kickasskev Posted March 19, 2011 Share Posted March 19, 2011 Does this sound ok for a running engine, it seems to speed up more when im closing the throttle. It makes the audio look out of sync with the video Only had this out once before about 4 months and it ended up being a runaway, dont what this to happen again, I have a fail safe now but that wont work if the engine speeds up when in the idle position It starts ok but then stall's on idle after about 15-30 seconds Quote Link to comment Share on other sites More sharing options...
bodgemonkey Posted March 19, 2011 Share Posted March 19, 2011 take off the air filter, is the gap in the carb about 1-2mm? Quote Link to comment Share on other sites More sharing options...

chrisknights Posted March 19, 2011 Share Posted March 19, 2011 just make sure your batterys are fully charged and if worrie do the old rubber band trick Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted March 19, 2011 Share Posted March 19, 2011 Also...in the vid, it looked very smokey and didn't sound like it was running well. Could be runnign rich and only when you closed the throttle and cut the fuel supply did it rev up. Did you warm up the motor first? Hard to diagnose a problem if hte motor is cold and spluttering. You may be getting a build up of fuel in teh crankcases that a good run will clear too. Quote Link to comment Share on other sites More sharing options...
kickasskev Posted March 20, 2011 Author Share Posted March 20, 2011 Ok people so ive had it to the field, it seems and looks very very rich, I have played around with the LSN but it doesn't seem to do any thing really, when I accelarate it bogs and dies, should I be adjusting the HSN???? Sorry for poor video Recorded by my 8yr son Quote Link to comment Share on other sites More sharing options...

kickasskev Posted March 20, 2011 Author Share Posted March 20, 2011 too lean low end too rich top end as simple as that? Quote Link to comment Share on other sites More sharing options...
8560ardvark Posted March 20, 2011 Share Posted March 20, 2011 as simple as that? pretty much yea haha, it is rising on idle which is a telltale sign of being too lean on the bottom end as it is revving higher to get more fuel and the top end.....is just bogging, not a problem, just needs a top end tune Quote Link to comment Share on other sites More sharing options...

henzy190 Posted March 20, 2011 Share Posted March 20, 2011 the filter is off on the video don't do that you'll get pieces of dirt flying round your cylinders at 35,000 rpm, not a good idea Quote Link to comment Share on other sites More sharing options...
Highlander Posted March 20, 2011 Share Posted March 20, 2011 (edited) NEVER run a nitro with no filter thats asking for tuning problems and a knackered engine Edited March 20, 2011 by Ibanez81 Quote Link to comment Share on other sites More sharing options...
kickasskev Posted March 20, 2011 Author Share Posted March 20, 2011 NEVER run a nitro with no filter thats asking for tuning problems and a knackered engine Only had it like that because my car wont prime fuel through when I cover the exhaust, I have to put my finger over the air filter hole and open full throttle and turn the engine over to get fuel to the carb/engine, is this normal???? my little car only needs finger over the exhaust to prime.

kickasskev Posted March 21, 2011 Author Share Posted March 21, 2011 thats not normal, is the exhaust system or engine leaking? that probably explains the bad tuning No mate can't see any leaks any where, it's seems untunable, was told to richen the LSN and Lean the HSP but this din't work, nearly had the HSP needle all the way in, and it was still smoking like mad when throttle was applied, also when just leaving it to idle it will eventually speed up and scream like mad, All parts of the engine are sealed with engine sealer apart from the roto start, should there be any type of gasket or seal to go in between the back plate and roto/pull start???? I also bought a new carb as I thought the old one was knacked but obviously not. Quote Link to comment Share on other sites More sharing options...

chrisknights Posted March 21, 2011 Share Posted March 21, 2011 Turn your idle screw down abit , and put your filter on when you run it , rich your LSN 1/8 of a turn and drive up the field and back to clear the build up of fuel a few time and get the car warm you have loads of smoke thats good need to see your car go up and down the field a few times when its warm as sorry mate video was to short to tell Quote Link to comment Share on other sites More sharing options...
