Losi Aftershock Problems

[Losi B-rad]

I recently bought a losi aftershock. It was fine to start with but then started to screw up. When i throttle and let go of the throttle it holds the throttle on but a bit lower than normal revs but higher than idle? How can i fix this?
Thanks

it sounds like it could be a tunning issue or and air leak, maybe a bad glow plug.

Check the throttle return spring and the throttle linkage for binding. Sealing the engine is also a good idea.

Yes I think it might be an air leak because it sometimes bogs. What do you mean by sealing the engine? Where could it be leaking from? When i pull the throttle it returns fine because i tried it when it was not running.

This is a good article and has a video on how to seal an engine:

Just sounds a little lean on lsn to me.

It looks like there is some liquid all over the spin starter. What could this be?
