Newbie - cannot start nitro buggy

[HATZY]

replace the fuel line. if its alot of air then it can give the same effects as an air leak (it is an airleak, just in a different part of the fuel delivery system)

[don shaleone]

I swapped the lines over with my other one and was the same, so I swapped the nozzle that goes round the hsn with my other one, that improved it and didn't really leak after that but still will start I just can't keep it still.

I thought it might be the clutch stuck but its fine, if I lower the idle it just cuts out and is hard to start.

I did have it at one point where the wheels spouted spinning but then started again straight away, it was kind of jerking on and off the clutch....

Any ideas its annoying me like hell, I've got the engine off atm, any easy checks I could do?

[don shaleone]

What about if I swap the carb over from my other car as I know that is set to idle properly?

[HATZY]

it may be set right on the other engine but it will more than likely be way off on this engine. have you driven the car yet? if you have, whats it like when you accellerate?

[don shaleone]

Nope I ain't took it out, tried swapping carb an it acted the same.

I think maybe the clutch spring is a bit loose its a 2 peice but I can move a peice easily with no effort but it pulls back in.

Any thing I could try?

[HATZY]

if its a 1 piece spring you can chop a loop or 2 off but first. make sure everything on th engine is nice and tight, backplate, head etc. you can richen up the lsn a little to lower the idle speed but the clutch should be stiff, you shouldnt be able to wobble it. have a look at the holes in the clutch shoes to see if they are distorted in anyway. if the idle speed is too high and sat idleing too long the clutch will get hot and soft which will allow the pins in the flywheel to stretch the holes in the shoes

[don shaleone]

Yeah will have to try the lsn.

The actual spring is just a type of rubber band...

What is the back plate?

[HATZY]

the backplate is what the pullstart screw onto

i could be wrong but ive never heard of a rubber band bein used :S

Hmmm might take it to the local model shop and see what they think then

[bodgemonkey]

Sounds like that is a bodged up clutch if it has a rubber band mate. Best bet is to upgrade to a 3 shoe clutch anyways

[don shaleone]

Yeah that's what I was think it was bodged up, how much do clutchs set you back just from a model shop?

[don shaleone]

Here is a pic of my clutch

So I would need the fly wheel aswel as a clutch if I were to get a 3 piece....

Can someone send me a link as to what I should be looking for please

[HATZY]

the way shose shoes are facin, they would have more grip on the inside of the bell, with that o-ring holdin it together you would stand no chance of gettin the wheels to stop spinnin. if you dont want to go 3 shoe i found an alloy clutch and spring set on ebay. i'll get the link later if you want it

[don shaleone]

So it looks pretty certain that would be the prob then?

If you could give me the link then mate thanks

the clutch shoes on yours look almost new

[don shaleone]

Sorted a clutch today, I think it idles okay now but the clutch bell gear and the big gear keep jamming up.

I thought it was the alignment of the engine but then I noticed the big gears teeth are loose and can move forward away from the mesh of the clutch bell gear. Surely that's not normal....? Do I need a new one?

[HATZY]

have a look at the center diff make sure its all tight. it could just be loose

[don shaleone]

Yeah was loose all the screws came undone, just putting it all back together now.

I actually got to drive it for a short while before it locked up, hopefully now when I put it back together it should be done :@

[don shaleone]

Keeps flooding now :s

[HATZY]

glow plug and starter ok? take the plug out and stick it in the starter

[don shaleone]

:@ taking ages to glow and when it does the glow is weak, need a new plug already?

[HATZY]

give the glow start a charge first. is it the only plug you have? if you have any others, try it in the glow start

Edited January 9, 2012 by HATZY

[don shaleone]

glow start is fully charged,I have another one which used to work but was weak, that one dont work either

Is there anywhere I can get a small bundle slightly cheaper than just one at a time from a shop?

[HATZY]

ebay would probs be your best bet

[don shaleone]

yeah I thought it would be.

When I pull off it nearly stalls/or does, does that mean I have to make it lean or richer?
