i have justordereda starers box will it be ok 2 just leave my pull start on ?

Yeah, you won't hurt anything. Just make sure the box rotates in the correct direction. The pull start will come in very handy if it flames out quite a ways away anyways, won't have to lug it back to the box or the box back to it.

i have a bump only engine and im glad i have it, for stubborn first starts or weak one-ways its a life saver.

oh, and get a gell cell- they have TONS of capacity on them

A bump-only engine would drive me nuts. Undoubtedly I would end up flipping that vehicle a lot while it's far enough away to stall before I can get to it. Then I'd have to carry it all the way back to the box.

yeah, i dont do alot of flipping anymore, and if i do flip, i have about 40seconds to reach it.

it is a pain that you have to lug it around, but it opens up a new field of high performance engines that are bump-only

I'm a basher, so pull start engines offer more than enough power for me. As it is my pull start .18 can spin all four tires on my monster truck. I have a feeling the touring car I just bought will offer it even less resistance in that department. I have been considering grabbing a bump box because they do have fits, but I wouldn't go to bump only engines.
