Default I want my pull start off.. Help?

Will it be ok if i just remove my pullstart on my Hyper 8 port .21?
It always is in the way and now it will not retract, so i want it gone.

ok i have cut the rope off and now i need some advice, I have heard that no pullstart can help a motor out a little, less drag.... so now should i put the pullstart shaft back in the hole in the motor? Or leave it of and put the cover on and be done? Or do i need a new backplate?

yes you need that in otherwise dirt and stuff can get in the engine. go you your hobby shop and get a non pull start back plate for your motor

will that cause a loss of power? By some drag on the motor? I got it in there but the string and the coil spring is gone.

Having no spring and string in there to stop the bobin from spinning will create a heaver moving mass. There is no stress on your engine from havinga pull starter on. It uses a 1 way bearing, so that when you pull, it grips, but when the engine is turning, it slips I would have left it as is, for example if your starter batts run out

i'm raising the dead back alive -

but quick question. i'm a tight arse and want to use the existing backplate from the pull start (less coils and strings and shaft). will that work without causing any harm?

the pull start bit of a waste of space and i hardly use it.. any advice, thanks

what i did when i ran nitro back in the day was that i took the pullstarter off, and all the crap in it..along with the shaft thing that went into the engine, and just took the cover of the pullstarter back on and sealed the little hole where the little string came out before

yeah thats what i did... but i rang my hobby shop today and they told me if i put the plastic bit there may be an oil leak?

i had a look at photos of the backplate and the dimensions appear to be the same. obviously you cant judge it by the photo but it wouldnt be much difference since the backplate sold does not come with the shaft anyways.

i might just buy a backplate, fix up the pull start and sell it...

this is strange, but when i took out the pull start with the one way shaft, the engine was very hard to start up. usually a few yanks on my starter box will get it started but since i've taken it off it took very! long.....and when i managed to start it up it got hot VERY quickly on idle, went to 90 degress C without acceloratiing...

my theory is that when you taken out the shaft, there is no air compression, since the shaft itself fit neatly around the hole.

I've decided to put the shaft back in with the backplate. the engine back to normal. very easy to start and no lose of power...

well anyone whole intends to change their pull start should take note on the above. this was my own experience i know its not the same for all.

but the engine i was running was a Hyper 7 - Mach 28

cheers
