Hey y'all so I just got done rebuilding the top end on my 94 RM 125 started on the second kick with no problems. I wanted to start breaking it in and go through the heat cycles so I took it for a ride giving it variable throttle (on the first ride I did nothing more than 1/4 to 1/2 throttle. I noticed there was not that much power and when I stopped I noticed my air/fuel mixture screw was no longer there. I already ordered a new one but my question is, if it is possible I messed anything up by riding the bike with now screw? I'm asking this because now it will currently not start. Any input would be great. Thank you
