97 seadoo challenger with replaced 787 carbed. I am putting this boat back together piece by piece and I've run into a problem I can't figure out with the oil injection pump.
1. Maybe relevant maybe not: I bought a used engine with verified good compression.
2. I have replaced (engine didn't come with) magneto, flywheels on both mag and pto, oil injection pump, carbs (used and not rebuilt), rave valves, rave rotary valve cover, and mag side cover. Basically, if it looked dodgy on the old motor I replaced it with a verified good OEM used part.
The problem: I cannot get the oil injector hash marks to line up. When I replaced the carbs I verified it was the right part #. The throttle cable has a ton of slack in it, but moves the carbs into the correct position when it does engage. The oil pump isn't even close to lining up no matter how i adjust the pump cable from the carbs. If I put a little pressure on the carb armature that is attached to throttle it moves a little additionally and I think I could line it up then, but I kind have to make it do it. I have set low/high speed on the carb to specs in the manual and based on what I have read in this forum. When I set the low/high I did notice that they were set at 1/2 turn out on high speed and 2 1/2 turns on low. I did not touch the idle adjust since I assume I would do it with the engine running. I am at a loss and could use any help you can offer.
