When I got my '71 914 project car, it came with a 1911 motor that had apparently been run on carbs, but the carbs did not come with the motor. I have no idea what cam was installed in the motor when it was rebuilt into a 1911, nor do I know what carbs were on the motor before I got it. What would make the most sense for getting this motor running again? What carbs would make sense to put on this motor? Any help would be appreciated.

40mm dual webers, pro rebuilt Italian is the best, reason I say pro is care has to be taken that the shaft bushings are not worn.
The EMPI HPMX made in China, Weber IDF copy are ok new, but used the early ones had big issues. Scrap the linkage and get a CSP center pull or the the cable job from Tangerine. |

Personally I would go with the EMPI HPMX 40s.
Have had them on my 1.7 for a few years now with no issues. Only ~$500 for a brand new pair. |

Dell'Orto 36es were the preferred carb for a while. I believe they haven't been made in quite a while so may be hard to find. Weber 40s have been something of a default choice for decades. More recently, I have heard more about the types mentioned above.
Consensus seems to be that the Kadron copies of old Solex carbs aren't very good, unless you get really lucky or are willing to put a ton of work into them. Other options would include a Microsquirt-controlled independent throttle body injection setup. (IMG:style_emoticons/default/biggrin.gif) --DD |

If I was looking these days, i’d Look for an EFI setup (Microsquirt?) as today’s fuels don’t play nicely with carbs.

More recently, I have heard more about the types mentioned above. CB performance imported Dellorto's a ways back pretty much ready to run,some come up on theSamba.com from time to time ,others are around still these are mostly "take offs" from Alfa's and require a bit of work to get right,I currently have 2 sets,the biggest issue is when you want run a vacuum dizzy , the Alfa sets only have a vacuum point on one of the carbs in the set and you need to drill one carb and fit a second pickup or fit an anti-pulse on one carb as Alfa did. Many in the "know" rate the Dellorto's above the Weber due to being a much newer design,I believe Jake is a fan of them, contrary to what many say there is plenty of spares around for them. |

I have heard that they have more progression ports and transition from idle jets to mains much more gracefully. No experience myself.

I think someone has a video of the HPMX out performing the Webers ,think it was on the CB Performance website...worth a look (IMG:style_emoticons/default/biggrin.gif) . |
