Last time I had it out it was. The motor is out of the ski now on my workbench. Was planning on tearing it down and looking in the bottom end to see if I can find something. I donno where else to look I've been over and over the fuel system and electrical system.

I just pressure tested the carb again and it's holding pressure with no leaks. I had a leak on the pop off pump connection the first time.

That's what I used, got lots of it at work. For my test I crimped a piece of tubing on the return side and might have made it too long and the pressure was slowly seeping by the restrictor. I was in a hurry to test before work, I will test it again tomorrow.

I checked around there with liquid leak detector and saw no bubbles.

I just pressure tested the slave carb with the mikuni pop off pump and on the gauge pressure isn't holding. It isn't leaking from the carb body or the needle seat. Where can the pressure be going? Ill have to investigate more tomorrow.

Ya its a double car garage thats detatched from the house. I framed it out, put a garage door in the back and poured cement behind the garage. I drywalled, ran all the electrical and built my bar in there. Used the garage floor epoxy on the bar and my workbench top. I now have 2 tool sheds...

Be careful if its on the edge like mine it will seize. Can you get the front cylinder to run rich? Mine was running great until it seized. I wont be happy until I can see the front cylinder real rich and then dial it back. I did get lazy with it and just ran it last time with the staggered...

My garage when I first redid it. Not as clean now.

Mine is setup for dual cooling with ADA head (185psi) dumping the front line without restriction. It never ran cool it was always pretty warm. I am starting to put valves on my skis and restricting water for cool water riding but when this happened it was middle of summer water temps were up...

@amitchell Did you ever find out what was going on? Ive been fighting a similar issue with one of my motors, no matter what I do I cannot get the front cylinder to run rich its always lean and I've seized it twice.

The head pipe is jacketed so pull out the water screw and its right there. The screw restricts water into the chamber you'll see when you pull it out. You will probably have to pull the pipe out to get to it. The hole is small, I used a small allen wrench and reemed it out.

I run the Mach 1 on a blaster. Pull out the water screws and check for plugging. Carbon will build up and plug off the small hole into the chamber. If its like my pipe there will be 2 adjuster screws.

I have the same pipe in a blaster and it mounts up to the ADA head with the bracket. The pipe has two mounting holes and only 1 lines up to the head. Take some pictures maybe you have something on wrong.

I run a Solas Concord YQ-CD 16/22 in my 1100 Yamaha B1 and it runs 57 at 6900 RPM. Hooks up great. Looks like your impeller is a small hub. The bigger hub would help you out, I think 16/23 big hub would be a good impeller for you.

Try the MTB ODIs I think they are a different compound than the watercraft ones. Sent from my Nexus 7 using Tapatalk

We did have to cut off a lot and it did not break. Still felt strong.

The stock bracket won't work unless you cut it up to clear the head. We did this on a friends ski with a Riva pipe that used the stock bracket.

Love that part of the river. Check out my avatar. :)
