Reproduction Throttle Rebuilds

 

Click on photo to enlarge, they will open in a new window.

 

 

If your newly acquired reproduction throttles are not functioning properly we are offering a rebuild service that will address some of the issues we have seen.

 

Typically the air flow can not be balanced sufficiently by adjusting the air screws.  There may be 1 or more barrels that require the air screws be fully closed,  but will still flow too much air.  Other problems include sticking throttle plates and/or loose bushings. Our basic service will usually be sufficient to make the throttles function properly. 

 

Basic Service:

Completely disassemble. Replace bushings. Fit shafts to new bushings.  Fit existing throttle plates, if possible, to housings.  Assemble and flow test.  $1600

 

Additional Service:

Machine and fit new throttle plates, if needed, to existing bore.  $300

Overbore barrels to correct out-of-round defect. $400

Replace steel links with OEM style aluminum/chromate.  $140

Strip and replate existing hardware to reduce brightness, except studs.  $220

Top studs, replate.  $80

Rebush bellcrank for tighter fit. $40

 

Big bore options top and bottom. Call for price.
