F-19 carburetor

[1piece@atime]

I was wondering what carb you guys and gals a re running on your 0-200. Im experiencing a lean mixture problem between 1800-2400 rpm when the temp drops bellow freezing. I’m using a 10-5128 and would like to swap to the 10-4894-1, I’m having a hard time finding the differences in these to carbs and why mine is using a odd carb. Thanks...Adam

There is a Continental service instruction for this. see post 2 in this thread. http://vb.taylorcraft.org/showthread...t=filter+cover

Here's the same story from another Forum: http://www.supercub.org/forum/showth...180#post705180

It's interesting this has been noted. I've not had that problem on three small Continentals in cold wx but another local Taylorcraft pilot apparently had and installed the front baffle. Not sure of his results re static and in-flight ops.

Edit: I see Adam responded to the other Thread with very good info from Marvel. Makes sense.

Re: F-19 carburetor

was able to talk to someone at marvel that knew these carbs. The carb I has a strait nosle and the modern and more common carb 10-4849-1 has a atomizing nosle. He said that some of the older cylinders had different porting that ran better with a strait nosle. When I experienced these symptoms it was between -6 and 10*f and by using carb heat I was able to get it to run smooth at the lower cruise settings. I’d have to leave carb heat on during run up and once I was WOT I’d then shut the heat off and get my max takeoff rpm, I’d doo the same if I wanted to do a full power climb. It works but just doesn’t seem right, especially when the Cessna 150 I used to fly ran smooth at these low temps without carb heat. This past weekend I made a plate similar to the one in the service bulliten and it made it run smoother but it was too restrictive ended up cost me 150 rpm at static. With skis on the lack of power was very noticeable. Thanks

Re: F-19 carburetor

Hi Adam, I'm not chasing you around to be a bother but what you discovered makes sense and is important info from Marvel. I currently have a C-85 Stroker in my Taylorcraft (same displacement as an O-200) and it runs ok so far in the cold. But I have read here and elsewhere of the cold wx ops issues with some engines but rarely do the posters note the model carb and other stuff. The baffle bandaid bulletin was from the '60's and i suspect the carb manufacturer has since improved their design as you note.

Thanks for taking the time to contact them and share their reply.

Re: F-19 carburetor

I’m planning on getting a overhauled carburetor for it. I’m gonna get with my mechanic buddy to figure out which one to get. I’d hate to buy the same carburetor that’s on it and find out I still have the same issues. There’s a lot of good information and knowledge on these sites.
