    Discovered a fuel leak here when I filled it and tipped boat back. Think this might affect fuel delivery?

    Doing another timing test, it may have come lose. Pulled plugs and this is what it looks like!!! I put in a can of sea foam…. Never seen caked on crap like this before. bottom was clean tho.

    1990 Force L-Drive 90hp -- Can't get it to idle -- losing my mind :D

    Flywheel key is solid. everything on the boat is to spec, as best as I can do it. Fuel delivery is good (pressure at the carbs (3 - 6 psi) * yes Fuel pump is not leaking internally *. No Carbs cleaned and float level correct. * yes Carb linkages set properly * yes Cam set properly. * yes...

    I have no helper :( I’m gonna go put 91 in it, you think that could be some of the problem? man I’m doing the best to do this logically please stop with the negative blows. carbs fixed with proper link and sync. Timing is 28 btdc at static with wot in gear. boat is not waterlogged.

    I also had a 1929 prop that produced the same result, also another that didn’t improve speed

    Going to fill Woth 91 octane and try it again, will have working tach this time. Electric choke solenoid I’m working order, it’s for sure open choke in the video above working correctly, all butterflies are link synced to spec. Im running this for a prop, brand new not spun: Qiclear Marine...

    Hey, actually my floats were super outa whack. It was causing sputtering and sneezing -- I think the bottom carb had a slow flood. It's PERFECT now!

    Yes on spark, timing gun flashing nice and solid on each one. Wonder if my plugs are toast, been 4 months torture on them now.

    Floats were way off, fixed that, installed new bellow. engine no longer stutters, sneezes, or randomly shuts off — smoooooth. Had to slightly adjust air mixture, but still no actual improvement. Still only getting 7mph.

    I’m using logic here dude, but I understand your comment. It’s gota be floats are closed to early. Gota be. Or I have bad compression but that was tested recently. And I KNOW I adjusted the floats to be even, which may be too low.

    1990 Force L-Drive 90hp -- Can't get it to idle -- losing my mind :D

    Yeah I hear ya, maybe one of the floats is right screwed. Will report back over the weekend when I takem' apart.... for the 4th time.

    For future reference if any one wants the measurements, look at step 8/10

    1990 Force L-Drive 90hp -- Can't get it to idle -- losing my mind :D

    I got this timing light because it had tach built into it, but yeah I just leave it at 'zero' degrees to check stuff. Maybe I'll pull the carbs off again and check the high jets, double check the float bowls, maybe I've adjusted them incorrectly and it's starving out at high load? I did adjust...

    Hey, I'm also using Octane 87, I can get either 91 or even 94 -- will try when this tank runs outa gas... I have replaced the Anti Siphon valve and rebuilt the fuel pump diaphragm, checked for debris, and carbs are rebuilt. Could it be float bowl adjustments?

    I understand the concept of power -- I'm asking what I should do to increase power under load..

    Hey all just got back from water, boat DRIVES at 3500 rpm maybe boat can REV way higher at 7000 rpm what… does this mean? Added two new videos for review. Video 1 is at dock in idle revving, WAY higher than under load. I'm very certain the timing, link sync, carb air mixtures are correct. If...
