Hello fellows checking to see what gap are you setting your plugs at when spraying.

On motor I use tr 55 and gap them at .035

On 150 shoot what should I gap them at. I'm Using ngk 9 and ngk 10.
If I go up to 200 or 250 which way do gap go up or down.

I would run ngk BR7efs gapped @.030 on 150-175, BR8ef gapped @.028 for 200. The 9 may be a little cold for 250 depending on compression, your tuneup , timing , etc.

.030-.032, may want so consider a "BR" plug for the non projected tip, and may also want to go to a 6 or 7 heat range, especially for a 150 shot.

BR7EF running .030 is the business, running 175 shot with 6 deg timing pulled and stand alone fuel system of C16
