Fuel Delivery/ Carb Question

[B-Roy]

Well, I got this 94 stock750 sx for $400. Ive pulled the tank, cleaned it all out, replaced all the fuel lines, and added fresh gas/ coverted to premix.

The ski has been sitting for about 6 years.

Ive done everything, but pull the carb.

What the ski does is takes a lot of choke to start, and once it starts runs great for about 5-10 seconds, than just runs out of fuel.

I know this is a carb problem, and I am going to rebuild it, but I was wondering more specifically, what part of the carb sucks gas into the carb, and keeps the flow coming in after the motor is started.

Also I coverted to premix, but I havent installed the plate yet. I was wondering how much of an affect not having the small rubber cap, where the oil line connected to the intake manifold. (I imagine not much, but was just curious)

Thanks, Brian

You will get an air leak if not capped.

Im going to install it as soon as the kit gets here, but in the mean time, its not throwing me up much on fuel delivery is it?

Tear the carb apart and clean it, rebuild kits are seldom needed, only a couple of parts go bad very often. But by all means take out the little filter in the inlet and clean it. After six years, guessing it's varnished up so bad it won't flow. Next time you buy a ski, clean the carb first thing, not last...

Will do, Brappp

I just didnt clean it, because Ive been doing other stuff. I planned on it. Here in MI we have another two months plus!

Yeah, don't ever run your engine with the hole in the intake manifold. It just invites seizure..... Prof
