I have a snowblower of Canadiana 825 Series 606 787 (78).
The engine is a Noma 8hp (Tecmseh).
The engine runs with only 1 / 3 throttle idle. If I give more gas (> 1 / 3) he dies.
(with or without choke)
I have already:
Camshaft for rechecking
Check-valve
Disassemble the carburetor and set-
Gasoline replaced

Can you help me?
Thank you
