i looked at my ground and it seems secure tugged on wires and seems good. i am having somewhat the same issue but i had mine running for more than 30 mins and let it sit and cold start it and it wont turn over had to keep adjusting the lp reg and idle adjuster. did a full tune up, cleaned carb, and repaired some broke wires again from someone who done it. mine backfires when it stalls and relay keeps clicking without key off. is there something else im missing out of the troubleshooting?
