R-1340 Carburator

[HarvardIV]

If what bdk said is correct, you've got some crusty old timers posting who are too afraid to fix their carburator due to lack of confidence. So, to them, if anyone asks about it, it can't be done.

Kind of like when Orville and Wilbur Wright flew the first plane, you had all the old man saying "If man were meant to fly, God would have given them wings".

So maybe it's time for the old crusty's to retire, or just bite their tongues.

Let's just put it this way....The shipping cost alone on the required equipment to overhaul a carb for an 1830 or larger engine is greater than the cost to send it out.

That is a pressure carburetor (containing diaphragms, not a float). A different animal altogether. Those require calibration far in excess of what is required for a float carburetor.

Didn't a Buchon "go down" in the 80's due to an "error" in rebuilding its "simple" float carburettor, here Texas? If my memory doesn't fail me, didn't an experienced mechanic make a "judgement call" in re-using the original float...because original replacements were hard to find or non-existant at the time?

I have never heard of a Buchon with a float carburetor. Some early Merlins had float carburetors (BoB era), but the postwar Merlin 500's used in the Buchons most certainly had pressure carburetors.

Hey Helldiver:

Why do you keep saying "cutting corners". Maybe I want to rebuild the thing just for my own interest. In addition, if you have the right equipment and the tech orders, then what? Are you saying the tech orders are wrong?

[HELLDIVERS]

HI IM NOT SAYING IT CANT BE DONE OR THAT YOU CANT DO IT,ITS REALLY UP TO YOU, BUT I HOPE YOU REMEMBER THIS CONVERSATION WHEN YOUR LOOKING FOR AN EMERGENCY PLACE TO PARK ALL YOUR HARD WORK! YOU CAN JUSTIFY THE REASON BUT THE REALITY OF IT ALL IS THAT ITS A FOOLISH RISK THAT YOUR BUILDING INTO YOUR A/C .IF YOU ARE AN EXPERIENCED PILOT OR MECHANIC YOU WILL KNOW THERE ARE ENOUGH THINGS THAT CAN HAPPEN IN FLIGHT THAT CAN CAUSE A CRASH ,SO WHY TAKE THAT RISK,IM NOT IN THE CARB BUSINESS NOR DO I WANT YOUR $1000.00,BUT I DO ANNUAL 4 OR 5 T-6S EACH YEAR AND AS A FELLOW WIXER ITS MY BEST ADVISE.THANKS MIKE

Helldivers:

Why do you consider it a foolish risk if you follow the necessary manuals? Again, I'm not hearing a people with carburator experience talking. I'm hearing fearful people who are afraid to try it. Look, if you follow the manual, and have the correct supervision you're ok.

[HarvardIV]

One more thing naysayers:

My grandpop is not an IA or A&P, and he overhauled his own engines with the correct supervision. He's now 85, he's still alive, not a ghost. Now comeon, I guess if you are scared, you expect others to be scared with you too. You naysayers put limits on yourselves.

You'll only go as far as your limit, so it sounds like you are stuck right where you are.

[HarvardIV]

Look if the manual says it can be done, I don't care what you say.

[HELLDIVERS]

GETTER DONE!!! IVE HAD PLENTY OF CARB EXPERINCE AND PLEASE LET US ALL KNOW WHEN YOU PLAN YOUR FIRST FLIGHT AS WE WOULD LOVE TO BE THERE WITH OUR VIDEO CAMERAS!!IF I DIDNT HAVE ANY EXPERIENCE WITH CARBS OR A/C THEN I WOULD CHEER YOU ON BUT ONLY ST. PETER WILL CONVINCE YOU THAT ITS FOOL HARDY TO GET A T.O. AND ATTEMPT TO DO IT YOURSELF.I DONT KNOW YOUR MECHANICAL SKILLS BUT IVE BEEN IN THE BUSINESS LONG ENOUGH TO KNOW THAT YOUR SETTING YOURSELF UP FOR DISASTER.GOOD LUCK MY FRIEND I WISH YOU THE BEST IN WHICH EVER WAY YOU GO.THANKS MIKE

[HarvardIV]

So I guess you're saying the tech orders are wrong.

[HarvardIV]

Chris,

You know what my friend there is this thing called the FAA and beleive it or not they check this site and you go putting up statements like this will only draw them to you like Moths to an open Flame.

Their is the right way to have an aircraft rebuild and then their is the wrong way and what you are doing is the WRONG WAY.

As Mike said good luck and let us know when you are going to do your first engine run so we all can be their when your Carb eats it self.

Bring em on, I'm doing everything by the book and legally. You're way out of line.
