Looking for a weber rebuilding/cleaning service Options

[casey944]

Afternoon!

My 914 has a 1.7L engine(original) and I am running a pair of 36IDF carbs. I have rebuilt them personally, had another relatively local 914 specialist rebuild them and I am still not entirely happy with the way they perform....

Transition and coming on to throttle up to when the main jets come on seems to be the issue.

Is there a rebuilder/cleaner that everyone on here recommends? I figure some sort of ultra sonic blasting to clean out the ports/chambers that I am not able to get to would be the best.

Any insight?

Possibly also rejetting suggestions might be good as well.

Thanks,
Casey

Unfortunately, everything else must be spot-on before you tune the carbs. Make sure your getting spark to the chambers, fuel is at the appropriate pressure and clean, valves are properly adjusted, if you don't do this, your tuning to overcome the problem and not to optimum performance. Once you have done all of the background tuning, you really need to know what the engine is doing under load as far as the Air:Fuel ratio is concerned. Without that knowledge, no one can really tell you that your jetting is spot on. I'm not sure what they based that on but in general, people run fat A:F ratio to overcome other problems. Type IV motors tend to like a fat idle but tighter control above that. Remember, you are cruising on city streets on your idle circuits most of the time. I run both of my cars at around 13.5:1 target. One is a fuel injected 200+HP Type IV, the other a triple Weber 240Z. You can get that kind of control but you have to have all your other ducks lined up and quacking in unison before you do...
