hello all i have 2 sunl 110s one runs fine the other i have had many problems with i have had them for a year and half. I stripped the thread out for spark plug. was thinking about just putting a 12mm plug in would that work?or should i use a thread insert? thanks to all that reply!

 

Hi. What size are the threads on the original plug?

I have machining experience and may be able to provide some in site that will help you make a decision.

I'm curios to know, have you been using a torque wrench, and how many ft/lbs are you using? This could help others to avoid this problem your having.

Edit; Please provide the numbering info on the spark plug its self.

Thanks, Buyingchina.

 

original plug is 10mm x 1.75 .500 reach drilling and tapping hole is no problem a thread insert or helicoil for a 10mm plug is same size and thread as a 12mm plug just wondering if a bigger plug would have less spark with stock ignition. i do not use a torqe wrench and dont have numbers right now im at work thanks

 

Hi. Looks like your asking more of an electrical question that I miss read.

Some one else will have to help you with that.

Thanks Buyingchina
