~ Pre '68  Housings: Re-machine one pair of housings from '65 to '68 with non-adjustable accelerator pump rod, and a spring type shaft coupler. This service includes installation of an updated coupler and adjustable pump (update kit).   $1840.00

 

~ Post '68  Housings: Re-machine one pair (left and right) with adjustable pump and later style shaft couplers (barrel type)   $1740.00

 

 ~ Pre '68 Complete: Re-machine a matched pair of IDA/IDS including total rebuild, plating hardware, bench testing, re-assembly, update kit installed.   $3150.00

 

~ Post '68  Complete: Re-machine a matched pair of IDA/IDTP from '69 on; includes total rebuild , plating hardware, bench testing, re-assembly, ready to run   $2950.00

Worn bushings are replaced with machined brass bushings at each end of the housing. Most also require an internal bushing for the long shaft.

 

New OEM M8 ball pins.

 

A very clean pair of IDS housings.

 

If the original throttle plates are not bent, we can increase their overall diameter and then machine the plate to the bore size with the correct beveled angle. If the plates are bent, or at the customer's request, we will machine new throttle plates from metric spec sheet brass.

 

 

Updated shaft coupler replaces the unreliable spring type coupler.

 

 

Updated pump mechanism allows for accurate metering of pump volume. The volume of fuel from the early non-adjacent pump is somewhat arbitrary.

 


 

Description of work:   All work includes lapped barrels, new machined brass bushings, throttle plate machining and fitting. Ball pins on throttle arms will be replaced with non-threaded OEM type. Throttle shafts will be replaced as necessary and for an additional charge.

Instructions:   For No. W-1 and W-2, send empty housings with throttle shafts, butterflies, and throttle arm still in place; do not take apart!

For No. W-1c and W-2c, send complete carburetors; drain the gas out, remove air canisters and intake funnels which are not needed in the rebuilding process

Shaft Wear:   In many cases, the throttle shafts are reusable even though there appears to be too much radial play in the shafts. This might be simply a bushing problem, and not a problem with the throttle shafts. Even gross radial movement can be misleading.  There is no way to determine if the throttle shafts are worn out unless they are removed from the housings and measured with a micrometer or caliper.

Important!   Only OEM Weber carburetors can be successfully rebuilt under warranty. Carburetors must have 'Made in Italy' stamped into float bowl.
