I've recently installed a weber 48 ida on my 12A and I've searced and searched for what people have used for a linkage to the OMP. I've found a bunch of linkages on pierce manifolds and was wondering if anybody knows which one will work.

My car goes back on the road next week and this is what's still holding my back.

Also, does anybody know the size of drill bit needed to make the third progression hole?

Any help/ suggestions would be much appreciated.

 

IDA comes in either right or left carb of a VW motor. Which one do you have?

for progression hole, just use the closest size to the original two. I just cant remember if I used an index or number drill.

 

Here's a pic.

 

thats bottom pull so it can be done. I get a pix on how I did my carbs tomorrow.

FYI:
To identify a top pull IDA, the fuel inlet faces the motor. Unlike bottom pull, the linkage will rotate clockwise (if your facing the carb from front of car) so the omp rod linkage will be facing the header side. Imagine how the OMP rod will look like: a retard. Pix tomorrow will explain it better.

 

whats everyone doing for the throttle cable bracket?

 

Thanks Wacky


Are you talking about the bell crank?

 

nope. i'm talking about the part that would hold the end of the sheath of the cable.

 

just started a thread on the 3rd progression hole, still waiting some specific sizes

as for the omp lines you need to tap into the fuel bowl(engine side, and extend your omp tubes to reach the new location), manipulate the old omp linkage to operate(open/close) as it did on the stock nikki carb.(i just went with premix and blocked off the opm).

and for the throttle cable sheath stopper, a bracket needs to be made that will hold it in place, i attached mine to one of the bell housing bolts.
