At wavedaze a few years ago, some dudes had a jammer with the 500 engine in it. They decided to zip tie the throttle wide open and see how long iy would run before it grenaded it melted down. Sucker ran for 15 min wide open out of the water before it shut down. After about 11 minutes it started...
The stock jetting for 38s on a 62t is 70 pilots, 130 mains, 1.5 n/s, 115g spring. I believe the popoff is around 55psi. Since you have the open style flame arrestors you'll need to lower the popoff. I believe just replacing the spring with a 95g (reverse wound) would get you close. If you have...
ive never ridden a eme hull before. did have a friend that bought a eme q8 for a short time. it ran a kawi driveline. everything was designed a little different on that ski. the handle pole bracket was basically bolted to the sides of the hull and the handle pole was between it. that i wasnt a...
i have found 25psi popoff with a 2.0 n/s 95g spring to be the sweet spot at least for me on popoff. this is with 44s or 46s and using a 61x style flame arrestor with 1 screen. then ill adjust jetting accordingly. at 25psi, i can get excellent throttle response and no fuel dribble. i prefer to...
Assuming those are oem 760 sbn 44s. This should be a starting point for you that should get you close.
2.0 n/s
95g spring @25psi popoff (assuming stock flame arrestor with 1 screen)
115-125 pilot
120-130 main
1 turn out both adjustment screws
Again this is a starting point. I'd start with 125...
Stock carbs are designed for stock engines. Sure they'll work decent on a modified engine, but you're leaving lots of power there. You have to pick one: horsepower or fuel economy.
Op already has dual 46s available, so why not run them?
I have basically the same setup you're wanting to build with the exception that I'm running dual 44s instead of 46s. If I did it again, I'd go with 46s for the reason of not having to go bigger if I went bigger on the engine. I've seen 48 full specs on 701s before so dual 46s will be good...
You couldnt pay me enough to ride a Bob hull personally. Between the Bob and the krash, I'd go with the krash all day but as others said, there's much better options out there. No hull is completely perfect in every regard, they all have pros and cons. Personally, for ride quality and looks...
I noticed on the hsi adapter that goes on the nozzle. You have the cable bolted to the outer most hole. This will reduce the total throw. To increase throw, move the cable to the inner most hole on the nozzle and the outer most hole on the steering plate to achieve max throw.
The 08+ cable...
Check the one way valve in the tank. Make sure air can go through but not the other way. If the one way valve isn't working properly it will cause fuel delivery issues.
When you do a leak down, spray the engine down with soapy water and look for air bubbles. If the engine has been sitting for a while before starting, it's possible to have air in the fuel line causing a temporary high idle. That will settle down after the lines and carbs are full of fuel again...
