Adamobie1 Posted January 21, 2022 Share Posted January 21, 2022 Any advice with setting up idle gap, low and high end needles on the Hpi bullet 3.0? can’t start the thing! is it worth getting a preheat engine cover or starter box to help? any advice appreciated Quote Link to comment Share on other sites More sharing options...
Yorkshireman Posted January 22, 2022 Share Posted January 22, 2022 As a general rule for starting both high speed & low speed should be flush. Idle gap is 1mm ( l think )...should tell you in the manual. Also have a look on YouTube, there's a great video by JQRacing entitled "know your idle gap". Wouldn't bother with a heater myself.

froggy8 Posted January 22, 2022 Share Posted January 22, 2022 (edited) as above but always use an engine heater, it will prolong the life of the engine. less strain and less wear imo. Edited January 22, 2022 by froggy8 1 Quote Link to comment Share on other sites More sharing options...

Adamobie1 Posted January 22, 2022 Author Share Posted January 22, 2022 How about a root start or starter box, would they help get the engine running? pull cord is a nightmare or I’m doing something wrong 😑 Quote Link to comment Share on other sites More sharing options...
froggy8 Posted January 22, 2022 Share Posted January 22, 2022 i preferred the pull start as i never had any problems with it, al ways heat your engine before you try to pull start as when its cold, the piston will be tight, the engine heater helps loosen the piston slightly to make it easy to start. if you have messed about with your needles then its best to reset them all making sure when you screww them that they are both flushed with the outer ring. once you have done all that then it will be running rich, that is for breaking your engine in. when you have broken your engine in then its time to tune it by leaning the high and low needles but make sure your engine is up to temp before tuning. your idle gap should only be between 1mm and 2mm.
