I just bought a used ariens snowblower yesterday...The guy told me that it was running fine last year and that he used it once this year but that he was not able to start it twice. the motor was turning free by hands so i bought it thinking that it was a carb broblem, I cleaned it completely,replace the needle, verifyed the spark plug to see if it was doing spark and it did...But still wont start... the gas arrive without problem and the spark is there to but it does'nt start. Any suggestions??? (maybe a timing problem ???) Thanks.

for anything you want to know about thig engine go to www.smallenginesuppliers.com. they have a complete service manual for all tecumseh horizontal shaft that you can download.. does sound like timing to me, if your engine is a h60 or h70 series, find top dead centre of piston, then turn crank back counter clockwise 7 degrees(looking fron ignition end of engine )remove the wires off the points, loosen the two bolts holding the breaker plate, connect a ohmmeter. one lead to the motor frame the other to the poihts(where you previosly remover wires) slowly move the breaker plate until the meter drops to 0 ohms and tighten the breaker plate bolts. this shoud get you very close ps. if your motor is a h70 orh60 series, can you tell me where the governor spring attaches to carb? hope is helps good luck colin

Ok so here's the thing...I just removed the carb again to clean it completely just in case that I forgot to clean something before...I will re-install it tomorrow. The fuel is getting to the carb without problem, the spark plug is doing spark but it still not start. Yesterday I verified if the magnet that is glued on the flywheel was there and everything look nice, the spark plug is getting wet if I try to start the snowblower....I already open the head of the motor and both cylinder and piston are nice...The valves are dirty but working fine so I cleaned the the best I could.Like I said I will re-install the carb tomorrow and give it a last shot, if it's still won't start I will bring it to a professional... If you think about something else don't hesitate... Thanks. Just wanted to add that you can't really tell by "looking" at the piston/cylinders. You need to check compression with a tester. They aren't too expensive, or maybe you could rent one from an auto parts store. If the compression is low, it might be a bad head gasket also.

I'm in agreement with newjerseybt "Make sure flywheel key is not broken which will knock your timing way off." Dave Wilson
