Tecumseh HS50 help

4792 Views 6 Replies 7 Participants Last post by  dodge trucker
I am working on a HS50 (5hp) Tecumseh on a MTD snowblower for a friend. It has been setting since last winter and when he went to get it ready for use this year it was leaking gas at the carb. I removed the cover and found it had a hole in the gas line. Replaced the line and thought all was fine. Then found out it had no spark. Points and condenser (inside flywheel) later and I had spark. Then had to remove and clean carb. (Found out he had let it set outside in the weather all summer.) I have gotten the engine to run, but the problem is it will only idle, if you try to advance the throttle it wants to die. It will only start at idle and will run about 1 minute then die. What am I doing wrong or what have I missed.

Make sure there is no water left in the fuel tank as well. Techys are very tempermental if any excessive moisture is present.
