snchris1 Posted January 15, 2012 Share Posted January 15, 2012 replace it...under the compression it might not be strong enough...so get a new one in the engine and see if that works chris Quote Link to comment Share on other sites More sharing options...
HATZY Posted January 15, 2012 Share Posted January 15, 2012 it may look ok but under compression you have somewhere in the region of 22x more air in the combustion chamber at tdc than you do at bdc. i would say get a new plug anyway and give it a go again Quote Link to comment Share on other sites More sharing options...
Slacky Posted January 15, 2012 Author Share Posted January 15, 2012 Ok I'll pick one up. Is there any needles I need to turn to get it running in the mean time? Quote Link to comment Share on other sites More sharing options...
snchris1 Posted January 15, 2012 Share Posted January 15, 2012 no theres nothing you can do....so get the glow plug but make sure it the correct glow plug and it should work from there....then you just have to tune it chris Quote Link to comment Share on other sites More sharing options...
HATZY Posted January 15, 2012 Share Posted January 15, 2012 wind the hsn and lsn all the way in counting how many turns it takes to close then wind them back out to where they wher, thats to keep track of the needle positions but like i always say, no point tryin to tune the engine if the plug cant sustain it Quote Link to comment Share on other sites More sharing options...
