Choke on this

In response to Ed’s implied question, and I paraphrase here, “What the hell have I been doing?”
I could drag out the usual answer of too many irons in too many fires, but this time I’m being vaguely logical about my target of being up and running for mid June. I asked myself “what need be done to ride?” The obvious answer of a choke sprang to mind. I did start and run the bike, but last time I tried it wanted to be choked… so off to the local Goodwill and $2.02 later I have a dog biscuit tin, soon to be a choke.
Here’s my progress so far….

Swimmer. Float. Sink.

Last weekend was the 38th CVMG Paris National Rally, Paris Ontario that is.

I brought down my 750 Commando and my MZ TS 150, I had hoped on selling the bike or at least generating some interest – alas the gods conspired against me and it wasn’t to be. The kind gentleman that helped me unload the MZ summed it up “If you can get it running I might buy it.”

I had brought the MZ bike down to Brantford on Friday night and took the trailer back to Toronto to load up the Norton. It’s not a long drive to Brantford from Toronto, and only 15 min from Brantford to Paris. So why, do you ask, am I hauling my Norton Commando? Simple answer is a family doesn’t fit on a bike – unless you’re in the 3rd world.

I arrive Saturday morning to discover that the key position labeled OFF is actually taillight, OFF is a click over – dead battery. No problem I think, this is a kick start – pull the plug – give it a kick and …. nope – nothing. It’s a 6v battery, didn’t have a spare or charger.

The bike was difficult to start in the fall – but runs fine when it does.

Back home I charged the battery and worked my leg until it was flooded. I decided that it shouldn’t flood after 3 kicks and pulled the carb off. Discovered that one side of the float was cracked and contained gas. I drained the float and let it sit in the sun for a few days to gas off – then soldered it up. There are some small stress fractures on both sides of the float, I tinned the leak and one of the bigger cracks on the other side. Tested it in a bowl of hot water, no bubbles.

Got it running last night, now I just need to fettle the carb to make it a less grumpy starter – could be old gas.

ps – if you are wondering about the title of the post, a float in German is a swimmer – I rather like the image of the float swimming in gas.

update: after posting this I went out to start the bike – started on third kick :-). I think the cases were just bogged down from too much kicking!

Carb Inspection

Want to get bike running – pulled carb apart to see what condition it is in. My plan is to replace cables, fluids and drop in a battery to see what happens.

Gave the Bing 32 a thorough cleaning and tear down. Looks like the mileage is accurate as there is very little wear. The slide and needle are in excellent shape.¬† Check out the brass float – or “swimmer” as it is called in German.
