Sparkplug gap
SOURCE: what is gap on sparkplug on 1978 Yamaha 250 snowmobile?
Hi nana
Leaving the plug set to what it came as is as good as set correctly, unless you have dropped the plug already:). Attempts to adjust the gap are often done wrong, and potentially damage the plug. Unless you are race prepping the engine/indexing it also, it will be fine straight out of the box. Good likely hood that the old 2stroker will need a new plug long before the gap becomes and issue:) Hope this helps.

SOURCE: I need the Gap settings
the sparkplugs are shipped with the propper gap setting *DO NOT CHANGE IT"
if its been altered, place a penny in the gap, and thats the space it should be gapped.
