You need to start at the simple stuff. Check the spark plugs and see if they are wet with gas. If not, could be a fuel pump issue. See if the plugs are fouled, change them and check for spark. If you have both, it should at least sputter. Check for water in the fuel.

Have you cleaned the carbs and fuel tank , checked the plugs and coil ht's and connections ?

sounds like the carbs need stripping and the jets etc unblocking ! does the throttle link return fully to the tickover position ? or possibly the crank seals have worn letting air in !

replace solenoid

NO ANTIFREEZE!!! simply hook up to the flush fitting and while running start spraying fogging oil thru intake . you want to "load" it up with that stuff and don't rev high for about 3 or 4 min the just disconnect battery and spray motor and pump down with WD-40

there are no gears just a direct drive from the crank to a jet pump ! if theres no propultion of water it could be several things ! 1. plastic bag etc in the intake to impellor pump assy ! 2. impellor gap to housing too much ie worn impellor ! 3. impellor not turning because splines on either the shaft or impellor worn ! 4. drive coupler damaged and spinning on shaft ! Try running on a hose pipe and look at rear of engine ( remove plastic cover so you can see the 2part coupler and drive shaft ) . Check the impellor assy !

There should be an adjustment screw that looks like a "t" on the side of each carb. Screw it in 1/8th turn at a time to lean it out. Too much and engine detonation. I would recommend getting the retrofit kit to block off the oil tank and run mix fuel. Then there are no issues with too lean/rich, oil pump failure, plugged oil filter, broken or collapsed oil lines etc. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/matthew_d24b835e574ef6ca
