Came back for an update, boat sat for a while when it couldn't be worked on. i replaced all carb hoses, took it out and it seems as if I've found something. Idles great and gets up on plane great it just has a small 1-3 second hiccup right at that 1800 rpm mark still. I'm not going to quit until...
Prop pitch I’m not 100% sure on. It came off of the exact boat that it is on now, a nitro fish and ski hull 18.5 ft. First 15 times out it performed great so I’m not sure if that’s something that would happen all of a sudden. I have a Z shaped hose running to the bottom of the block, then out...
Chris , doubled checked timing and made sure carbs were synced correctly. Just took it out and same deal. Not much left on this darn thing. I'm going to go over everything once again later today and if I have time, I'll try to get it back to the lake to get a video. Might give a better idea. PS...
Adjusted mixture a bit to no avail. Went as far as richening up all until motor died and slowly coming back in with all until i had a decent idle again. Nothing improved. Played with them a bit more but to no avail. As far as the reeds go i have no idea. I repowered with this motor a few months...
It affects the top two port cylinders, so potentially two carbs, but only one barrel each.
So finally got back around to working on the boat. After going through everything again I noticed I wired one switch box incorrectly so firing order was off. This was why I had the 2 black plugs . It...
Compression test last night showed all cylinders between 120-122.. using an spark tester during idle all coils were firing and open air tester showed plugs sparking good
So the boat has been at the mechanic for a few weeks for loss of power at 1800 rpm and a bad idle. Found chipped reeds, replaced with Carson reeds and added spacer plate. Idles fine now on muffs and in tank but once on the water it still doesn’t want to go after being in gear. All electrical has...
Over the weekend boat ran great all day on the water. Started it to bring it back to the launch and it wouldn’t run past 1800 rpm. If it happened to feather over 2k it would run great again up to 5500 rpm. Tested compression all are 115-120, getting good spark , all fuel system has been replaced...
