i took my volcano sv out yesterday, first full tank great bashin in the dirt and all of a sudden it shut off i let cool for awhile and try to turn it back on, it wont turn on. =(


1. it wont start. ( over heat) ?
2. on of the wheel seem to be boggle, like its not spinnin right, maybe cus the dob bone? i think one of the dogbone is bent.


but now im really worry if my engine is over or not, can you guys help me out here.

you putting your engine at bottom dead center after you run it?....alot of things could cause it to stop running..overheating the engine, something breaking, loss of fuel or the glow plug to go out...

can you rotate your engine by turning the flywheel?...does it turn free or does it have spots it turns hard?.....have you removed your glow plug and checked to make sure it is good?/

most likely your wheel bogglein is due to a broken wheel

yea i took out the glow pug and try to pull it, it still sounds normal like nothin is wrong.
"you putting your engine at bottom dead center after you run it?." ? i dont understand what you mean. =/


the wheel just seem like the the spin right with all the other tires, when i full throatle it it seems to want to spin out of place, kinda scares me ahha =)

umm ok....basically you have your piston and piston sleeve....the sleevegradually gets smaller as it goes to the top...this is the"pinch" ...this gives your engine compression....as your engine heats up the sleeve expands at a much greater rate then the piston...this is why its important to get your engine to above operating temps asap (over 200 F.) this keeps your engine from wearing prematurly (yes running to rich will destroy an engine just as fast as running it to lean)....

what putting your engine at bottom dead center means is you put the piston at the bottom of its stroke (as far down the sleeve as it can go)..by doing this it helps preserve the "pinch" of your sleeve...if your engine starts cooling after its been running with the piston at the top of its stroke the sleeve dispinses heat faster then the piston which means it gets smaller faster,,,end result the piston that dosnt dispense heat as fast knocks the "pinch" out of the sleeve

a way to know your at bottom dead center is take out the glowplug, take a zip-tie and lightly stick it into the combustion chamber...rotate the engine using the flywheel until the piston goesall the way down...hold that point, flip the rc over and mark your flywheel with a permanant marker. (there is a hole in the chassis that allows you to see the flywheel)

man this sucks, i dont understand much, i might try to take it to the local shop.

but thank you for the advice man =)

I included a pic with a "cut" view of the interal engine parts. in this picture, the piston is currently at "TDC", known as top dead center. BDC, bottom dead center is when the piston is all the way to the bottom. When the piston is at the bottom of the stroke, you can mark your flywheel so you know where to turn it when setting it to BDC after running.

While you run your engine, the metals expand. You can lose your pinch at the top of the sleeve by leaving the piston at TDC or at mid stroke simply because the metal will retract as it cools. Each sleeve has a pinch, the pinch is tighter towards the top.

OMG thanks alot man..ill kkeep updates if i have more questions =)

just proof that sometimes a picture is worth a thousand words..lol
