I have most of my bugs worked out and my engine runs good. But it does have one little idiosyncrasy that is kind of bugging me.  When starting you need to give it gas. When it is cold it starts right up if you tap the gas a few times then it idles nice and smooth until the electric choke comes off and continues to idle nice and smooth. So I am pretty happy with that.

But when the engine is warm you need to give it a little gas to get it to start. Before I rebuilt the engine it would start right up with the turn of the key. Is this something easy to fix or do I just need to deal with it?

My boat does the same thing. I have taken it in twice and it still has the same problem.  :angry

I never know when I can just turn the key & go. Plus I just learned I dont have a return spring on my throtle. I physically have to kick (not hard) the bottom of the pedal to reduce speed. I just thought my pedal was sticky or something? :(

Your old carb may have been seeping a little fuel when sitting. Causing a rich condition which would allow it to have enough fuel to fire. When its dead cold do you have to apply some gas pedal to get it to start? You might be able to adjust the choke a little.  Your new carb is probably pretty tight, I dont know if adjusting the throttle plates would help or not. ....my.02....

Your right though, its nice just to bump the key and have it fire right up. When mine runs thats usually how it works but the carb is pretty old. And I think it leaks by a little under pressure when sitting.

KC,

You are right it is a new carb and the old one did leak.  It’s funny I never thought my old leaky carb would work better than my new one. I don’t really care when its cold I just tap the gas a few times and it starts right up. It is really a pain when it is warm. Like when you are pulling skiers and you shut the engine off to talk to them or pick someone up. Then you have to fight it to get it started.

It’s really a pain when I am in the water behind the boat and my wife fires it up nails the gas and the jet wash hits me in the nuts! :eek

I have to admit that I don’t know what the throttle plates are.  How do you go about adjusting them? :stupid

The throttle plates are the round things that open when you give it gas. I think there is a really small screw that adjusts how far they are open when they are closed(boy that makes sence) I may be thinking of another type carb   :rolleyes I'll ck into it a little more :stupid Yours should be set pretty good from the factory.

Have you cked the choke when its warmed up to make sure its all the way open. I normally don't run a choke on my boats they all idle to damn high anyway, need to learn to run less cam.

As far as your boat giving you a free nut wash keep that to yer self :laugh  :rainbow  :D

Well I'm going to piss in everyone's con flakes here!  :laugh You most likely have raw gas laying on the floor in the manifold and what you're doing is (although you are squirting gas in there) opening the throttle plates to let air in. Solid gas will not ignite. Before you installed the new carb, did you take it apart and tighten everything up??, that used to be right in the instructions when you bought a new carb from Holley!. Another tip, even if you have the new non-stick gaskets, spray them with Silicone Spray, makes it even easier to take it apart!..I'll lay odds you have a leak!.. :)  :)  :beer

KC, if you have trouble getting an idle because of a wild cam, that's an easy fix, let me know!.. :good

So it could be a flooded type condition is what your saying GFR and the raw fuel is evaporating as it cools down. So thats why it starts OK when cold.   :good I'm ok wit dat.

My boat idles great cold or warm right around 900-1000rpm only problem I'm having is keeping the focking thing in 1 piece :guns  :fight  :puke

Yes it could very well be, seen that many a times and I've had the same problem myself!.. :D

Now as far staying in one piece goes, that's another story!..   :laugh  :good  :beer

When I first got it I just bolted it on and ran it. The choke is coming off completely and when it is on it is just barely on. If I give it to much choke it makes my transom black and I hate scrubbing that crap off.

When I first installed it I looked down into the intake manifold after running and did not see any noticeable fuel settled in there. That was one of the problems with my old one it was dumping fuel after I shut it down. But that doesn’t mean that it isn’t happening.

What would I tighten? Do I just go through making sure that all the screws holding the thing together are tight? I know very little about carburetors (Like that isn’t obvious).

Thanks for the help guys without you I would be lost!  :good

Is it just me or...why even use a choke,mine, I just pump twice when it's cold (holley 750 mechanical secondaries) or hit the key and it fires up everytime when it's warm...(it has the mechanical choke but I've never used it)...works great for me... :good

Yeah, just take it apart and check everything, make sure the power valves are tight(not over tight) and check the main body for flaws, they are known not to have a good flat surface and sometimes you have to tighten the bowl screws pretty tight to seal up good. And make sure the choke is wide open, you don't really need one to bgin with!..Good luck!..  :good

I just checked out my carb. The choke comes completely off in 1 minute 15 seconds from the time I turn on the key.

All the screws on the bottom are tight. But the screws holding on the bowls were loose and the screws that hold together the accelerator pump (I think that what its called it’s the diaphragm looking pump to the left of the choke in the picture) were loose. Otherwise everything else that looked like it was not an adjustment screw was tight.

Should I go without a choke? I noticed it helped it Idle when cold; are there any disadvantages to it?

Could those loose screws cause my symptoms or do you think it is something else? :stupid

Yes loose bowl screws can cause you're problem!. Choke, can't see any use for it!. In fact one of the first things I do is mill the choke horn off for more air flow!.. :good  :good  :beer

Damn Miller...that's a very clean looking engine...but what's up with the vacuum secondaries and the electric choke...looks like something you'd find on a car,not a boat...IMO... :rotflmao  :good

Hey cut me some slack guys it’s a cruiser not a gofast boat.  ;) Great now I need to put it in the mill and mill off the choke and figure how to make it into mechanical secondaries. Next thing you guys are going to be giving me a hard time for the logs and the points style ignition.   :D

I went to the lake yesterday to try the boat out with the bowl screws tightened and it didn’t seem to change things. I still need to give it some gas to get it to fire.

When I turn it over and then give it some gas it seems to labor for a second or two like it wants to start and then it finally fires up. But only if I give it gas. Is this normal am I being to picky? What else could it be? I am at a loss on this one.  :stupid  

It idles fine when it is running and has not other bad traits just the hard starting.

When you say cranks hard do you mean it cranks for a while or acts like the timing is to far advanced?

I have never ever had a choke on my boat ..  and I never will ---   :good    I personaly do not like vacume secondarys either - just my preference .     play with the air bleed screws on the side of the metering block .  mark it for reference and move it around see if that helps

scuba ya need to fix that bro -  take some pics of the back side of your peddle and also of your carb - is there at least a  return spring on it ?? it could be a ten cent fix that saves your asss ....
