Post Prodrive engine surge
Recently bought a 2006 35hp prodrive with 50 hours. Has cam, flattened pistons, stroker rods, roller rockers, titanium pushrods, and dual mikuni carbs. The motor sat in a garage without much use and runs fine but randomly when running WOT the motor will bog down and sound like its flooding. If I put it in neautral and rev it a little bit and then get back on a plane, it returns to running fine at WOT. Does this sound like a carb issue?

Sure it's possible it's a carb issue or fuel feeding issue, you got a pic of the twin carbs?

Sounds more like starving than flooding to me...

My guess is airleak or something going on in your fuel system..

I would check all connections, and make sure vented properly or vent is open.

What type of connections do you have and where?

In line filter? Type of tank? How connected? Inline bulb? all those are potential areas that you can have issues.....

ended up being the plastic liner inside the fuel line. Was falling apart from being old and blocking the lines. Thanks for the help
