FAQ

Q1: What engines is this carburetor kit compatible with?

The HL-304WX-19K EC Dominator is specifically designed for Modified Briggs & Stratton Animal (Model 12) and LO206 engines running on pump or race gasoline. It is not compatible with methanol-tuned engines or stock LO206 classes that require sealed carbs.


Q2: Can I use this carburetor with ethanol or E85 fuel?

No. This carburetor is not compatible with E85, E91, or any ethanol-blended fuels. Ethanol can cause swelling, degradation of internal components, and tuning instability. Use only pure pump gas or racing gasoline.


Q3: What type of fuel pump is required?

You must use a round-style Walbro FPC-1 or TFPC-1 fuel pump. We do not support:

  • Briggs & Stratton square pumps
  • Mikuni or Mikuni clones
  • Plastic Walbro knockoffs
  • Electric fuel pumps

If you're considering an alternative, contact us before installation.


Q4: What are the starting needle settings for tuning?

Initial carb settings are:

  • High Side (H): 1 turn out
  • Low Side (L): 2.5 turns out

These are starting points — final tuning depends on track conditions, fuel, air density, and engine setup.


Q5: What’s included in the HL-304WX-19K carburetor kit?

Each kit includes:

  • EC Dominator HL-304WX-19K Carburetor
  • CNC-Machined Intake Manifold
  • Walbro Round-Style Fuel Pump
  • Inline Fuel Filter
  • Complete Linkage Kit

Everything is prepped for quick installation and race-day performance.


Q6: Is this carb legal for LO206 class racing?

No. This is a modified-performance carburetor designed for open or modified classes. The LO206 class requires sealed stock carbs and this kit is not legal for that specific class.


Q7: How is the EC Dominator different from stock Tillotson carbs?

The EC Dominator is hand-machined, blueprint-calibrated, and race-tuned. Features include:

  • Infinite-radius venturi
  • Mirror-polished throttle bore
  • Matched velocity stack
  • Custom-calibrated fuel circuits
  • Hand-fit throttle shaft and “Trix” screw
    These modifications provide improved airflow, throttle response, and fuel control — ideal for competitive racing.
