FIXED IT. I used the pullstart assembly from the 8 port and parts from my .21bb and managed to get the roto-start fitted to the 8 port. After I was pleased to see that it was a success I ran into the issue of it being a 1/2 inch longer and not fitting back into the chassis so I ground away on the chassis until it made it in. Either way your screwed with these things. Your gonna f**k up oneways or pullstarts. I chose the rotostart way for conveinace and the oneways are about $7 cheaper than a new pullstart. Until its broke in I'll just back the glow plug off alittle whem I start it.
