[ATTACH] [ATTACH] Greg, I hadn't even thought about it, it's a great point. I have been distracted with fabbing some linkage. The cardboard is a...
Finally! My fuel fittings came. Some assembly required.
The SAGA continues!! Today I tried my hand at heat treating! After checking a Hilborn Spool and determining they are around 60-65 Rockwell 'C' -...
Hi Greg, No I haven't, but that's a good idea.
[ATTACH] [ATTACH] Idle ramps machined and secondary bypass holes drilled. This thing might even work!
[ATTACH] [ATTACH] In process Barrel Valve Spool - the extra material is there to facilitate manufacture. This one is really a test to check out...
Loudbang, The spool very precisely controls the fuel at idle with a very shallow ramp - a controlled "leak" if you will. Depending on the size of...

Holy smokes THAT'S a huge slot!!!! Must be for nitro!
Thanks Greg, yeah I'm not worried about it. My daughter lost a head gasket on her Honda. IIRC the spec was over .002" and it needed resurfaced...
[ATTACH] The surface of my fixture is pretty flat <.001" - I will eventually put it on the surface plate and see just how flat it really is, but...

Rich is this where I learn that you retired from Hilborn or something similar?? :-)
Rich, I hear your words and I wanna think I understand, but it falls apart in my head and when I sketch it out. If I orient it as you suggest then...
