Status: offline 		Brand new Savage 25 RTR.
Run about 2 tanks through it.
I'm guessing the one-way bearing is shot. The Rotstart will turn the motor over if the glow plug is out, but under compression the rotostart just spins.
Pulled the motor, took off the rotostart assembly. The bearing looks ok, but I guess that doesn't reall mean anything.
Anything else I can check?
Thanks,
RR

Status: offline 		Of course hes not mcguyver, he can make real parachutes from tents in 5 mins and powerful exposives from a rag, a bambo chute and swamp gas! aluminum foil is perfect to use in an engine, i use aluminum foil tape to make high compression gaskets fro my gokart motors, and they hold up longer than real gaskets

Status: offline 		Savage SS same problem. You are lucky you made it through two tanks. I only got through the initial break in tank. I wonder if the roto-start may cause too much stress on the one way bearing.

Status: offline 		I've went through 2 already with my ss and roto start. If I had it to do over I'd sell the roto and put the pull start back on.

Just make sure when you start it to loosen the glow plug about 1/4 turn out. You'll get a good feel for how loose to leave it. That will take some tension off but I still think thats not enough to solve the problem.

Status: offline 		Went down to the LHS and they said the one-ways are on backorder !
I have no problem with stuff breaking, it's all part of this hobby. I do expect to be able to get parts though!
So I call HPI(took about 20 min to get through)spoke to a guy named Fred. Well Fred said he'd grab me a one-way off the assembly line and a couple extras if he could.
Thanks Fred!
I feel; better now
