Ken Posted June 17, 2021 Report Posted June 17, 2021 For those that use the screw off plugs #4339 DCPR8E NAPA has them on sale where I live for $2.71 each. I have read some many options on the plug gap from .018 to .035 on various Rotax sites. What are the opinions here on a Rotax 912 100 HP 2006? Ken Quote
GrassStripFlyBoy Posted June 17, 2021 Report Posted June 17, 2021 Hi Ken, I had similar questions a while back, here's the trail: Plug Gap - Engine/Rotax - CT Flier Forum Quote
Ken Posted June 17, 2021 Author Report Posted June 17, 2021 Thanks I did read through that .024 seems to be the consensus. Although, Lockwood says .028. Quote
sandpiper Posted June 21, 2021 Report Posted June 21, 2021 I've used .025 for 14 years that I've owned my plane. Never a problem. Quote
