Hi,
Just found this site,and I will tell a little about myself,before asking questions....
I have a Worldcat,with twin 2006, etec - 200 ho's,and I cannot find my model #'s anywhere,but have the serial #'s......05129931,and ,05130058
I live in the northeast(nj),where we have hot and cold weather,and I use from march to december...I run xd-100 oil.
I had plugs replaced (qc10pepb)at about 100 hrs,because of rough idle,and hard starting.
Just recently,had plugs(qc10wep) ,and deflector pins replaced,at about 230 hrs...I
I have had all updates,including deflector pins.
My question is,can I run qc12pep plugs?
Also the new qc10wep plug,I cannot find anywhere,and my dealer has had trouble getting them also.
I have read on here that an NGK plug is available,and did a search with those numbers(Part number 5007120),but come up with nothing,Any ideas?....
thanks,jeff
