I just installed a Jet Silver 80 cc engine on an old 26" Schwinn Collegiate and it runs great. What is the spark plug gap supposed to be set to?
It's marked "GNT" and "made in China E6T"

Thanks!

Why mess with it if its running GREAT ?
0.4mm-0.5mm or .028-.034 inch.
If it get starting hard might close it up to .020
Good Luck.
 
Yeah, I keep relearning the old adage: "...if it ain't broke, don't fix it!". But I'm always trying to improve things -- my downfall!

Thanks for the info!

NGK BP6HS is defo a good investment for $2 lol, I showed the stock, kit-supplied "spark plug" to some Yamaha performance techs for a good laugh...

They didn't think it funny o_O

They seem to take life a bit too seriously lol :D
 
I use any old piece of .031" safety wire as a gapper.

And notice no difference at all between BP6HS and cheapo GNT in terms of performance or reliability. On average they both last a couple years with 50:1. Much shorter time with oilier mixes.
 
Not gonna take the bait - the ol' "what brand plug" debate knows only casualties lol

Yes, ofc the 20 cent el'cheapo plug is just as good as the renowned NGK :p
 
I've seen plenty of manufacturing defects in those chinese plugs!!! Like oil coming out of the plug itself (from leaks in the plug) & the electrode tip falling out!
 
We gap ours to 30. It seems to be just right for all around performance.

20 cent? 20 cent? Did somebody say 20 cent? Where? 20 cent? :)

Even though they are both made in china now I'm sure the brand names have better QC. I have been very lucky to never have a problem with the cheapies. But I still replace with NGK/Denso/etc simply because they are available local and, believe it or not, cost less.
 
2 dolla- 2 dolla! :D

Now I have that stuck in my head... thx xlite o.O

BTW - the reason I'm so "sold" on the NGKs is cause of all the assorted engines in various stated of disrepair I've had o'er the years with NGKs in them, the NGKs simply wouldn't foul... I'm not usually big on touting some marvel product or another, but seriously - I love me them NGKs, I wouldn't have dared run anythin' else in my 2stroke ultralight and that's a fact.

Not any multi-pronged, uberfancy, over engineered techno widget btw, just the good 'ol singles ;)
