Me too...glow forever! What they were intended for
For others reading this and dont know Av8tor, he has been very helpful and on point regarding engine conversions (ie; weed wackers, blowers ect) before they died off. All without coming across as condescending. Just my opinion based on his posts here going back a few years.
I think Ill break out my 4 mix and run it up, just to hear it. Its been a few years.... last thing I did to it was make an exhaust manifold out of copper tubing and a muffler out of a hair spray can. I might have lost a few rpm putting a muffler on it but I prefer the sound over the harley/ratty sound of open exhaust. Not the prettiest piece of metal to look at but was and enjoyable project. The engine was free so why not
