Guys....thanks for all the input!!
I don't want to turn this into a .21 vs .28 thread either. I think a .21 is a great power plant for truggy, but it seems you first need a really good .21, and second you beat the hell out of it cuz you're pinned all the time. I'm just looking for reliablity, and a .28 that I won't beat into the ground after 2 gallons.
I've heard the Jammin is a good engine, and a few here agree. I just want the thing to start and not looking for the fastest .28, just most reliable. I will race this maybe once a month, buggy is my first priority.
Any others?
