Well shes gettin real close. My cheapo used mounts came today so i set onto more progress. Bolted er down only to find out you can put the pipe on later
Anyways i fiddled around and used some of the shims it came with to get the engine into what seemed a low stress position. Fiddled with fuel lines etc untill it seemed they were right. Coolant lines all hooked up except the second "duel Cool" fitting on the head which is my only snag right now. Could i Tee the line into the tell tail fitting or should i just plug it. If its simple to hook up i'll run it. Otherwise i gotta go buy a plug for the hole.
Heres some pics showing just what a POS it is but for free im satisfied sofar. Pluss if it turns out to be a reliable rig i might just take it to the body shop i work at and give it a new look.

PLEASE LET ME KNOW IF SOMETHING LOOKS WRONG!!!! im a newb

Ok, I went down this morning poured some gas down the carb and it fired right up but died as to be expected. I primed the fuel line to the carb with a squeeze bulb but it still wont go. I had two carbs. One with a square pump and one round which i used. So playing with the hoses this is what i understand:
Line from filter out to side of fuel pump
Line from left side of carb to vacume valve.
Small line from vacume valve to reference port on venturi bore.
Pulse line to barb in the middle of pump cover.

The pump only seems to operate when the return line port is pluged so does this mean that during running that the vacume valve closes??
If so perhaps my vacume valve is bad.

put the sqare pump in

look at the arrows on the pump

The square pump carb is half together and looks terrible inside. The throttle shaft on it turns hard too.
I picked up a new mukuni kit for the round pump carb for fear the other carb could be junk. After getting water hooked and running it on the primer for 5 min or so i think a carb kit is all it needs. I figured out that thing i was lookin at was a rev limiter. someone told me the mariner plate on the bottom is suposed to be an upgrade or some crap so that cool i guess.

Ok so i rebuilt the carb today. and still no go.
I followed the diagram super close and it still wont pump fuel. I thought mabye for some reason the engine crank seals might no have sealed right so i started pulsing with my mouth on a tube. I can blow in and through slightly into the return line through the pulse port. Sucking is sealed. This is exactly what it did before i rebuilt it. pulsing in and out with my mouth quickly I can see the fuel in the inlet line just move back and forth. Sucking or blowing constant does not move the fuel so i know its not leaking air into the fuel inlet line.
Is there anything helpful to know??
Its almost like a check flap in the carb isnt sealing. All the non wearable carb parts looked good. No scratches etc to cause a check valve leak.

there is a check valve on the tank

yeah i see the valve but its not inline with the fuel lines. Looks like a vent or something going up into the front of the ski. Should there be a valve inline with the return?
