Still fighting the weak vmax

[pennsburgian]

Lost my old post ??..Posted last week about my 98. turns out I have no fuel to #1 carb...tried a seafoam soak..tried compressed air...had some air flow...not sure how much is enough..had the bowl cover off and the needle out (and float) blew through with the needle out...not a ton of flow but some...new fuel filter...no flow out drain tube when I open the drain screw...running on basicly 3 cyls...What is the brass plug directly above the needle and seat...anybody remove one? tricks for unclogging ?

The brass plugs cover the air/fuel mixture screws. They get clogged easily, and are a common source of carb problems.
Do the shotgun cleaning method.http://vmax.lvlhead.com/tips/shotgun.htm.
The video explains how to remove the plugs.
Cheers!

Are you sure the drain line to #1 isn't plugged....fairly common.

The brass plug can be drilled & EZY outted.

I think he might be referring to the float needle seat. If so, no clue how it would come out, if it comes out.

 

[beezer66]

The needle seat comes out like removing a stuck case when reloading ammunition. Drill and tap the plug. Place a spacer and washer over the plug; thread in bolt and tighten. As the bolt is tightened, it comes up through the spacer. Buy a RCBS stuck case remover kit for reloading, it has everything you need.

He is referring to the seat - not the a/f plug----it can be jacked out a few ways buy not advisable unless your float needle is stuck in there---rare.

Oh, the plug over the seat? Some are brass, some are aluminum.

Jack it out with a 'C' clamp, the screen will flatten on the underside of the plug but can be 'domed' back out with a pencil eraser or similar.

Not much point in removing unless there is obvious damage.....toothpaste on a Q-tip, chucked in a hand drill, will polish the seat with it left in the carb body.

Yea I'm thinkin' Not. Hopefully he will reveal.

Yes definately referring to the plug over the needle and seat...not pulling it un less absolutely necessary...just wanted to make sure there wasn't a brass screen under there restricting my flow.still kinda baffled by this one. been around enough carbs in my day that this just doesn't make sense...never saw a blockage that 100 psi of compressed air wouldn't blow out. It may be getting better the more I ride it but I don't want to hurt it running around lean, I will see what this week brings , may have to pull the carbs and ship them out to danny..lol @ pepsodent !

Yea, I googled it before I posted, but it didn't fit my jingle. If it does not fit, you must acquit. On a side note, the 5th dentist for trident had a squirrel running up his leg.
