Does anyone besides me remember seeing someone brace their IDA's to the fanshroud? I remember a few years back someone here was bracing their IDA's to the fanshroud to help keep manifolds from loosening up.  They reported that it worked great. 
Whoever may have tried it, how did it hold up against the expansion of the motor after warmup?
Cheers,
Matt

sorry, slightly off topic but has anybody gone the route of soft mounting their 48IDA's?
I know the DCOE side draft carburetors are required to be soft mounted with rubber isolators and special spring washers/nuts. Something I've thought about recently is if the IDA would benefit from similaer mounting? Which leads me to another question to myself, the issue of heat soaking the carbs full of fuel (after a good drive, then parking car for 20 minutes or so, then re-start car, engine runs poorly for a bit....), this has been an intermittent issue my car has has for a good few years now, still scratching my head as to why, I am beginning to wonder if the solid Berg intermediate mount is a contributor. A good friend of mine does a lot of hot rod 911 stuff and he says some of the guys insist on solid engine mounts and he's been seeing fuel issues as a result. Apparently the fuel "froths" up. Just wondering if there is a relationship on a solid mounted VW engine with Webers. Any thoughts?

Jim, i am using ceramic spacers between the manifold and carb to stop this.

Jim, my mate who is racing a alfa Giulia (with 40 DCOE s) also use those allu/rubber isolators... they are known in the racing world here in Europe

But there is a type4 company in germany who is selling them for 40mm IDF s
http://www.wilke-motorenbau.de/produkte.htm
look for ''Satz Schwingungsdämpfer'' 125,00 EUR

But can t find them for Ida s

Kind Regards Edgar

Had some thick phenolic blocks when I had the Datsun and some thinner ones for the 40P11's on the '63 bug.  IDA's on tall manifolds are already too close to the deck lid so probably more trouble then it's worth.  I feel that manifold breakage (at least for me) may have something to do with how well the throttle shafts work in the carbs... any binding from worn accelerator pump rollers and cratered pump ramps makes mashing the throttle harder.  Something's got to give.

Domminick,

Do you have the spacers in stock for the IDA's?  Are they urethane?

I thought these were more to help prevent heat transfer  Undecided

Thats why I used them on the "shortened" race trim manifolds I built - seemed to work pretty well  Smiley

More off-this-topic, these are the phenolic spacers for IDA's by CSP. Just let me know.

Hi Rick
Yes, they are in stock and made from a special formula urethane for the IDA & IDF carbs in red or black.

And i think these will solve jims problems, rather than vibration from solid mounts.

Hmmmm Ceramic isn't exactly "soft" and though they did help prevent the heat transfer I did find that the nuts from the carb to manifold (x3) did work loose after a long hard trash  Undecided

But as someone else has mentioned this maybe to do with incorrectly set up linkage - After all I did build the linkage myself  Cheesy
