Take the points cover off and try drying the points. I've had the points get wet even with a good gasket and grommet. A few shots with a blow gun and it fires right up.

 

Thank you.

Where's the points cover on these guys?  I was figuring I was going to have to pull the flywheel to access them.

I think I have downloaded every manual for the M8 - I guess they aren't going to read themselves.

Yay!  No points!

I think I'll be going through this.

@Pete D You beat me to it! I was just going to say I didn't think the Magnums had points.

Since I touched wiring, too, I'm going to completely replace the wire I re-spliced.

I'm uncertain why a non-waterproof 30 amp fuse was installed in the solenoid control feed, but it's coming back out.  (Just an additional point of failure to worry about.)

I'm going through possibly problems, and I'm concerned about a possible high-draw starter.  All grounds & connections have been cleaned to bare metal & protected with dielectric grease.  I did not pull the starter bolts and clean the starter mounting surfaces, however.

I guess I could remove the starter back cover to blow it out & check the brushes just to be safe.

Cleaned up the C81 sluggish starter and got it working good. I did have to put a .010 shim under the front bolt. Brushes were good. 

Used a drill to turn the armature and cleaned the commutator with a stone.

Looks nice.

Hoping you made sure to cut a bit of relief into the phenolic separating the commutator contacts and used compressed air to thoroughly remove any grinding/cleaning residue.

I replaced the starter solenoid.  The wiring diagram shows an optional fuse that was in line with the solenoid, so I installed a waterproof fuse and replaced the previous wiring. When I looked, there was some sloppy electrical tape which I unwrapped and found the wire had been burnt and most of these strands were broken. I cut back beyond the damage and ran the new wire. Everything should be waterproof now, and the engine cranks. 

I have spark now, but it doesn't start. I used clear nail polish around the Welch plugs, and I'm afraid it may have gotten past them and blocked the air passages. Major DUH moment. I'm quite angry with myself.  I have a ton of incredibly small drills so I will clean them out and try again. Hopefully, my local small engine shop sells Welch plugs.

The other possibility is the fuel pump. I don't smell gas when I crank, even with the choke on, so after I'm sure that the carb is attached tightly and getting vacuum, I may reach out for assistance with these old fuel pumps. I know nothing about them.

I have some. Tell me what size.  I'll send a couple. 

They're aluminuminuminuminum. 

 

NOT steel.  

 

I get em from a place called Rick's Carbs I think??

 @Pullstart  and @wallfish have both showed me a neat trick. Mebbe @Stepney too.  

 

With the carb air cleaner base off so your hand can sit flat on the carb front, start cranking the engine. 

Very quickly use your hand to completely cover the whole carb front for a half second. 

For some reason this often causes the engine to start.  Super vacuum??

I'll start with the local shop simply because I don't know what size.  I'll bring the carb and let them match them.

Thank you.

Yep, but it's a long reach!  I'll ask the Mrs to help.

But I don't like the nuts sticking out on the outside.   

And it maximizes aerodynamic efficiency when traveling at high speeds... better fuel economy... very green... :handgestures-thumbupright:

snapped the top off a big pine tree in my side yard, taking some branches of the maple tree next to it on the way down.

:scared-eek:                  Glad it missed the camper and building.

It was close! I was standing on the front porch when it happened. It was LOUD! Sounded to me like something hit the roof of the house. I ran through the side yard to go in the back door & didn't even see it till later, it was raining so hard. Lol. Was quite relieved that nothing hit the house. :greetings-clapyellow:

Run outside in pouring rain. Check

Run outside in pouring rain during high wind event near trees. Check

Quite relieved nothing landed on YOU!

Broke out the pressurized (canister) sandblaster today, finished blasting the weight box for the '73, and got a coat of primer on that and other related parts.

Hopefully I'll get the red on tomorrow.  Low end paint job; Rustoleum and a roller.  Maybe I'll try to learn how to use a sprayer one of these days.

 

I need to get an air feed for the sandblaster headgear and some gloves that won't fill up with media. 

(I'm going to try to modify an old CPAP machine to blow air into the hood.)

I bought some stick on reflectors from Harbor Freight for the 308. The original ones on it are chipped pretty deeply. I'll drill out the old rivets and stick them on tomorrow.

Lung transplants can be done but why take the chance?   Filtration is the key here, not intending to rain on your parade but don't think an old CPAP will push enough air through a good filter.
