twins

[Simpleton7016]

If it is not yet evident, it will be soon. I am not much of a mechanic. Maybe that is why I love my tractor so much....because they are simple enough and the manuals are helpful enough to get me through any and all problems I encounter. Not to mention help from y'all. But here is what I want. I love Elon's twin puller. The paint is cool, but I think the twin stright stack pipes are just awesome. I would like to do something similar (though on a lesser scale) for my everyday lawn tractor. I would love to tick off the neighbors! Is the twin 18 the engine that: 1) is most compatible with the rest of my 7016H or 712? 2) Is most likely to pop up on e-bay or for sale through other channels? 3) The smallest engine with dual exhaust? and 4)what is a range for one of these such dual exhaust engines in running or rebuilt condition?

Hi, Just a note of caution. I thought it was cool to mow with a straightpipe on my 3212h 35 years ago. I ran it that way for a couple of days. I lost about 30% of my hearing and have never recovered it. A lesson I learned the hard way. I would think muffled twin pipes would be better, and probably make your neighborhood better. Remember what goes around comes around. Good luck, Al Eden

Most any twin cylinder engine will have two ehaust ports and thus capability for using 2 separate pipes rather than joining them into one muffler. The 700 series were not available with twins from factory. Elon had to do some modifications to the frame to make the engine fit, and most likely you would be looking at changing some wiring too. As for availability, horizontal twin briggs should be fairly common, and were made I think up to 18hp. Unfortunately they do not have a cast iron block but some have cast iron sleeves. I have a 12hp twin in a Snapper LT series. Try looking at local shops for used ones, put out an ad in the paper, or you can try ebay. Price could be an infinite range. Verticle shaft briggs twins go for around $100-$200 in my area. I don't know what the horizontals are going for.

Chris is correct, I had to notch the frame for the heads to fit in, as well as fab a new engine pan and rear crossmenber. I'm a welder so I did my own work. I'm not sure what it would have cost if I had to pay someone to do it for me. The stock wiring did not work with the twin, so i had to run all new wires. I'm sure I had to do more but those are the major one I had to over come.

ERIK you can do this. i put a 16 twin cly B&S IN A 416 A/C i also put a 18 twin cly B/S in a 312 A/C JJ

Thanks JJ, to give you perspective....I did not know there is such a thing as a 16 horse briggs twin. Do these pop up now and again on e-bay? Is it a desirable and reliable engine? Will it fit in a 912 without cutting? Or very little cutting? Point well taken Al, I may back out of this hair-brained idea given that the only time I will likely be able to mow is when my 1 year old and 2 year old are napping! A "cool" sounding tractor may be counter productive! But rest assured, I ALWAYS wear earplugs!

Erik, a Kohler twin will drop right in a 912 with a little side frame rail cutting. The 900 seies has the right pan and holes to hold all the Kohler flat twins and v-twins. I have seen some singles (a 916) that had the lower side rails. I have put a KT19 in a 912 and the side rail cutting took all of 20 mins with a sabre saw. Everything else bolted right up and plugged right in.

I think you could get a Briggs twin in 12,14,16 and 18 HP ratings. My brother in law has a Briggs horizontal twin 12HP on his wood splitter.

ERIK i don't know what the twin 16 B&G came off of. a friend of mine sold it to me. i didn't ask. JJ
