hi guys i no i seem a bit crazy getting such a decent engine for my first but its not as bad i made it out to be
i have learned this much..
that on first start up richen it (high speed needle outwards) and do not over rev it shut it down after 3-4 mins and make sure the piston is not at the top of the linner and let it cool to let the metals settle do this again up to 3 times
after i have done this put it on the track (still rich loads of blue smoke) and drive it with low rpm just blipping the throttle as not to over rev or stress the engine for 5-6 tanks allowing the engine to cool between tanks (keeping the piston at the bottom of the linner)
how am i doing so far?
after thats all done begin to lean it (high speed needle inwards) one full turn till i get the revs were i want them then richen it by 1/4 of a turn (outwards) then run for another 1-2 tanks
right this is where i get lost
setting the low end screw.. once i have the above set do i not need to adjust it from here on in
the idle screw im not to worried about
thanks lads but there is no hobbie shops that are set just for nitro racing and my club has a handfull of members who would know what they are talking about and not many non race days and with me not working at the minute and have to learn somehow im willing to have a go myself i have all the time in the world at the moment
anthony ling the engine is very tight so use a hairdryer as you said and i will change the rod as soon as it is broke in as ur advise
any more info or advise is welcome i wont be doing it till i get as much knowlage as i can
