 |
|
| I inherited this bug, and it has a 2L high performance street ( mild cam and head work) motor in it. It has dual 44s and was wondering if I could put a progressive set up on it to simplify things for me. I would consider dual kadrons but want to keep it as simple as possible. Any thoughts? |

If you switch to a progressive you will lose hp and lose MPG. Additionally you will have to set up the proper preheat to get them to work right. Like we explained in your other post, once you do some investigation/maintaining, and repairing on your current dual 44 idf set up, you will be a very happy camper. Dont move backwards. Move forwards.

I think you would be mildly crazy changing them out to 'simplify' things for you. Learn about the carbs, (it's not that hard) and you will be happy you kept them. A progressive carb on that motor would be ridiculous.

Not to mention the progressive is more of a pain to tune right the first time than duals.
You couldn't ask for a better set of carbs to start with and learn on..
Buy the Weber book and ask questions.
MHarney would be a good person to get in touch with if you need parts or tuning help but you should do some homework yourself first.
If we haven't talked you into them then PM me when you are ready to sell them.

| I have a Weber progressive on a 1914 set up dialed in and tuned perfect, I would trade in a heartbeat for your 44's. If that tells you anything. |

NO    
Dude, seriously, take a deep breath, exhale and please read these tech articles before you do anything else. Once you understand what's in these articles you'll see that keeping your IDF's is a smart thing.

I had dual kads o my 1776 i then built a 1914 and went to 44s.The idfs are easier to deal with alot smoother then the kads.These were my first experiences with duals.IMO it was not bad to get them working
You stat with carbs that need work or bad linkage you will never get it right.

| I spent a few years with a Progressive carb. first cause some people advicedme wrong! and i was a litle affraid of two carbs... but a few months ago i installed my set of 44 webers and couldnt be more pleased,more performance better mileage, i dont live in the usa and dont have people near by with duals, i had to install and tune by myself and ask a lot of questions here, read books and like that! |

The kadrons are very simple far as being really crude only a handful of jets, and the airfilters are easier to fit
BUT if you get a good linkage, and an airfilter setup that stops dirt, and make sure the carbs are built right, it will BECOME 100% "reliable" with your 44 webers |

no not because ther cheep, because the owners or guy adding the "HIGH PERFORMANCE" carb is skeered of 2 carbs.I have seen it somany timesI could puke,and the guys that can do it all better than anybody else puts on the duels,dont know how to 1 tune then, 2 sync them,3 install them corectly,4 add fuel filters,5 use air filters,6 runs a oil hose to the airfilters on his 86%blowby motor. and thus the reason for the, "new"lightly used for 2 months carbson the market witch leads them to the progressive&singles, witch they never get working right either. |

x2
i was one of them... mostly cause nobody over here have duals. the guy i bought mine had them from like 8 years ago , this guy bought a lot of things for his beetle, including carbs but due to the poors mechanics over here they couldnt even make it IDLE, this guy sold his beetle and just keep the carbs in a box(nobody wanted to buy it since they had problems according the local mechanics) till i ask him about the carbs, he sold it to me and he still cant believe that my carbs are running like that. he swore to me that the problems with the carbs was the IDLEING system , that this carbs NEVER idles... the mechanic set idle at 1300rpm.... Guess what?? i bought it, took it apart(luckily he took out all the gas before storage) cleaned it and SET the floats that were wayyy off(never done), changed the gaskets, installed it , did the pre tune procedure and woila. know some peolple ask me who did it , who tuned it, and when i say ME they just think that is not as impossible as the mechanics were parroting... know they idles at 900rpms steady... good gas mileage, better than the proggresive , more performance. |

Stick w/ the 44 IDFs. 20 years ago, I had a pair of 44 IDFs on a mild 1967 (92 x 74) engine (Engle W110 cam w/ ported and polished stock heads) in my 1965 ghia coupe. That thing pulled HARD w/ the IDFs and still got around 30-35 mpg on the highway despite the low 4.375 ring and pinion. My record was 36 mpg on one trip! Yeah, it only got around 20 mpg if I was flogging it around town, but the highway mileage was incredible. Plus, it had excellent drivability.
