I tried finding the answer here but hadn't yet. Please bear with me. Trying to check and play with timing because my engine just isn't happy and its a long story. Timing should be 10* BTC correct then all in around 2500 rpms which should be 34*, correct? Im partly confused because my balancer is marked 10 ATC to 0 then 30 BTC. Somebody marked 0 and 10. At idle probably 750 ish, If Im reading the marks and light correct, timing is about 18* BTC. I hadn't yet checked timing at 2500 rpm but will report back shortly. And #1 cylinder is the front cylinder starboard side towards the pulley correct?

I just timed my engine with zach's help and that all sounds correct except the 2500. I think 3500 is total advance and that's where you're looking for 32-34 advanced. Mine started at 10 idle / 25 full advance. I turned clockwise to advance and wound up at 18 idle / 32 full and she runs like a Swiss watch.
The balances only go up to 30 and I guess there's a special type of gun you can buy to project higher than 30 settings. I just eyeballed 32.
I'm amateur at best so someone that knows a lot more than me can confirm.

Oh, yes the #1 cylinder is the Starboard forward.

Well I set it to 10, dropped it in the water. Ran great in all sort of conditions. 0-48 a few times with lots of 25 mph too. After 10 minutes a slowed for the canal and it flooded out. Now I'm floating across the lake waiting for it to dry out.

Oh no.
When you say you set it to 10, does that mean 10 degrees at idle?

Yeah 10 at idle. For the few minutes it ran it seemed better there. All summer I suspected the carb to be flooding but never caught it other than a few hard starts 3 minutes after shut down. When it straight up stalled today I looked in the throat of carb and the secondaries had a steady stream pouring out.

That's a problem. Looks like you need a carb kit. That happened to me last year.
HUGE HEADS UP----- I went through 4 combinations of needles and seats before I found a set that sealed properly (assuming it's a Holly).
Cut a can in half and put it below the secondary bowl before putting the bolts out. Otherwise you get a half cup of fuel on uour engine. I found that out the hard way.
