Hey guys , I have a question for those of you who have experience with the HH120'S. I have one and the ignition module that is above the flywheel is bad . I have been toying with putting another engine on it but I just cant pull the trigger on doing that. If I convert to the automotive ignition what other parts on the HH120 give trouble? The reason for considering another engine is the replacement cost of the ignition part which is 169 bucks. What are ya'lls thoughts and opinions? By the way this is on a sears suburban,just don't tell anyone I am here asking.
