Does anyone have a float gauge for the 32/36 weber,mine need's set,and I cant find a happy medium for this carb,seem's to be alittle tempermental.Also any tip's or trick's to making these carb's work for wheelin.

webber ahhhhhhhhhhhhhhhhh

fuel pressure......i dont know what motor your running but as far as the zuk motors go all you need is about 2-3 psi go beyond that and you will have touble.....
keep the float level as low as possible and you will have less trouble with flooding on steep inclines........recomended placement of carb on the zuk motors will have the carb flooding going up hill...........

some people turn the carb 180% so it will flood going down hill......the flooding that i am talking about only happens from about 55% of incline.......

there are a couple different methods of modding the carb too change how the float bowl gets it vent.........one is just block the vent with epoxy with a tube exstending upward out of the epoxy too raise the level of the vent....i tried this method and it did kinda sorta work until the motor got up to about 3k rpm at which point the motor would bog down because the vent tubes could not flow enough air into the float bowl and the resultant vacume restricted fuel flow......

the second method i have read about reqiures completely blocking the stock vent and drilling a pasage from the evaporative fuel vent into the float area but the above would more than likely apply to that also if the passageway is not big enough to flow more air than the fuel consumption of the engine then a vacume will be the resultat higher rpms.........

my last thought would be hacking the bowl vent out of my spare webber and soldering it in place on top of the stock bowl vent {yes i can solder aluminum}
this would exstend the height of the bowl vent and maybe give me another 15-20% of incline before the gas would spill out ............sorry for the book.....

No need to be sorry for the book,that's some good info...Thank's.
I'm running this on my 22r.When I first put the weber on It ran pretty good,but felt it was starving for fuel in the 3000-3500rpm range,so I bumped the fuel level up and since then it's been very tempermental cutting out on flat ground,just dont want to run.I've tried lowering it back down,back up and so on.the only time it run's good is if I stay way out of the pedal.

When I raise the fuel I'm getting gas coming out of the adapter plate's when I shut the engine off,When I start it up it all dry's up,so I went and bought some thick make youself gasket material.Leaking through the adap. plate's isn't good and probably one problem I'm having.

Also what's the little hole for,or what's it do,that's about halfway up the backside of the bowl?

the adapter plate

the adapter plates are a really sore spot about the webber setups ......i finaly wound up useing a loc-tite product or the the like that was meant for permanent {you gotta heat it up to get rid of the stuff type applications} stay in forever type stuff.......

this works the best and held everything in place for about 6 months but it did work the best.......

roadless gear at one point in time offered a intake with the the adapter tig welded too it {for zuks} this would be the real fix for this problem......

the main reason i went too a webber was that the factory reman units that i was able to find in the phx area were just crappy......no one could tell if the mixture control valve had been replacedwhich is what goes wrong with the zuk carbs.....at the time the m/c valve was listed as a 147.00 dollar part but nobody had them or could get them.......so i went with the webber no m/c valve on that little bugger........

will the webber pass the emissions testing crap some say yes some say no.... the last time i was in salt lake i tied too get the guys at one small garage to run my zuk on there machine just too see if it would pass or fail but they would not run it ......which kinda ticked me off i just wanted too see where it was at emmision wise just too have the hard facts in hand..........

Well I've got it to run right,It's amazing what a $2.99 part will do.I changed the fuel filter and i'm getting fuel throughout the rpm range.
It seem's like I just replaced it not too long ago,must have been longer than I thought,it was full of crap.
Now The snow need's to go away,so I can climb my favorite hill and hopefully get this carb more incline ready before I go to moab.

webbers gooooood

if you can fix it with a screw driver i like it......and it is like any thing else you mod on your ride you gotta tweak it a bit to do it your way .......that is what i like about the 4wd thing .....have it your way have it your way have it your way with {insert name}................

glad too see you are likeing it...............
