have had an evenrude 100hp, #100999s for a while and has always run strong. Took it out and no holeshot. Would run about 47, now only about 35 and have to walk forward to plane off. Changed fuel pump and didn’t help, so did a semi-carb rebuild and new hull lines. Took it out today and can’t even get that. Seems to want to die on wot. Push choke in momentarily and it jumps. Opened tank to see if vent was clogged and didn’t help. Compression is good-130 on all 4. Starts easy, fun’s good at high idle. Plugs good. Any ideas would be appreciated. Scheduled to go in shop, but not for another month or so....

When was the last time you cleaned the carbs not just semi cleaned them. If you have mid range jets in them you can't clean them with spraying cleaner in the carb. Actually, you can't clean a carb by spraying anything in them.

When you use the choke and it picks up and runs, it's time to take the carbs off and clean them.
