    Ok i know y'all hate when i do a new feed but i needed to start fresh.

    I got the New Mag piston in and have all the value covers on, exhaust manifold, water manifold which i think 78lbs if torque is alot for them lil bolts i was afraid i was going to strip a bold. i think im ready to do a leak down test. any info please

    after the leak down test and say it comes out good now time to put the carb and everything back on to run a compression test. any info please

    ready to fuel up. im running premix but since i put a new piston i need to break it in right? so what fuel to oil ratio do i need to run now? before i was running 31:1 and what size fuel lines do i use again? just want to be sure i start fresh. any info please

    now for the the 33ohm resistor for the oil. how the heck do i do this? is there any pics or videos to show how to do this. PLEASE any info on this will help

    and finally wanna thank eveyone that has been helping me with the piston rebuild i went from not knowing a darn thing about this jet ski, to now i can do with with my eyes closed lol just kidding but i have learned alot so thanks guys but can you please help me get the finishing touches on this jet ski so i can get it back on the water and get the ole lady off my back lol

    Hey man, your comment on 78 lbs for water bar bolts, that is infact to high, if you did ft lbs i believe that torque is 78 INCH pounds I do my first tank at 50:1 to do a compression test, remove all the spark plugs put on the gauge, hold throttle WIDE OPEN and crank.

    I think he is running premix. If premix, run 40:1. Oil injected mix it at 50:1

    Torque is in inch pounds, not foot pounds. Either pick yourself up a torque wrench designed for inch pounds or divide by 12 to get foot pounds. Some members simply "tighten" those bolts. Fuel line as mentioned is 1/4" id. I run 32:1 for break in on the oil, with regular running at 40:1. Ditch the resistor and simply disconnect the oil sender lines inside the ebox. The display will simply read empty without a sender connected. IF you leave it connected, you need to zip tie the float in the full position.

    I don't see anything in your post about a restrictor, but, yes you will need it installed.
