Fordiesel69 271 #1 Posted January 20, 2016 After running my snowblower this week, I have had to leave my coveralls in the garage from the nasty exhaust. I was wondering if there are small engine cat avail that can be installed. Share this post Link to post Share on other sites

Aldon 4,828 #5 Posted January 20, 2016 For the price of a catalytic converter, i would think about adding some additional exhaust piping to route it such that it does not bother you...... I continue to ponder a rear exhaust system for mine. 3 Share this post Link to post Share on other sites

lynnmor 7,846 #7 Posted January 20, 2016 Does the engine use oil? Perhaps you might need some engine work. You might be running too rich, that will bring tears to your eyes. These older air-cooled engines do have high emissions, just make them run as well as possible. You might be able to cobble up a cat and make it work, but where would you position that extremely hot device? 1 Share this post Link to post Share on other sites
AMC RULES 37,196 #8 Posted January 20, 2016 I like 'em but, they really don't help 'em run much better. 15 Share this post Link to post Share on other sites
953 nut 60,241 #9 Posted January 20, 2016 Craig, it may not make it run better, but the warm seat is wonderful. 10 Share this post Link to post Share on other sites

Your carb is probably running rich. Sounds like it needs a tune to me. Share this post Link to post Share on other sites
Docwheelhorse 2,740 #11 Posted January 21, 2016 It does sound like its too rich... by ALOT. These old motors may burn more fuel and "pollute" more---but yours sounds like it needs a tuneup / carb adjustment. If your work clothes smell bad just think of how much fumes YOU sucked in.... If you did manage to rig up a small cat and it worked/got up to proper operating temp it quickly would be a glowing white hot "nuclear" furnace trying to burn all of the excess raw gas fumes coming through. It wouldn't last long. Tony 2 Share this post Link to post Share on other sites
