spark plugs come loose

[spurdy]

my elavation is at sea leval live on the coast.... would going to a like 18cc or 20cc dome cause a huge loss in power to fix the problem... running menthanol or alcohol isnt really option where live its kinda hard to get ahold of trien to avoid that.....

 

I wouldn't go to that big of a dome. I would start with a 17cc dome. That's what I was running with about 175 compression at 1000 ft.
