seconds) i can take the choke all the way off. how rich you set the high speed needle will determine how much choke the engine needs to stay running from an initial stone cold start. the leaner the high speed jet the longer the engine needs the choke when started cold to stay running. by having it a little rich it will start better in extreme cold, there will be less fussing with it when it starts and it will run cooler .
