Precision Airmotive LLC How about the basics?
Oh, come on. If the manufacturer did really "tighten" the bolts, then they
would have had to "slip" an entire thread on every pitch. Fixed threads don't "slip" if they are worn, they jump threads. If the carb body was this worn, the "tightening" would have completely stripped every pitch and they wouldn't have been able to torque the bolts down. BTW, a screw has a slot, a cross, or a keyway. A bolt has a hex head. Me? I use the hex bolts but I replace them with drilled head bolts and use both the bendmeup tabs and safety wire as well. There is nothing in the manual that says you can't ADD safety, you just can't do less.

The screws have bend up tabs that are bent up to keep the hex head screws from backing out. The only way you would know the case was loose would be if it were so loose you could see the gap in the seam, or bend the tabs down and then tighten the screws, and then bend the tabs back up. But who would think that would be necessary with a newly rebuilt carb shipped from the manufacturer? I think they did tighten the screws, but the threads were worn out inside the carb body, the screw threads slipped. Wasn't my fault! It was carb manufacturers for shipping such a sloppy piece of crap. |

I wrote Precision the following letter, and got back a reply.
I would like to know if your company will still manufacture the SilverHawk fuel injection systems? And what about carburetors for experimental aircraft, are they to be discontinued also? And companies like Kelly, that rebuild your carbs, will they be able to do so, or was Precision the only source of approved parts for the float carburetors? Are there other companies that manufacture STC'd parts for your carbs? Their reply, We are continuing to sell all of our fuel injection products. We are not able to supply any carburetors or components for any purpose. Precision has no affiliation with Kelly or any other aftermarket PMA carburetor parts manufacturers. From what they said, it seems manufacturers like Kelly Aerospace do indeed manufacture parts for the carbs, so about the only thing that won't be available are the actual carb bodies. And there should be enough of those around to last the G/A fleet for a long time. I suspect parts prices will go up though. The key words in their reply was "other aftermarket PMA" which means other companies can manufactures replacement parts. That fact should keep us flying. |

Jim Damn, I got ripped off, my machine supply house just sold me a couple pounds of 1/2" SAE hex head cap screws. Must be some kind of government conspiracy though, as I also have a bucket of AN21 "Bolts" out here in the shop that obviously aren't bolts no matter what the AN spec calls them. What else have I been lied to about? Looking in the bin under my bench now...Oh my god, I really am screwed now -- I have bins full of NAS stuff, all labeled "bolts" that can't possibly be bolts. At least my Torx screws are authentic. Charles |

F.U. bud, what good advise? None I saw.

I'm the one who flew the plane home with a leaking, brand new carb, not you mister know-it-all. You don't need to disconnect the safety devices to check for tightness. First, you wiggle the bowl. If it wiggles or twists, the bolts are loose. Then, you put a screwdriver on the screws. If they wiggle back and forth against the safety tab (or if they have any in/out slop indicating a jumped thread), *then* you remove the safety tab and figure out why the screws are loose. Alternately, you could skip all those steps and save enough time to make a handful of obnoxious posts on usenet. KB |
