Boy... Gravity's a *****.. Oil leaking past your valves will cause it.. not nec. air.. :goodl:
Check your model number. The stickys manuals section has some, Sonnys bolens has others. I have a hard time finding Bolens snowblower manuals, nothing that matches mine (model and serial are worn off)iwhere could i get a printout of an owners manual for a tube frame 38" round-back snowblower?
