The piece of spring steel arrived yesterday. I will let you know how I make out with it. Thank You..!!

Thank you John...

Hi John, Well my feeler gauge experiment was a failure. The material probably has too much tension. It would not prime and would not run, so I assume it is putting too much pressure on the ball. If you can send me a piece of the material that you used, I would sure appreciate it. I don't know if you are a fan of Bring a Trailer, but I visit the site occasionally to look at all the vintage cars, motorcycles, mini bikes and go kart of yesteryear. I saw this micro-power micro-bike. Is this the same type that you have or had? I posted a link below. https://bringatrailer.com/listing/micro-power-micro-bike/ Thanks, Bob

Hi John, I made a spring out of a feeler gauge, but I have not installed it yet. I will try to get to it tomorrow or Saturday. If it does not work, I will take you up on your offer. Thanks, Bob

Hi John - Don't worry about it. I thought maybe you had a surplus of them. I will try making one from a feeler gauge. I have several laying around and will match up the tension and then cut it out and make the bends. I don't know if you have ever seen a video of the USPS letter sorting machines, but they have vertical rubber rollers that apply a lot of tension to the envelopes to keep them running at warp speed. It was not the whole spring that broke, just the very ends where they are cupped to rests on the diaphragm roller. That is what I found in the envelope. As I mentioned, it runs fine and may never be a problem, but it just kind of worries me that one of the legs does not sit on the diaphragm roller and that in turn makes the diaphragm arm sit a little bit off center. I will let you know how I make out. Thanks, Bob

Hi John - I mentioned that the two legs of the diaphragm arm spring were shorter than they should have been, one more than the other. Well, I found two small pieces in the envelope that you sent the spring in. The culprit was probably the high speed sorting machines that the USPS uses. They put a lot of pressure on the envelopes when running through the sorting process.

Hi John - The diaphragm spring arrived today along with the diaphragm and gasket you included. Thank you for that. I installed it and got the Tiny Tiger 300 running. The one you sent is working but it appeared to be worn at the two ends, where it cups and should rest on the diaphragm roller. One side barely rested on the top of the roller and the other side was slightly shorter, so it does not make contact with the roller. I made sure that the spring was in as far as it could go. Like I said, it is working, but I don't know for how long. With one end of the spring sitting on top of the roller and the other not on the roller, it makes the diaphragm arm slightly off center, so I don't know how long it will run like that. I was wondering if you have another diaphragm spring, in good shape, that I can buy from you? Don't get me wrong, I am grateful for the one you sent, but would like to have a good spare in case this one does not last. I am more than happy to buy it. I mailed you $20.00 for the spring, diaphragm and gasket that I received today and you should have it by the end of the week. Thanks again, Bob

Does anybody have a carburetor arm spring for a Tiny Tiger 300 that they would sell? Mine has one of the legs broken off. Thanks.....

I recently purchased a supply of the 1/16" and 3/32" chrome steel ball bearings used for check valves in most of the O&R carburetors. These are high quality ball bearings precision rated G25. If you need some, just drop me a PM.

I received it....Thank you....Put it on my " I Owe You" list. Just don't send the Godfather to collect it.... Thanks again...!!

Thanks for the heads up on the brake fluid. Walmart is about the only place that I did not look. Like you, I had an old rusted can in the garage for about 30 years and finally pitched it never knowing that I might need it in the future. I will visit Walmart in the morning. Were you ever able to mail me a grounding strap for #2? Thanks again, Bob

Hi John - Where in the world do you find DOT 3 non synthetic brake fluid? I have tried to find it, but all the auto parts stores that have DOT 3 only have it in the synthetic formula. Any ideas where you might be able to find the old stuff? Thanks ~ Bob

Check the spark plug.

My guess is that the point have a build up on them. If you already cleaned the points, then a tiny piece of debris got into the points, which will make them run like poop. It will misfire, backfire and stall out.

Once the governor shaft is in the carburetor, it will stay in. It is a loose fit, but it does not come out. Sometimes it is a little tricky getting it into the hole in the carburetor and keeping it in the hole while you are mounting the carburetor, but once you get the carburetor mounted, the shaft will stay in the hole.
