[QUOTE="CedarRiverScooter, post: 380752, member: 15465"] Update - Tested the prototype spoon today, no good. Cavitates worse than before. I peeled off 2 of the 3 layers of plywood & not much improvement. Ranchero, I am sure you are right about the abrupt transitions. It is not easy to feather it in with the glue-on approach I used. If I had a Phd in hydrodynamics I would know the exact shape to cast in fiberglass, but the trial & error approach could be time consuming. My new grate will be here next week, got my fingers crossed that it works. In the meantime, I think I will need to change pop-off springs in the carbs. Not getting anywhere close to running right. I think I need to have the impeller repitched too. Got to do some bat-turns today, woohoo! It's going to be a blast once I work out the bugs. [/QUOTE]
