Simplicity 1968 7HP 26" no spark.

New to the forum and 2 stage blowers. Had a single but girlfriend got it in the breakup.
Anyway, got this freebee from a good friend (yes he still is)no spark. Pulled off the heat/exhaust cover (wondered where that air intake was) and will unbolt the tank next. Can't figure out how to get the rear cover and pull start off, even with old diagram. Does not show that portion of machine.
Also, is it advisable to change Points/condenser to electronic while I have the flywheel visable?? Thanks in advance...Tom..

Hi Tom,
How exactly are you checking for spark? Have you tried a new plug? There are some things you can try before pulling things apart. Do you have any idea when this machine last ran? If it has sat for a while, it often becomes a project, not a repair. MH

Last run a few years ago, Daves wife bought him a new one and this has been sitting in the barn. Checked spark with "Clamp on meter", then with "in line spark light" and finally removed plug, "ethered" the hole, replaced plug and pulled,no start. Fresh gas (hitest) was the first thing, new plug came next. I'm assumeing the points are rusted. Thanks for the come back...Tom..

While I'm here, one other problem is "NO REVERSE". Not a big thing, but at 71, it might be nice to have it. Lever goes into High and low but when I pull up the lever doesn't go...Tom..

Having sat in the barn, there is a possibility that mice may have been chewing. They often build a nest inside the blower housing. The other possibility, aside from points, is a kill wire from the coil to the shutoff terminal that is grounding on the frame.
To remove the blower housing, remove the three bolts on top (head bolts) and a machine screw on lower right and left. The blower shroud and pull start mechanism will come off as a unit, exposing your flywheel. The flywheel is best pulled with a harmonic balance puller with screws that thread into the face of the flywheel. There is a nut/washer that has to be removed first. I use a belt to hold the flywheel to allow for enough torque to remove the nut. Wrap a belt around the perimeter of the flywheel and cinch the buckle tight to pull in a clockwise direction while you loosen the nut. I use a 16 inch breaker bar on a socket which works well. There are some good videos on the web that will walk you through flywheel removal techniques, which vary according to what tools you have on hand. Once you have removed the flywheel, you can get at the magneto/coil assembly which contains your points and condenser. MH

Thanks MH, I now have all the shrouds off and everything is open. No sign of micees. Lubed up carb linkage while looking around. I believe the "kill wire" is attached to the end of the carb throttle, sets when linkage is all the way forward, seems to be ok just greasy. I'll meter it tonight to see if it's working. If I upgrade to an "electronic Coil" (magnetron) can I leave the old coil and point attached or do I have to get at it under the fly wheel??

10PM--Copper wire at rear of coil is not grounded to the motor, so that circuit should work.

Sorry, can't answer that without seeing your current engine's setup. I don't convert any of my engines from breaker points to breakerless ignition. MH

Kats,
When I replaced the points in my B&S I left the points but the new "electronic Coil" (magnetron) was designed to fit in the same place as the old coil.

Thanks Tote,
Don't have the old coil out yet and as soon as I get the flywheel off I'll remove the cap/point setup.(need a puller). could have used the blower over the weekend, 19" since Thursday night.
