How to tell you have spark on a MF8 Tescumseh HM80 model 155019? Took off the fly wheel and it look strange to me. Thought I would see points! And what parts would should be looking at. Electric start.

Thanks

The hm80 on my MF8 has points. That spec no. should have points. They are under the flywheel behind an alluminum cover . You could have a replacement engine on there or it could have been modded to electronic ignition. A photo would help.

If you can't tell on spark, get one of these. http://www.harborfre...cker-69014.html

If it glows dim & constant or nothing at all, flywheel is coming off to fix the problem (assuming no short out problem on the switch)

MF8 Found the points cleaned up everything up. Have spark, only orange color. So order patrs, points, conenser, and coil. Knew on here I'll try to show pictures when I learn how. Enjoy reading the Forums. Really helpful. This has not ran over 30 years. Seems parts for this MF8 are higher? MF 8 H serial no. 1590503915 , engine HM80 serial no. 155019 2297p
Mover MF 710 serial no. 1590859 843 the 8 maybe a 6. how do you get to say Thanks! Also have a case 446 16 hp twin.

Glad to hear you are making progress. It's a big job to get those flywheels off sometimes. I much prefer working on the Kohler K's with the points in their own compartment on the outside of the engine!

I agree with you Brian. Putting the points behind the flywheel is not the brightest idea, especially with them being a service item. :confuse: Glad your getting it it whipped Leroy. :thumbs:

Glad you got it going! I'm no Tecumseh guru, but it sounds like you have it going your way!

When I got my 8 it had been sitting for 5 years. Had a stuck valve which i got working again with some penetrating oil. Cleaned the carb and away it went. Those Tec. carbs have a bad reputation but can be rebuilt if they are not too far gone.

Good to hear you brought it back to life!

If it's sat that long, running a lite mixed gas for a tank or two would be good for it.
