So I’m working on a 3 cylinder 70hp 2 stroke that initially wouldn’t run. After a compression test and a spark test I verified it wasn’t getting fuel. Pulling carbs for a good cleaning showed clogged jets. Once reinstalled she fired right up on the hose. Fine tuned for a decent idle and then headed to the lake. Once in the water it fired immediately and idled ok but with a slight lean pop. Tried to adjust but with no success. Under throttle it will die about 1/2 throttle. The only way it’ll accept throttling is if I partially cover the center carb to enrichen the fuel. The intake velocity is very weak compared to the other 2 carbs. I plan to inspect the reeds. Question is what, if not reeds, will cause this? Compression shows 120 across the board. I’ve also noticed anaerobic sealer at the crankcase seam so I know it’s been apart. Obviously I’ll check for a vacuum leak there. Anything else I’m overlooking?
