Carb Question?

Michael,
You did miss something! You haven't been paying attention! Lee's been making some statements about other boats owners always seeing his transom because his boat is so fast. Then when the small minor detail of his choke not working came up, the comment was made "tongue in cheek" about that being the reason for the speedy boat!!!

Pissing match? I don't see it that way. It was just some poking on the speed subject and explained as such. You know how the speed subject gets here!! I feel Lee understands that now as well.

if your refering to the fuel and water seperator then yes that needs done as well.

Hey thanks guys! No pissing match, this all for ***************s and giggles. My little problem I think of the hard starting when hot is from not being tuned. I think one or maybe more our not firing properly. Wires may corrode through sitting over time. Which cause miss fire and and takes a full charged battery to the limit. But my boat runs real good out of the hole, and top end, just couple niches in the starting. I get it worked out.

It is a "open" ticket anytime on that coors light..

We talking speed for fun, can I cheat then? Can I borrow my friends Baja 332 with twin 502's, supercharged. He run up there about 80+..   

Thanks for the heads up!

IMO, I would start with the basics...timing points, plugs wires etc. Cheap fuel will also cause hard starts. If you are running low octane you may need to turn down the timing a bit to compensate. Be methodical about the process to avoid shooting in the dark.most folks just start turning screws without checking the basics.

Yes sir, I ran for the first 3.5 yrs with 87 and got a carb prob from it. I been told run the middle grade works wonders, and keeps the carb running alot cleaner, doesnt gum up as much..

I think hard starts comme from those probs. I had my boat tuned in 07, and have learned now that it is a 2 year job. I think those points, condesor and wires, plus your timing get way off..

What screw is that is bronze and very little for a flathead screwdriver right underneath the carb?

the secondaries throttle stop adjustment screw?

What is it's primary function?

Only 1 plug change and rotor change, and 1 carb rebuild for the sake of speed, didn't happen though. Oh, and I replaced the impeller after the first 400 hrs because someone gave me one (that was already 10 years old). A little SeaFoam over the 4 month winter layup is the only "additive" she gets. Pete, I just used some Snake oil last weekend! [QUOTE=skicat2001]    I been told by some old guys and young guys to stay away.

So what is prompting you to now want to use this snake oil? With the right concentration of SeaFoam and aviation fuel, you will break 50 mph!



Hollywood I like you and but that wuz wrong..
Seafoam i am going to give it try. You old timers know your stuff so I better listen..

Hey thanks.. So where is the idle adjustment. Is it hard to do.. I would like to adjust mine about 200rpm

Listen, no offense, but if you are having trouble figuring out the idle screw, I would suggest doing some reading on Holley carbs and familiarize yourself before you start adjusting. Go to Youtube and type in Holley carb adjustment. You should come up with some videos from Holley that walk you through adjusting a carb properly. Here is a link for idle speed:

Thanks Ernest.. Watched that video great stuff.

pour half the can through the carb with the engie running increase the rpm to about 2000-2500k as your pouring it in and keep up the rpms until all the smoke clears from the exhaust, then pour the rest of the can in the tank now you cleand the top-end of the engine and the rest in the tank will take care of the carb internally.

Seafoam is sold in 16 oz can at O-reilly's
