I recently replaced the rear pivot block on my Losi xxxnt-sport rtr and as part of the process removed the idle adj. screw in my carb (so I could move the rear diff. around) Now I put it all back together and it wont start. I reset my HI and LOW needle settings, checked glow plug, changed the fuel, made sure the car is warm etc... It doesn't even sound like it's close to starting.

Also my owners manuel has no detail on the carb. Is there just two pieces to the idle needle adj. (screw and spring)?

And how do you set it (idle adj.) When I pull the air filter I can see a silver piston like thing and an oval hole in it. where should the hole be when setting the needle. NOTE: if I screw my adj. needle in to far the silver thing will not move....that's why I'm thinking I'm missing a piece.

These are probably stupid questions but I have tried everything. Pleaes help.
