dye29 Posted April 13, 2023 Share Posted April 13, 2023 Hi all i aquired a hyper 7 21 nitro buggy . As ive been goin through fixing some issues i put in some 20% fresh fuel and glow plug glows thats a T8 came with it so not sure if correct or not , i then put all needles back to factory setting H 2.5 out and L flush but its a nightmare to fire up then it runs but as soon as i remove glow starter she cuts out any ideas please . i blow through fuel pipe from exhaust side until i see fuel in carb then pull away .

Stormbringer Posted April 13, 2023 Share Posted April 13, 2023 It could be the glow plug thats on way out Quote Link to comment Share on other sites More sharing options...
locky Posted April 13, 2023 Share Posted April 13, 2023 (edited) I have a 21 3 port and I think your needle settings are out. The HSN looks too rich and your observations indicate same, so try leaning it. This says 3 full turns out from fully closed for HSN...https://www.cmldistribution.co.uk/diagrams/HoBao/Engines/HB_Engine_settings_Hyper_21 _3-Port.pdf Edited April 13, 2023 by locky Quote Link to comment Share on other sites More sharing options...

locky Posted April 14, 2023 Share Posted April 14, 2023 Factory settings are a guide and they will generally be rich so if it a used engine then lean the HSN. Let the engine warm up with wheels off the ground and rev it to higher rpms. If it runs ok then but stalls when on ground then check clutch shoes and springs and clutch bell bearings. A spare glow plug is always useful and required as they can fail and sometimes partially fail. Quote Link to comment Share on other sites More sharing options...
dye29 Posted April 14, 2023 Author Share Posted April 14, 2023 a strange on after reading loads of posts on factory settings ive put HSN to 4.5 turns out and LSN 3.5 turns out from flush and she starts and runs surely that's too much is it Quote Link to comment Share on other sites More sharing options...
Cactus Posted July 5, 2023 Share Posted July 5, 2023 If it conks out when you remove the starter the problem is the glow plug. Put a new one in. Quote Link to comment Share on other sites More sharing options...
