Please post your engine model and type numbers.

What do you mean by new ignition? Are you refereing to a coil? Does the engine have points and condensor? Post the info and we can help.

2 things come to mind.

1) even though you put new points, did you clean them after installing? If not get 2 thin strips of clean lint free heavy paper stock. Wet one with crab cleaner and run through the points. Run the other through dry.

2) If you replaced the coil, I am assuming you replaced the stator plate also. If so you will need to set timing. Do you have a tecumseh dial indicator to do this?

If your coil is located underneath the flywheel, you do not need to adjust the gap between the magnets and the coil. One of the most common reasons for a no spark issue is contact between one of the wires where it connects to the points and a ground. Routing the condenser wire incorrectly can allow it to rub against the flywheel and ground out. Check the kill switch lead and make sure it's not grounded as well.

Same 7HP HSK70

Sorry to butt in, but couldn't figure out how to do a new post.
I've got a 7HP on a snow blower. The mice got in it so I put a new coil and carb on it. I've got it running pretty good, but it throws flames out the muffler like a dragster on a saturday night under the lights. I don't want to hurt the engine. I know that the top adjusment is for low idle and the bottom adjustment on the bowl is for the high idle, but would the screw on the side by the muffler have anything to do with it? I don't want to mess with it since it should have come already set. Do I have the coil st too close? I think I have it set to specs.

Again. I apologize for jumping in. Any help would be appreciated!

Thanks,
Bruce

Tecumseh no spark

I am also interested in your problem here. New to the forum and this place is right up my alley. I to have a no spark problem. Mine is a H70. The magnets came off the flywheel. I reglued them after marking the old glue area. They seem to line up nicely with the coil. I checked the wiring and crossed check with a running 5HP that I have, still no spark. Can we figure this out together.

I have never had any luck gluing the magnets back on either, I don't know for sure or if it even makes any difference, but perhaps the polarity on the magnets may be wrong.
