Deafty Posted October 29, 2014 Share Posted October 29, 2014 +1 very common question ad answer is 9/10 the .21 people say the .28 is hard to tune, and or don't hold a tune well. Quote Link to comment Share on other sites More sharing options...
shdaxner Posted October 29, 2014 Share Posted October 29, 2014 I found my Hyper ST (which was fitted with the 28 engine) to be much easier to tune than my previous nitro car, a HPI Trophy buggy with 21 engine. My money would go on the ST everytime, much better all rounder and very capable car. Quote Link to comment Share on other sites More sharing options...

jony nitro Posted October 29, 2014 Share Posted October 29, 2014 When I ran nitro a while ago had major timing issues was PITA had a 21 engine can't remember how many ports it had but was better, and read many threads about the 28 as well. Plus I would post if I was mistaken Quote Link to comment Share on other sites More sharing options...
gouldypg Posted October 30, 2014 Share Posted October 30, 2014 (edited) I've just brought a .21 ss 2 weeks a go I'm well happy with it just wish i could find the needle settings, read 2 or 3 different settings on the Web some say turn lsn 3 and half from flush, but mine will fall out if I do that Edited October 30, 2014 by gouldypg Quote Link to comment Share on other sites More sharing options...
Anthoop Posted October 30, 2014 Share Posted October 30, 2014 I've just brought a .21 ss 2 weeks a go I'm well happy with it just wish i could find the needle settings, read 2 or 3 different settings on the Web some say turn lsn 3 and half from flush, but mine will fall out if I do that The LSN should not be falling out with three turns from flush....it will take around 10 turns from flush for it to be fully released from the thread on the carb. I just tried... The LSN is the black screw where the throttle servo connects to the engine...opposite that and at a slight angle is another black screw, that is the idle screw.. The idle screw will be well below flush if you set the throttle gap to 1mm.... Quote Link to comment Share on other sites More sharing options...
