hi I'm going to be using a bumpstarter and i want to take the pull start off and i want to know if i have to put something on the back of the engine where the pull starter was or if it would be alright leaving it open please help
 
I think you are suppose 2 use a back-plate but I'm not sure on that.....
 
Diver's right. Leave the pull start on. If you want to ditch the pull start, there will be a fair amount of work to do to make it right. Depends on the engine. Typically you'd have to find a non-pullstart backplate and modify the crankshaft or buy a new non-pullstart crankshaft. If you just take off the pull start, you'll have massive air leaks which will cause the engine to run poorly or not at all.
 
well it's a OS CV-RX and does anyone know where i can get the screws to hold it on to the backplate cause i only have 2 holding it on,
 
is it the 18 ??? good choice w/ engines .... OS Engines are the best...

No, it's the .15. Yea has alot of power, still can't tune right cuase its too damn fast on the street.
 
I'm just a noob... but i think i would just remove the one way bearing from inside the pullstart than put it back on because I've heard from a few people here that the pullstart causes drag when the engines runing. and without the one way the pullstart is disconected from the engine but your still covered

:2cents:
 
Yea i love the OS engines they have alot of power...

Reterded pilot, sounds smart ... i wonder if it would work ???
 
No pilots idea wont work. The crankshaft on a nonpulll engine is too long to do that. Just leave it on!
 
i dont understand what you meen bandit....as i understand it he has a pullstart engine right now he just wants to use a bump box instead of the pullstart....so i dont understand what you meen by the longer crankshaft on a non-pullstart engine............trying to explain what i do know about rc`s nitro & electric to my wife makes me really think about everything that can and does go wrong with these things and its curius why we pick this as a hobby....do we just like pain? :boxing:
 
yea, i don't see any thing wrong with taking the one-way bearing out and putting the pull starter back on..
 
you will reduce some weight off the car if you eliminate the pull start you will find the back plate @ you Lhs just call first O.S. is a brand that a lot of shops carry so it should not be hard to find
