Reply to "Empi HMPX carbs"

Good point, Mitch. Leaks, both intake and exhaust, and both rich and lean can cause pops and backfires. As well as normal warm-up, mine pops and burps a little until it's been driven a good 5 minutes and actually starts to warm up. I drive gently until it does so, and don't get those burps and pops.

And don't adjust your carbs unless the engine is HOT. Very important tip to follow here.

Exhaust flanges? Old school. V-clamps are the way to go for no leaks and no gaskets needed either.
