two possible reasons are that becuse your controller is reversed on the throttle input or your speed control is reversed

you can reverse the throttle on your controller or reset your speed control with the correct inputs

it's a .21 nitro engine.

starter box direction seams to be correct, the starter wheel spins the right way.

when it kicks over it appears to pause for a split second then changes direction.

i read somewhere that it could be over primed... this engine was given a good shot of afterrun oil before shipped to me.

also the plug was extremely wet and for the obvious reason of the engine running the wrong way i stopped it almost immediately

Looking at the crank, engine should be turning over CCW. Check your starter box rotation, seen a few setup to turn wrong way.

These 2 strokes will start backwards, never heard it blamed on too much aro though, but if crankcase is loaded, it may be causing probs. I'd pull plug, turn it upside down and pull PS or turn it over with starter and try to get as much as possible out. Then, try it again.

Don't think you're doing any damage - especially stopping it as soon as you can. Usually its a curiosity more than anything.

right-e-o. all done. drives nice and forward now.. the diffs were the wrong way around... i did try the search function, but it wasn't working for me so i had to make this post.

my next step is tuning.. if anyone can give me a quick insight to waht needles i have to turn.

starts straight away and i mean straight away. will idle fine, but on the grass with accelleration it conks out. i ran it with the glow plug attached and it seamed to be fine...

idle appears perfect as the engine builds up a few rpm before clutch engages.

do i need to adjust the low end needle.

thanks again.

advice #1 - you should have stayed with electric

advice #2 - do a search, a jog around the nitro threads to find nitro advice

advice #3 - refer back to your owners manual a reset all crab positions to their stock settings, and THEN ask questions while giving enough info for people to help diagnose your issues

advice #4 - start a new thread when you have a new question, otherwise you're threadjacking your own thread

advice #5 - see advice #1

Yup sounds like you need to adjust the low end, turn it clockwise, or in, about half a turn should work just about right

szakcajaru:dont tell people that they should of stayed with electric, itwas his choice to go to nitro.... and its about a million times more fun to run nitro

pinky: adjusting 1/2 a turn is a LOT. carbs should be adjust an hour at a time, not six. how about holding off on giving advice on things you know little about.

I was only joking about the "staying with electric" comment, and I think anyone about the age of 10 would recognize it. he had the word in his handle if you'd bothered paying attention

get off your back? leave you alone?

you're the one that started the childish argument by correcting me, and you are also the one sending me childish PMs telling me what to do.

if you really knew anything about gas cars you'd never suggest telling someone to adjust anything half a turn not knowing where they were at to begin with.

get a life
