I have recently changed my contact point and condenser to my snowblower with Tecumseh Engine. After putting it back, no sparks. I changed also the spark plug and tried the other also, but still no spark. Not sure why no spark and if there is anything to ground. Someone says grounding and I don't know how or maybe some other issues? Please help. Thanks

Did you put the crankshaft high side against the points before you set the gap ?
If so could be coil / amuture.
Luck

Thanks DG. I'm new to this. Which one is the crankshaft? Is there any diagram that I can easily follow? Thks again

Do you have the model and type of the engine ?

Model is Tecumseh Engine HS50-67159B / Ignition Coil +30545
This is looks like an older model.
I appreciate your assistance. Thanks

Do you think I have to change the ignition coil?

If you have the gap set right at the points and you have no fire , then yes . But verify no fire ,
Spray a little carb cleaner in the carb throat , if it tries to start then clean carb,

Thanks. When you say carb is it the carburator?

Yes sir sorry about that ,
