Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • 2013 Troy-Bilt TB146EC tiller model 21AK146G766
  • 2012 Troy-Bilt TB146EC model 21AK146G766 only when 753-06258A is confirmed

Product Overview

If the TB146EC was parked with untreated gas, it may be difficult to start the next season, hunt at idle, or quit when the tines load the engine. After checking spark, compression, fresh fuel, the primer, and intake seals, a restricted carburetor may be the missing repair.

This is for the 29cc four-cycle configuration, so fuel is not mixed with two-cycle oil. Use the full equipment model and carburetor layout to confirm the part, not the TB146 name by itself.

  • Fits the identified 2013 TB146EC tiller application
  • Replaces updated reference 753-06258A
  • Supports normal fuel metering after a confirmed carburetor fault
  • Useful for varnish, corrosion, or damaged primer circuits
  • Aftermarket small-engine replacement part

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.

Model names and year ranges are a starting point. Match the original reference number, configuration, connections, mounting points, and product-specific details before ordering.

Frequently Asked Questions

Q: Do I mix oil with the gas? A: No. The TB146EC application is four-cycle and uses engine oil separately.

Q: Why does the engine run only with the choke on? A: That often indicates a lean condition from restricted fuel passages or an intake leak, but diagnosis is still required.

Q: How do I confirm the year? A: Use the full model number 21AK146G766 and match 753-06258A plus the physical carburetor.
