Winter Carb Kit Suggestion

[SmilinSam 3,914]

Take a 9-16 hp Briggs cast iron engine shroud and cut off the top part and discard what you see below: [img]http://a4.cpimg.com/image/0C/10/53092364-872d-02100182-.jpg[/img] Then get a extra air filter cover and put it on your engine. Hold the shroud piece up to it and trim away the material at the bottom and around the exaust pipe to fit it in place. Thenmark where the shroud part meets the air filter cover and remove cover, then weld the two pieces together.

Great idea Sam. I have had problems with carb ice with my Homelite in past winters - bet this would solve it.

Clever idea. Based on my experiences it should work great. I used a heavy canvas across the throttle area along with the factory exhaust shroud.

Gee Sam, I think I have everything to make that with already. Good idea!

I thought the orriginal design was made where it allowed some air flow from the hot muffler to surround the linkage area and carb giveing it some heat. Will this one allow for some heat? All I'm seeing is the notch for the exhaust, blocking incomeing snow. Still a great idea Sam. Nice job on the fabrication.

It was, but with this one, you catch just enough forced warm air coming off the engine from the cooling fins on the block that you get a nice steady stream flowing through my contraption, around the carb, and exiting out behind the carb to keep the ice well melted. Yet, should not be enough to cause any heat problems with the fuel system.

Will I need one of those carb. heater things here in S.C. Temp is mostly above 40s in winter time. Just fun en with you fellows up in the cold and snow. If we get snow here, I never think to put the blade on to push it. Normly gone in a day or to.

[D-17_Dave 12]

I gotcha Sam. I figured you would have thought about it. Being as I don't have to deal w/ as much severe snow I was wondering just how ness. it really was.

Sam, Great idea, but I must protest sacraficing a perfectly good blower housing from such a venerable diminishing population of engine family out there. Why not substitute one from a much more plentiful and more likely junked model series like the 4&5hp (100202, 130202) and the 7&8hp (170000, 190000) instead? There are always plenty of them at yard sales/tractor-engine shows with ventilated blocks. When was the last time you or anyone saw a 10-16hp cast iron Briggs with an extra inspection hole through the block? Tom(PK)

Speaking of that -- would the shroud from a Kohler K-series work as well? ;)

[SmilinSam 3,914]

The smaller BRiggs shrouds may work for engines that have the short intake neck, but for the long intake neck you'll need a shroud from a bigger engine. I think Kents right in that K series Kohler shrouds from 10-16hp engines would also work. Theres alot more of those from blown engines than there are Briggs 9-16 hp . As a statemnt of fact, that Briggs shroud was from a 10 HP Cast iron that had a hole blown in the side of the block. Thats the only one I've seen with that problem in all the time I've been junking tractors.

[D-17_Dave 12]

Someone should tell Graham that us Briggs fans have finally found a use for some Kohlers.lol

If anyone is interested, I have made a template of the original style for the 10hp,12hp and 16hp Briggs 1957-1972 B-Series/Soveriegns. If interested, I'll post the template.

About the only thing that might be a problem as I can see, is the chance of vapro lock from the fuel becoming too hot in the line. If that is a problem, the engine will not run, and finding the problem might prove interesting. Usually, rubber or plastic lines do not have the problem, but.

Just for information if you wnat the origanal briggs carb kit. Norm Yetman has a ton of the original kits.

Here's what I did; took two pieces of HVAC sheet metal, cut one & glued to inside of hood, the other was cut & screwed to side of carb using unused screw holes, when you close the hood they close off the side of the cover & keep the carb just toasty enough to stop icing. Not as nice as Sam's, but quick & easy!
