The new brake levers I purchased from a scooter supply house are so stiff the brakes would not return and disengage the brake switch. I installed return springs on the arm of my disc brake calipers and the problem was solved. Maybe it would help if I lube the cables and the levers to minimize resistence. Now I have a LED brake light activated by both brake levers.

Keeping cables lubed is always a good idea. Even light surface rust on the surface of the cable will make it drag and in damp weather that can happen very quickly.

The first thing I do with any new cable is drizzle light oil into the sheath opening as I work the cable up and down. I put in a good amount, do it for a minute or so. Then hang it vertical from the rafters overnight.

That one you won't have to worry about.

Something I used to do with motorcycle cables was use Plasticine to make a funnel on the end of the cable and then hang the cable up overnight with a good helping of 30 weight motor oil in the funnel. Despite living on a coastal island at the time with a lot of sea salt in the air I never had any problems with the cables on any of my bikes.

Good excuse to buy an upgrade... lol any suggestions?

Also could the leak at the plugs cause the 4 stroking?
The fuel is definitely coming from the carb. And I already check the float, it floats.
I had to put a repair insert in my 1956 Matchless G-80-S single 500 cc and was quite satisfied. I got it at Wholesale Tool. They are online too. It is a solid insert as opposed to a Helicoil. It come with a tap that screws into what is left of the original plug threads and digs the new thread behind the lead thread. The insert has a knurl at the top and a flaring tool to set it. The plug is used to insert the repair. It is pretty economical to buy.

I changed the oil and the oil breather on my Briggs 3 hp 4 stroke engine. I also change the pleated paper air filter as the breather was not functioning for a long time. The spring broken or stuck and the valve was more than normal opening and not moving closed at all.

The return tube to the air filter from the breather made a mess of the filter. I had no replacement pre-cleaner filter that is the foam thing in front of the paper filter, but washed it with dish wash soap and rinsed and dried it. I have another pre-cleaner and air filter on order along with some starter cord.

I also will change the recoil starter cord, but temporarily I just cut off the last foot that was frayed. It will not fray for the same reason it was. It was before that I had started the engine pulling the cord side ways to clear a cover I made to protect the carburetor and linkages. I drilled a hole and put a plastic electrical strain relief (with the clamp center removed) on the top of the cover for the cord to go though and it stops abrasion.

I only can pull the cord about 18 inches, but my engine is easy to start so it doesn't matter. I’m not sure I would want the cord to be able to extend much further from where it comes through the cover. That is since I can start the engine while sitting on the bike and my position to pull further would likely hurt my shoulder. Standing up and starting a lawn mower I can understand using a longer cord.

PS, the engine ran fine with the oil breather not working, but it had a bit of smoke out the exhaust and now I expect when I get a chance to test it I know it has to be cleaner!

A really good pull starter cord, better than factory cord, is 550 Paracord. You can get it from any Military surplus store.
The Walmart variety is junk, don't get it from there.

Not too exciting, but started marking up a bit of steel tube and flat-bar. Rear engine mount fab fun coming up.

I may have caused myself a headache, but what the heck --- I've got several months to sort it out if it's not right!

I've changed my exhaust, went to a lower number jet, changed to a "6" range NGK plug, and lowered the float level slightly. Will see what happens tomorrow afternoon. May be great. May not.

The workmanship on the inside of my CNSV3 carb seems to be really good.

I purchased what I believe to be the tank I need to complete my early 50's Hiawatha.
