    Hi Sirhr. Were you able to get that Timeless intake to work? (I only check this forum every so often, and just saw your thread). It sounds like you have checked the fuel flow at the carb. One thing that I like to try is to flood the carb with the tickler button on the float. If the motor runs better, then it needed more fuel. If it runs worse, maybe it needed more air. Also, are your loops in the copper fuel line horizontal or vertical? The old bikes always used horizontal loops to prevent any air bubbles from forming and stopping the fuel flow.

    Did you drop any powder graphite onto the valve stem? It might not last long though. Try a squirt of 3in1 oil while it is running to see if that helps. Also, the intake valve springs can be tricky to dial in. A stiff spring is better for higher rpms, but a weaker spring is better for low rpms. When you let the bike run for 30 seconds and then it dies, is it running at the same rpm the whole time? Or is the problem related to the motor speed?

    Keep at it, you'll have it on the road soon. I really love the idea of buying a Timeless and riding it, modifying as needed. They are very affordable compared to the 100 year old bikes, but give the same feel when you are going down the road.

    regards,
    Pete

    are the timeless chassis very good? i've seen a couple for sale with real hd motors in them. seems like an affordable way to ride a pre 16 without worrying about damaging a real one.

    I really cant say what the appearance is of the frame, i dont have that part. I was asking for guidance with the carb tinkering with spring rates for air valve, and the engines intake spring rate for proper running, so if anybody has answers thatll be great!

    Flyin.mauer!

    Our member Tommo posted H model airvalve spring pressure instructions, adjusted in the middle of their adjustment travel, depending upon the carb size. (3 oz and 5 oz, basically...)

    (I recently encountered a very early 3/4" screw-on, with a very well preserved spring of a very small gauge wire, that was much less.. so its a good thing they are adjustable!)

    I am totally ignorant of the modern reproductions, so photos would be appreciated, thanks!

    Thats pretty cool to know that 3oz for the small schebler is what it takes to unseat the leather valve. Mike lang has told me his motor idles real sweet with a spring having only 2oz before it unseats, and this makes sense as most everyone has over rich running troubles. Id like to find where i can get a teflon replacement instead of leather so it isnt a factor either
