Motor hard to start

Dear all,

I have a correct craft ski naitique from 1990 pn whish I just complete a carb rebuild.
What is happening to me after this is that motor is hard to start from firts time.

I bet the feeling that too much fuel goes in the carb and starting gets hard. After manu try without placing any gaz, motor finally start, but caughting for a whilzna finaly get lauched.

When motor get a bit warmer,the no problem to start.

I have notice that during cold start, the electrical choke position is completely closed and when motor warmup, start to open.

Any idea why I get dificulties to start my motor when cold ? Could it be the choke position to be a little bit open ?

thanks for help
Regards

If it only does it when cold or after setting for a period of time it may be siphoning the gas back to the tank. I would suggest a small inline clear ( Viewable) fuel filter on the fuel line just before the carb. This way you can keep the engine box up and see how long it takes for the fuel to get up to the carb. I have seen the carbs leak gas while setting into the engine and the bowls be about empty and then the fuel line has to prime back up as well. You can also take a small squirt ( Being very sake of course ) of gas into the carb upon ignition to see if it trys to crank faster. If so its not getting fuel to the engine fast enough upon dry starts.

Randy,
If the clear filter is the common one found at many marine supplies that comes with different size hose barbs, you are recommending a potential BOMB!!! Read the specs and I feel you will find it's for outboards for suction service only and not designed for pressure service between a fuel pump and carb. I HIGHLY recommend you do some searching on the USCG regs. They are VERY specific. There are several older threads on these clear filters. Hopefully you don't have one and hopefully you haven't used hose and the plastic hose barbs.

Dear all,

I finally sligmy open the choke at cold positionand my boat now start right away.
Thanks to all

Slightly opening the choke works perfectly well. Thanks

Steve,
First, start cold without turning on the ignition. Loosen the round choke bimetalic spring housing. Adjust the housing so the choke butterfly is slightly open. Some find it handy to use a 1/8" drill bit as a guide between the butterfly and the carb throat. Tighten the spring housing. Don't drop the bit down the carb!

Ok, I attempted to adjust the black plastic choke housing. Moved it left a few clicks, but the choke opening doesn't appear more open. I am probably not understanding something correctly?

Hi Steve

Pete explained up a few posts how to adjust it, he just didn't say which way to turn the cap.

You only have 2 choices and you picked the wrong direction to turn the cap if you're trying to open the butterfly some.

It seems logical to turn it left or CCW to open it, but you need to turn it to the right or CW to open the butterfly .

It's a funky set of linkages in the housing.

Steve,
Fords are known to be cold blooded! My 302 takes about 3 pumps of the helm accelerator and then generous throttle while it warms up and that takes several minutes. What happened to the old carb?
