Description

The PWK24 is a 24mm bore slide carburetor setup and tuned for the popular Honda-Clone engines, including Tillotson, Predator Wildcat, Ducar, and the original Honda. 


The d-shape slide provides better flow characteristics than round slide carburetors to provide better response and tuning consistency. Don't underestimate the carburetor's 24mm bore size. The carburetor flows roughly 90cfm at 28 inches, providing more than adequate airflow for stock and most big valve ported heads. The carburetor works with most modified cruisers and race engines running on gas. However, we often get questions about whether a carburetor will work for a combination, so here are our recommended engine specs to get the most from this carburetor.

Now includes velocity stack/air filter adaptor for common 2.5-inch air filters. 

Recommended Engine Specs:
223-236cc
Camshaft 275+ lift, 240+ duration
28-36° Ignition Timing
Ported Head with 27mm+ Intake Valve

Note: All Carburetors are affected by atmospheric conditions(Barometric Pressure, Humidity, Ambient Temperature, Elevation, etc.). Each carburetor is calibrated, tuned, or jetted for the application but may require additional tuning depending on the conditions. 




FAQ

Is this carburetor tuned for race gas?
Race Fuel is specially formulated with different characteristics based on racing conditions. The carburetor itself should have no problem running a race fuel regardless of the octane, but octane rating is not an indication of added performance, just the ability to reduce detention. However, oxygenated fuels or containing accelerants may need additional tuning due to changes in the air-fuel ratio. It's best to contact your race fuel provider to ensure the chemistry works for your application and if there is any need for tuning adjustments.

Can this carburetor run or be tuned for E85 or other ethanol blends?
We don't recommend ethanol for any carburetor used for small engine engines. Ethanol percentages are seasonal and regional, and you may experience significant changes in performance and struggle to stay consistent with carburetor tuning. Ethanol also draws a lot of moisture. You may have a higher water content from pump stations, or if the fuel is bought from a race shop or fuel blender that isn't properly stored, it will be contaminated with water over time, which hurts performance. Since lead has been removed from many of our polymers used for o-rings, inlet needles, etc, ethanol can cause them to shrink, grow or disintegrate over time. If possible, use pure gasoline. 


Does the intake match the d-shape port of my engine? 
The intakes are designed specifically for the Tillotson JT-207 d-shaped port. There may be slight variations depending on the brand of head and engine. Only the Ducar 212, Tillotson 212E, and Ghost 212, which use the Ducar Hemi Head, have a mismatched port that may require some port matching. 


What is the barb fitting for on the intake?
The fitting is to get a vacuum signal for external fuel pumps. The intake is the recommended place to get your pulse rather than the crankcase or valve cover. 


Is the carburetor for gravity fed or by a fuel pump?
Both. If you are using a stock fuel tank, the fuel tank outlet needs to be above the fuel inlet of the carburetor. In most cases, it is not, so the tank needs to be raised. When relocating the tank or using a remote tank for gravity feed, keep the tank within a couple of feet. If the tank is too high, it may pressurize the fuel enough to force the inlet valve open, causing a rich condition. When using a fuel pump, use a round-style vacuum pump. Do not use electric fuel pumps, or if using some dual feed pump will have too much fuel pressure and will force the inlet valve open, causing a rich condition. The best pump to use is the Walbro FPC-1.


How does this carburetor compare to the VM22 Chikuni(Chinese Mikuni) Carburetors?
The PWK is superior in every way. The tuning, idle, throttle response and power will be better than most round-style carburetors. 


How does this carburetor compare to the VM22 Chikuni(Chinese Mikuni) Carburetors?
There are marginal differences in performance when both carburetors are tuned. However, the PWK is a better value due to the lower price of the carburetor.


How does this carburetor compare to Tillotson or Diaphragm Carburetors?
Properly tuned Tillotsons designed for your application have performance and tuning advantages. However, Tillotsons or diaphragm carburetors on 4-cycle engines are not made to idle and will be finicky if not used properly. Unless you are kart racing, we normally recommend using a bowl carburetor.
