Ok here is my question. I have duel weber 48 on a 2332. I have been thinking about going to a single carb for Simplicity. Dose anyone have any recommendations. |

NO, don't do that! I know a single carb may be preferred on Off-Road machines due to dirt and perhaps just ad intake's to the dual to get them breathing somewhere in a better location. But really IT makes a nicer simpler better running setup with duals. Opens up things you can get to things easily no Pre-Heat needed either. _________________ 1960 Beetle And 1679cc DP W-100 & Dual Zeniths! |

What isn't simple about the dual carbs? _________________ Amonster Motorsports

The buggy is off road and it manly in the mud and sand. Duel cards are easy, just thinking andoyt simplicity on the trail. |

What someone once told me, dual 2 barrel carbs on a VW motor is like tuning 4 Briggs & Stratton motors on single crankshaft.... You just tune one cylinder at a time (once you get idle speed screws set)...
Really... A lot of people go through a lot of processes of using snail or manometer or what ever to tune, but if you really understand how to tune the carbs you can do it with nothing more than a screw driver and your brain (ears)... Maybe not the best tune but it will "RUN"...
Your issue may be the 48's, IDF or IDA just may be to big... I had a borrowed set of 48 IDF's on a 2180 and it ran good, but owner wanted them back so I moved a set of 44 IDF's off another engine to the 2180 and retuned them (the 48's) and car actually ran better....
What 48's do you have (IDF or IDA) and what is your reason for wanting to remove them.... It all may be tuning issues you are not aware of as to why you are displeased with them...

Your going to have a hard time getting one carb to run that big of a motor, I could see one running it as long as your cam isn't to wild. We got my friends 2110 to run on one 44IDF but he has a angle 100 cam, and stock valves in the head. It's super torque y on the bottom end but it won't rev past 4000 rpm. |

Or, I have a set of 44 IDF's that I could swap you for your 48's |

Single carb for the win. With a turbo below it.
Turbocharging an open engine VW is so redonkolusly easy it blows my mind more aren’t boosted |

But it scares the hell out of people who can not even tune a B&S lawnmower motor (X4)...

That’s just it. It’s a heck of a lot easier to tune than dual carbs ESPECIALLY dual single Venturi
Carb, turbo & wideband
No manometer, no snail, no constant linkage hanky panky and no Jets so small a grain of salt can plug them
Just glorious torque like an NA bug motor will never have that will behave like a stock motor driving normally |

New Mexico has 600 grit air. what are called boulders elsewhere are called gravel here. Investing in a turbo would be like investing in a Trabant dealership in Beverly Hills _________________ 73 Beetle Baja, Ghia front brakes, Type 3 rear brakes, 2220 ( 94 X 80 ), Weber Progressive, Bosch SVDA, '97 Mustang seats

Not to mention the increase in grief to the gearbox. Not such an issue in sand dunes, though it just might be an issue in mud depending on the nature of the mud you play in. _________________ Richard

I tried a single Dell DRLA many years back. Kept having icing problems during cool mornings. Switched to duel Dells (with jet drs) and never had an issue again. Tuning is simple. There was/is a Dellorto bible out there, so guessing there's something similar for the Webers. If so, a wise investment. _________________ Yes Virginia, beer can make you smarter.

ditto - ZENITH 32NDIX just make sure it gets enough air. When I went with a UMP air box with a velocity stack and the big filter, it went from running great to Frickin amazing! _________________ rant _ classified ads with out pics are almost worthless |

Its sacrilege to most on this site to move from a dual setup to a single. But, I think it can be done quite successfully. Had a friend who loathed the hex bar linkage and the issues required to work out and disliked the susceptibility of the weber carbs to get fouled by the tiniest particle, especially being used off road. He transitioned to a single 4 barrel holley carb and has enjoyed easier linkage tuning and less maintenance due to fouled jets. Not saying its for everyone, but it can be made to work as well, if not better, under certain circumstances. |
