Description

Tillotson 225RS FM22 26mm Round Slide Carburetor


The Tillotson FM22 is a high-performance, race-calibrated 26mm round slide carburetor explicitly designed for the Tillotson 225RS T4 Racing Engine and built upon the widely recognized "VM22-style" platform, which itself is based on the PZ26 design. The FM22 brings precision, reliability, and race-tuned performance straight out of the box.


Unlike generic knock-off versions, this carburetor is calibrated by Tillotson for optimal fuel delivery and throttle response, tailored to the 225RS engine. This makes it a go-to choice for racers and builders seeking consistency and performance in competitive environments.

FAQ

Frequently Asked Questions (FAQ)


Q1: What engines is the FM22 carburetor designed for?

A: The FM22 is specifically calibrated for the Tillotson 225RS T4 Racing Engine. While it's based on the popular VM22/PZ26 design, it is tuned by Tillotson for optimized racing performance with the 225RS platform.


Q2: Is the FM22 compatible with other clone engines or Predator 212s?

A: While it may physically fit other clone or small block engines, it is calibrated for the 225RS. If used with other platforms, you may need to re-jet or tune the carb for proper performance.


Q3: How is the FM22 different from a generic VM22 or PZ26 carb?

Q4: Do I need to rejet the FM22?

Q5: Can this carburetor be used for street or non-racing use?

A: This carburetor is designed for racing applications only, particularly in the T4 racing class. It may work in other builds, but it’s not optimized for general-purpose or street use.
