The rusty old scooter.

You could also search the web for a manufacturer that makes the springs...here's one...

I?ve used TheSpringStore to get replacements for external fork springs on a Suzuki two stroke from the 1960s.
They also sell torsion springs & may have something that matches up close enough.

Thanks, you guys rock.
I went to bed last night thinking that there are thousands of springs used in thousands of applications....
Just a matter of finding one that will work. I got as far as looking up spring types, etc. I did wonder if fixing that one was even a legitimate thought.

And as much as ebay sucks at times, I'm occasionally shocked at what can be found. No spring, but a guy in Italy has full engine gasket kits, a set of NOS brake pads, a set of clutch fibers / steels and a lifetime plus supply (box of 30) of points. I'd buy it all if I could.

Lol, glad you have a direction then...I can relate to an extent. 30 some years ago I was trying to find 392 hemi parts for a motor I had {wish I still had it!} and those parts were impossible to find in any decent shape - or affordable if they were there. Then I tried my hand on kawi H-2s and low and behold, I had a knack for finding another piece that had a dismal following for certain parts as well....now one can find parts for either {well, sort of easier}. Go figure.....

"Welding the kick spring" back together would worry me...you'd loose tensile strength in that area from the heat used to weld it and possibly make a new weak spot to bend or break. Not saying it couldn't be done, but it'd be like trying to weld the typical early hemi head crack that happened when they overheated..50/50 shot on the repair lasting. Sorry...back to Glenn's build....

Maybe a kick start spring from a dirt bike would be the same size and bend on the ends?

That Hodaka part Bob showed looks darn close. I also found one on ebay for a Benelli Buzzer that looks really good maybe better also, but no measurements were given. I sent the seller a message...

Well, I took a shot in the dark with the Hodaka spring, though from pics I suspected the wire was of a smaller diameter.... it was. Otherwise its darn close.
I tried it tonight, but it wont return the lever. The spring is deflecting and going into a parallelogram type of shape and losing oomph.
The Hodaka part sits in a cup with a hole for the tab to stick out of. I think this is to keep the spring straight.

Im going to open up the hole in the center of the cup so it fits over that key and collar on the shaft and try again. There is a washer that locks into that key and has hole for the spring.

Well the spring was a fail. It showed promise and worked a bit until it popped out of the holder. I opened it up and found galling inside where it was scraping.. moving on. I pulled it out and closed it up sans spring. I'll make an external set up to be connected to the stop arm. Should be simple enough. I took a look at the carb to find out why it crapped out last time. I found rust sediment in the carb inlet and bowl, plus the gas smelled border line bad. Interesting that the same gas was in my weedwhacker which ran poorly today unitl I put fresh gas in. Then it ran good. It didn't help. Funny that a tiny, simple carb can be suchba PITA. Need to recheck it.


I rode it here.... then pushed it home.

Latest update.........Holy smokes my calf is sore from kicking that thing 9 hundred million times on Saturday......

Lol looks cool though

Yeah...I had the same issue on my old H-2 when setting up the jetting and the like...you feel it the next day! My KZ750b was easier as well as the CB750s...I actually miss a kick start.

 

[dorkburger]

I need to get going on this. Last few weekend have proven the old good intentions saying....

 

[dorkburger]

..... there has been no mechanical fettling in the garage since I pushed the scooter home. Been busy with other things, and the garage has become a mess. The scoot has slowly been draining its oil onto the floor. Found a touch of motivation last night and made a cereal box gasket. I couldn't be bothered to wait to buy gasket material. Motivation would have likely been lost.... cut out the inside and left the outside oversized and installed with a thin coat of sealer. Ive heard of it working, and it was easy so.... A compression fitting ferrule worked perfectly for punching the bolt and guide holes. 3/8 for the guides, 1/4 for the bolt holes... I'll add oil in a day or two and trim the extra.

Frosted Flakes boxes are GREAT for this!

Husqvarna used a similar looking spring. Might be worth asking the eBay seller what the dimensions are.

Thanks. I'm beyond that now though. Not sure how the mechanism works inside, but even without a spring, the kicker engages, and releases when the engine starts. If / when I get a good tune on it and it starts easily, I could even loop a strap around the lever to hold it up when riding. Currently I'm thinking that I'll grab the long skinny spring I saw at home Depot attach one end to the kicker and the other to the frame somewhere. I'll still keep an eye out for the correct part though.

Cool on the cereal box. Hopefully Honey Bunches Of Oats works equally as well. I did find a full gasket kit on ebay listed by an Italian seller, with the ad written Italian...... I'll see how this works first.

With regards to the spring, you might find a local spring manufacturer (or a friendly guy there?) who'll build that spring for you for a good price.

Alternatively, from what I gathered, one doesn't need much more than spring steel wire and a vise to build one...hmmm

 

[exdirtbiker]

your local NAPA has a roll of sheet gasket on the shelf. I've used it for lawnmowers many times.

 

[dorkburger]

Its been about three days since I trimmed the "gasket" and added oil. The fresh piece of cardboard under it is still dry, as is the seam. Of course with this cold weather I could probably take the cover off and it wouldn't drip for five minutes....I did put in 5W 30 though....

Really neat thread. Just caught up on the whole thread.
If parts get TOO hard to come by, it looks like a four stroke pit bike clone engine would almost fit. 140cc baby!

Those black wheel hoops would look nice with a pinstripe.
