skatedude25 Posted June 30, 2010 Share Posted June 30, 2010 (edited) Hi guys, I have a Hyper 7 TQ Sport Mach 28. When I apply the brakes in my buggy, the engine is being starved of fuel and stalls. It appears just a little force against the spring towards the carb starves the engine. I am learning to live with it by braking then blipping the gas when it is about to stall, but that is starting to get me down. I have tuned the linkages alot, I have even upgraded them this week to the following: http://www.modelspor...on&ItemID=28725. Is this normal? Should I be able to stall the engine if I hold the brakes? Or should I continue to play with the linkages? Thanks Paul Edited June 30, 2010 by skatedude25 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted June 30, 2010 Share Posted June 30, 2010 (edited) adjust the idle screw so it doesnt cut out whilst brakingits not the linkages at fault Edited June 30, 2010 by Stormbringer Quote Link to comment Share on other sites More sharing options...
Bridgey Posted June 30, 2010 Share Posted June 30, 2010 Have you turned the idle screw clockwise to prevent the carb closing too much? Quote Link to comment Share on other sites More sharing options...
msg Posted June 30, 2010 Share Posted June 30, 2010 Could be worth trying to put the idle up very slightly. There should be a 1mm gap that you can see when you take the air filter off, but you can have a touch more. It might be worth playing with the fuel mix a touch as well, if thats not right it could cause it to stall as well. Does it idle ok when its sitting stationery?

skatedude25 Posted June 30, 2010 Author Share Posted June 30, 2010 I havn't tuned the idle screw since purchase. Thanks for the tip, I will try that out tommorow night!! This forum is the best! Paul Quote Link to comment Share on other sites More sharing options...
skatedude25 Posted June 30, 2010 Author Share Posted June 30, 2010 (edited) Does it idle ok when its sitting stationery? Kind of, even when the buggy is stationary I sometimes need to blip the gas to stop it stalling. Edited June 30, 2010 by skatedude25 Quote Link to comment Share on other sites More sharing options...
Bridgey Posted June 30, 2010 Share Posted June 30, 2010 Ye, increase the idle mate, turn the screw clockwise, this will increase the gap and will stop the carb from closing, hence it wont stall. Quote Link to comment Share on other sites More sharing options...

If you still have bother, you might need to lean the fuel mix a touch, might be a bit too rich. Quote Link to comment Share on other sites More sharing options...

The Trooper Posted June 30, 2010 Share Posted June 30, 2010 check the throttle trim on your transmitter it should be at 0, if its not that could be the cause Quote Link to comment Share on other sites More sharing options...
