Not all jets work and the ones that do are not strong.

Have you cleaned out the washer/screen at the water input?

Each bathtub has at least one air control on the tub that when opened lets air into the jets that produce the bubbles.
If you are experiencing too much pressure out of each jet, some of the jets if they are adjustable you can turn them down by rotating them left or right.
The other issue may be the water depth in the tub before you are turning it on. Make sure the water level is at least two inches or more above the highest jet.

I had the same issue after mine was installed. The line to the jet in the back was crimped a little and when the crimp was taken out, it works just fine. The line that was installed was a little to small and it did not have room to fully expand. You might check this out and I hope that it is the same as mine. Easy cheep fix buy just getting a little bigger line.

First make sure the compression is strong. Next ensure you are getting a strong blue spark at the plug. Make sure your fuel/oil mix isn't old; if it is drain and change it. If you have good compression and a strong spark, put some fuel/oil mix into a spray bottle and spray some directly into the carburetor throat. If it fires after spraying, the engine is starving for fuel. Make sure fuel flows freely from the petcock. If it does, odds are your carburetor needs attention; most likely at least a thorough cleaning to remove any gum/varnish that may have formed. Just be sure not to put steel ojects into any of the jet holes or you will end up enlarging them. Wood is OK and copper wire is OK; also be careful that whatever you use to clean the jet(s) doesn't break off into the jet.

Did you had someone install the jet kit and adjust the valves? If you did i would take it back to the shop.If you did it then you will have to troubleshoot it to fined the cause. Do a spark plug reading this will determine if the bike is running lean or rich.And yes it is possible to have the timing off. Hope this helps

If you don't have directonal eyeballs on your jet's you can get a dirveter for the jet that will push the water down the wall rather than out into the pool. Get these at your local pool store. Baracuda and Kreepy Krawlie both make them.

Sounds to me that you may have a blocked high pressure jet.

THERE IS ONLY ONE THING THAT WILL CUASE THIS, PLUGGED IDLE JETS AND PASSAGES. REMOVE THE CARB AGAIN AND SOAK THE CARB IN A STRONG CLEANER OVERNIGHT TO DISOLVE THE HARD WHITE RESIDUE THE BAD GAS LEAVES BEHIND, JUST RINSING AND BLOWING THEM OUT WILL NOT WORK IN MOST CASES.

check the fuel line first and filters this will cause the motor not to perform like it should.

next clean the carbs and the jets one bit of sand in a jet could be devestaing.

Pull the slide out and then move the clip on the jet needle one notch lower. Also try two notches to see which helps most. This will richen the mix in mid-range.

Pleas rate thia answer. Thanks v222407! :)
