I'm working on a friends generator , history is as he tells it only 20 hours before he let it sit for a year . I removed and cleaned the fuel tank , disassembled the carb and cleaned it all out . Now I've found there is no cylinder compression at all . Is it possible the valves or rings are gummed up ? Should I do a leakdown test ? :confused:

My toro snowblower 5hp 1985 model wont star? all my switch are on I verify the spark plug and i have bleu sparks i unplug the sparks plug and i have compression, and i smell the sparksplug and i didnt smell gaz??? the gaz go to the carbourator,but i think that the gaz dont go to the engine.i will tray to put gat directly to the engine where the sparkplug is,and if the engine start mean that is the carburator,but how i fixed????? the carburator,the carburator dont have a primer!!( botton to press the gaz ) so i dont know how the gaz is push to the engine???? any help with my carburator!!!
