Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello. Thank you for choosing Just Answer. My name is***** will be happy to assist you.
You are correct. Your engine does have hydraulic lifters, so this eliminates the need for adjusting your valve lashes. You have done a very good job of covering everything. Did you have gas inside your crankcase?
The black smoke was likely caused by your carburetor flooding. Now that you have rebuilt your carburetor, I do believe that our problem has been resolved. I would also replace your air filter.
You and I can continue from here.
