Ok guys i have just got a new pull start for a hpi star 15 but when i go to put the pull start on the one way just slips and it is clean and working good it is the back plate i think the shaft wont turn the engine over what do i do ?....

Have you got the one way bearing round the wrong way? Just a suggestion.

[shiftypowers]

i dont think so mate the silver end in the pullstart and the flush side on the back plate ?

[Rusty1103]

Was everything sound before you changed the pull start?

[shiftypowers]

yeah i took the back plate off the the engine has i did a recon on the engine but i think its the inout drive it has slight play

[Rusty1103]

The shaft that the owb goes on to has play in it? This might be the backplate. This movement might be causing the teeth in the owb slip because when it grips the shaft, the shaft will move disengaging the owb. If it is possible take the owb out and put it in a small tub with a lot of WD40 or GT85 over night, this will allow anything inside to hopefully loosen and come out

i know why it is like that now what it is the shaft what goes on the con rod to turn it over it wont go on unless i push it on but when i put the owb on and the pull start it wont get on the con rod what do i do ?

[Rusty1103]

So it turns by hand? Try it in stages, fault finding. By hand on the shaft, by hand with the owb, mechanically with the pull start. Could you get a video of the problem harder to understand through words lol.

[shiftypowers]

yeah i will make one now rusty and thanks for the help dude

[shiftypowers]

thats the best i could do lol.

[Rusty1103]

hmm is the conrod in the correct way? or the pin that will go into the starter rod groove worn out? how old is the engine?

[shiftypowers]

the Engine has been used a bit tbh and could do with new pistion/liner/con rod but then its not worth it when i have a os 18 to put in just got some mounts of ebay hope they fit and it works fine but still on the 15 engine shall i just bin it or does any one want it as spears i dont need it anyways i will send the brand new pull start anyways.

[Rusty1103]

Well if ypuve got a new engine i would Strip the .15 down so you have got spare bearings and pull starter just incase you are out on the field and something breaks it is an easy fix/bodge job until proper parts fit

[shiftypowers]

yeah true thanks for your help dude

[Rusty1103]

No problem
