Did you really mean "redhead .35" in the text? It doesn't match the title, of course.
The rear intake .29 NV assembly will be hard to find, but it's a split spraybar like a rear intake K&B .40. I'm fairly sure that the K&B parts will fit and work, but that isn't likely to satisfy your intent. The one RH .29 rear intake I saw run was on suction, and of course, it requires pressure feed of some type or other. I'd check in MECA (or is it MECCA?), eBay, or last resort, MECOA/RJL. The McCoy NV was smaller diameter than the K&B parts, and might be less likely to be straight. Any runout would make the mixture setting pretty flakey at best, pressure or not.
Early (glow) speed fliers used pen bladder tanks, but when the ballpoint pen came about (due to NASA and their new fangled space ships), those became difficult to source after about the mid-'60's, when I used them. Do you happen to remember what ol' Dad used for a fuel system? If it wasn't pressure feed, that would explain the crappy running. Steve
I meant 29, of course.
This one has always (since I was 5 or so, which was a long time ago) an "across the choke" spraybar and it looks just like the others I see, and I still have that, just no needle valve. The part I am finding hardest to find is the prop nut, which looks like the nut on a Fox shaft extension.
With the gigantic modified venturi, it ran acceptably well in an airplane he built for me = a Top Flite Superform P-47. I had been flying 1/2As, so I could fly, but with the hot-rod McCoy, this heavy airplane with a mere 27" span pulled FAR too hard for me (at about 8-9 years old) and I almost panicked when it finally got up to speed, because I thought I couldn't hold on to it. But, otherwise, it ran and needled OK on the old Perfect square tank.
If anyone was doing anything with pressure in 1947-48, he almost certainly knew about it, because he flew with one of the two big groups in Little Rock, AR. There was the "Kingfish" Sadler group, and the "Bob Veazy" group, he was with the Veazy group, and they were bitter rivals in Little Rock at the time, and their clubs took turns setting records for a while.
He claims, er, claimed to have set the last "B" Speed record *under* 100 MPH, he got beat the next day by the first person over 100. Or at least that was one of the most plausible versions of that story. Phantom P-30, some "hollow log" Mustang kit with the radiator sanded off and hollowed out to "paper thin", and a 9-16(!) prop! I saw a picture of this thing, I don't don't know about 16" of pitch, but it looked like a paint-stirring agitator, the pitch was so high.
He then saved up for a McCoy 29, never ran faster than the Phantom. He said the Phantom was the only engine that he was always sure he could get started on ignition. Then, a mere 25 years later, he modified the McCoy and it ran like, and I quote, "a spotted-ass ape".
