Levi 2 #1 Posted March 26, 2019 I have a Tecumseh h35 and I was wondering if anyone knows the btdc spec to time the magneto at. Is it .080 or a different number? Share this post Link to post Share on other sites

classiccat 548 #3 Posted March 26, 2019 Here's a good throwback video if you're unsure of the procedure...straight from the horse's mouth! It made a big difference on the two tecs that I performed it on (H50 and H70). Share this post Link to post Share on other sites
