Ok here's a few videos of the results of trying to tune my carb. The idling sounds ok to my ear but when you give it gas and let off it will still be giving it gas and revving really high you can see it in the second video if you watch the throttle/brake servo arm, also when I let off the brake it revs for a sec then goes to idle, any ideas on what this could be would be really helpful, I have been messing with it for awhile now and can't seem to figure it out.


PS. For some reason the piece the brake arm is connected to won't stay down and I lost that little rubber piece so I gotta find something or someway to get it to stop rattling.

I'm still a newbie but when I installed my 999 I had to adjust the stops and the springs on the throttle linkage. You might try that it's kinda like not having a throttle return spring.

Should I move the stoppage towards the servo or away from the servo?
