Overall Assessment

The product, a carburetor replacement part, has been praised by customers for its high-quality machining and perfect fit. Users often purchase it for carburetor rebuilds and find it useful for adding multi-carb linkages. This part is recognized as crucial for improving vacuum readings, reducing leaks, and ensuring smooth operation. Some customers noted it's a bit oversized, requiring minor adjustment for fit, but overall, they appreciated this characteristic as it compensates for worn carb bases. They also highlighted its practicality, as it can rejuvenate older carb models or be used in custom lengths. Despite a few minor installation challenges, customers found the product superior to competitors' offerings and would likely purchase it again.

Just What the Doctor Ordered...

I ordered this shaft and a 9/32 reamer and found the combination to work well. Even after reaming my carburetor throttle shaft bore to 9/32, a bit of honing or lapping was required (with some valve grinding compound) to make the shaft turn easily with the throttle plates in place. My application was a single carb setup, so the extra length of the shaft was cut off.

Larger than expected

Even using the suggested drill bit size and reamer it was too big to fit in the carb base. I milled it down to get it to spin freely

This shaft is just what you need, to get the old rusty 94 working as good as new! The hard part is getting the old shaft out.

This product is awesome. The throttle shafts are smooth and the slots for the plates are crisplu cut without any burrs as is the threading for the screws. It is a bit oversized to make up for time worn 94 bases so expect to ream the holes a little. Overall a very impressive replacement part
