hi All,

I'm completely new here :-) and am just getting in to RC'ing
I bought an old RC which I hadn't used for a while, and finally got round to sorting it out recently. I stripped down the carb. because there was so much crap in it from lying around so long. Anyway, its all shiney and clean now :-) but I have a problem. When I have the needle completely closed, and blow down the fuel line, I get fuel going in to the carb. Thats not right is it?. When the needle is all the way in, it shouldn't allow fuel to get in to the carb. should it?.

The carb. is on a .15 engine and it does have 2 needle adjustments if that helps. Just I just thought I'd ask on here as to why the primary needle still allows fuel in, even if its completely closed !.

Thanks for any help in advance :-)

Even if they're completely closed, they're bound to let a little fuel in. As long as it's not flowing as if the needle was opened completely, you should be alright.
 
I think that's the problem... it does seem to let too much fuel in. What could be causing this? any ideas?.

Thanks
 
Possibly a deformed needle seat. I would try to get the engine running and see what it does.
 
The carburetor is never completely closed. By blowing into the line you are pressurizing the system, sending fuel to the engine, since the carb is naturally in the idle position.
 
Thanks guys for all your help. :-). I've managed to get the engine working :)

Thanks again
