If it backfired hard enough to pop out the carbs, then the reeds will have micro cracks in them from it. And when a metal reed breaks, it will go through the engine and either knock a hole in the block in the rod slot(best case scenario), OR it will destroy a piston and sleeve and could even push the sleeve through the head.

Fermanator, I already have the reed blocks off and cleaned. To my machinist practiced eye they look ok. There's about a .005 - .010 gap between the petals and the base on all of them, and that's what the book says is ok, but I've have already made the decision to replace them. I don't want to take this engine apart a second time, so am going to take my time and make sure the front end is all ok before I put the engine back in service. Good call about the 2 brass pick up tubes inside of the bowls.. I didn't know that OMC made different sizes...(although it doesn't surprise me). I'll make sure they are the same and if not I'll change them out. Do they pull out or are they screwed in? I've already cleaned all the servicable carbs and carefully pulled and ID'ed the idle, intermediate and high speed jets from the other two carbs so I can put them into the new bodies when they arrive. All passages have been cleaned and blown out with compressed air in all the bodies and the butterfly plates behind them. Anything else I should be looking out for? Thanks for all the help guys... most appreciated!!!
