Fine thread needle valve
After seeing a few threads about the prices on Ebay for the KK fine thread needle valves, and having bought one from Texas Timers a few months ago. I checked Texas Timers, and they are sold out. Expect the Ebay prices to go nuts now. I should have bought more when I had the chance.

Re: Fine thread needle valve
The needle valves have been out of stock for nearly a year. There's really nothing special about the fine thread needle valve as it was used in many of the product engines of the 60's-70's. That can be easily sourced. The TD requires the main body assembly and even that can be had by purchasing Matt's assembly from EX Models. The stock spraybar could be removed and the new spraybar installed for less than what Texas Timers offered them for. What many don't realize is that many needles from r/c engines can be substituted to use remotely with equal to or better performance. http://www.exmodelengines.com/product.php?productid=18273&cat=266&page=2 Not to mention the included venturi which can be drilled out more than stock and easily switched back if pressure is no longer a option.

Thanks Ken , I didn't know Matt had those TD needle valve bodys , Bernie don't when I was looking not long ago for one . Should have thought to look knowing they don't carry the same inventory

Re: Fine thread needle valve
I use high pressure bladders, therefore the 80 thread per inch needle proves problematic. That doesn't mean that it won't work as latex tubing offers a lot less pressure and I have never tried it. I know it was mentioned on here that Red Caps works well even using the stock needle. More than likely this is due to the low pressure they offer. There's always a catch it seems as I have found that most lower pressure offerings don't hold up to high nitro, sun, heat, etc. So if you do try it, I highly recommend placing a party balloon over your bladder to prevent a rupture as this would help encapsulate the mess.
