ahhh. the memories, lol
ill cut down to the chase.
as some of you will remember, i had a million problems with my 1/8 truggy about a year ago and got it fixed.
i havnt touched it throughout this year for non-stop studying. I've finally pulled it out again and blown the dust off. the mill runs, yay! it moves, yay! but i can't seem to tune it right.
the glowplug is somewhat black-ish (very slightly) on the end. I'm assuming the HSN is a little rich. and when it accelerates slowly, I'm not 100% but i think theres a bit more smoke than expected. when it accels fast, it just goes 'cough...gasp... wheeze' like a 90yo grandma going for a 50mi marathon (i think it needs more fuel... desperate for air means it stutters right?). but it starts fantastic. and sometimes, if i manage to get to around half throttle, the thing instantly becomes too rich (i think a combo of both needles). temps are ~216F
and when i get accel right, as soon as i drop the throttle suddenly back to idle, theres some instant loading. and tinkering with usually doesn't go too well - usually to do with the accelerating HSN or LSN
i think the main problem is HSN is waaay too rich, need to bring that down. but temps are about right, no? or maybe i should get a hotter plug? or new fuel? (I've had this fuel since i was last here. but it was stored in a cool, dry, light-free environment throughout the year). i want to try everything tuning before i hit the shops.
since I'm a complete amateur at this stuff, ill leave it to you guys to tell me whats the problem instead of speculating
ps. any troubleshooting tuning vids out there? i can only find tuning vids, but not ts tuning vids
