Hey, I just picked up a Sears Suburban 12 that runs, drives, and mows(deck not pictured). I was thinking of getting duallies as I intend to pull with it and wanted to get your opinion. Also, what do you think about a stack? Thanks, -MichaelSears Ss.jpg

Duals, while a factory option, wouldn't be my first choice as a modification.
Each pulling track is a different story and what works well for one, may be disastrous for another.
Many people around here use the widest sears chevron tires they can find and have very good results consistently... But that is on clay/dirt tracks up here in Pensultucky
Duals may be good for a couple of hard packed tracks, but will be a negative on most IMHO.
Also, take into account the additional strain duals can put on nearly 50 year old cast metal hubs and you could be looking at a breakdown.

Now, for the good news. You have a really great, extremely hardy tractor there. I have one just like it and its my favorite.
I use it for plow days and snow removal and it rarely doesn't make me smile using it.
One more word of caution. Whatever your neighbor/buddy/pulling friend/etc says, DO NOT try to increase the engine RPM's beyond OEM spec.
IMHO, there are 2 fail proof ways to guarantee you will blow up your Teccy engine:
run it out of oil
Over rev it.

 hey i just read your post  heres my thoughts  in stead of duals try and find the widest agro wheels you can with out chaning wheel plates or hubs ,their out ther believe me youll get more bite with less strain on the trans re adjust your motor  lean it out sos not to heat as fast buy burning hot ,if you go with stacks remember these engins rely on a certin amount of back pressurd to keep them oiled, cooled, and firing on time, center wight your frame to keep tractor level when pulling , try to widen out the distance on whe front wheeles a little to heep side to side motion to a minum,run a cuple of cross bars to the frame side to side to keep it from twisting or bending out of line add a few supports to that front end remember it alum or fiber glass or maybe you got lucky and have the cast iron one ,-- my picture is my pulling tractor witch i have now returned to its orig, state of being, it wone 12 times placed second 6 and third 2 times and overall winner 5 times not bad for a 1974 16 hp sears suburban 25 pulling contests befor i stopped doing it - by the way heres what it looked likewhen i first got it, http://i61.tinypic.com/zn8p08.jpg,

Hey there, I was wondering why flame and or sparks shoot out my exhaust. The engine runs fine but when I throttle it up, sparks and or fire come out of my muffler. Is it running rich and that is unburned fuel catching fire? 

Thanks,

Michael

Are you back to a muffler of any kind or just straight pipes?

I would adjust the carb a little, but don't lean it up to much as they run cooler when a little rich.
Also, may try a different muffler with more baffling and quieter tone.

I agree, play with carb a little.

Does it have points? Maybe they are dirty and need cleaned? Just thinking it maybe have a slow fire thus slightly throwing off timing. 

 

Wondering if it maybe has a slightly burnt valve or it's hanging open enough to push fire out exhaust on compression stroke when firing.
