Review on Enhance Engine Performance with Honda 16620-Z8D-305 Thermo Wax Assembly by Carlos Long

I was surprised to find this part at Revain but found it and bought it. An easy to replace part, just watch it on YouTube and your mower will be up and running in no time. My mower was stuck wide open and spinning like a muta due to a non-working thermovox. I didn't discover this until I messed up the regulator setting. DO NOT TOUCH THIS ADJUSTMENT or you will regret it as just one micrometer adjustment makes a HUGE difference in RPM. It took me a while to get back to normal as that part was the problem. Nuff said everything works and YouTube is the bomb when you're doing something that's a little out of your control.
