Gents, I've just posted an updated Gas Weights link to a spreadsheet I've been building. It's elsewhere in the Gas Engines forum. The reason I wanted to post here is that Scott's 46cc is within 3 grams (less than the accuracy tolerance of my scales) of being the LIGHTEST 50 cc Class motor out there, period. My weights include mounts, plugs, ignitions, and real world mufflers. In the case of this beautiful 46 of Scott's, it is a Bisson Side Inverted muffler, going on a friends' GP Ultimate.

GORGEOUS, GORGEOUS work....
