A tool like this in-line ignition tester can help identify or rule out an electrical problem. It’s important to rule out other potential problems before deciding a carburetor is at fault.

Finding the source when you have engine problems

If an engine that has been sitting for several months fails to start, don’t automatically assume the carb is the problem. There are some other basic checks to make before tearing into a rebuild. Some old mechanics used to say “most carb problems are electrical.” What they meant was what people often assume is a […] Read more

Carburetors can be complicated, but careful attention to detail during disassembly and a methodical approach can make rebuilding one a straightforward job.

How to overhaul your own carburetor

In this instalment of Shop Class, we get back to the basics of carburetors

In the mid 1980s, carburetors quickly gave way to fuel injection systems in new cars and trucks. But it’s likely there are still a few carbureted engines on machines in nearly every Prairie farmyard. That handy ATV and small grain auger engine are probably two places they can be found. And, of course, there is […] Read more


How to pick a replacement carb

Occasionally when working on older machines, it’s common to come across a carburetor that is no longer serviceable. But finding an exact replacement can sometimes be very difficult, or prohibitively expensive. If a new OEM replacement isn’t an option and a search for a used part isn’t working out, there is little choice but to […] Read more

At idle, air flows around the throttle valve through the idle circuit and provides a lean mixture to the engine. The air-fuel mixture varies for maximum efficiency at different open throttle positions.

Carburetion. It’s all about the air to fuel ratio

There are three basic types of carbs: updraft, downdraft and sidedraft. Those terms refer to the direction of airflow through the carb’s air horn. A downdraft, the most common automotive type, mounts on top of the intake manifold and air flows down through the barrel and into the engine. And updraft, as you’d expect, mounts […] Read more

How manufacturers tried to convince farmers to buy trucks in the ’60s

Stacked! Built!” are the first two words in the body of this Mercury Trucks advertisement from the early 1960s. Clearly, they have that nudge-nudge-wink-wink feel to them. I’m pretty sure those terms had the same double entendre meaning back then that they do today. No current marketing manager would ever let that kind of ad […] Read more



The Canadian unveiling of the 2017 Ford Super Duty took place in November at the Canadian Western Agribition in Regina.

Trailer towing capability is a priority for the brand’s new Super Duty trucks

Most of the new vehicle introductions in this country have typically taken place at the Canadian International Auto Show in Toronto. But Ford didn’t choose to use that venue to unveil its 2017 line of Super Duty trucks. Instead, the brand picked the Canadian Western Agribition in Regina last November to show potential buyers what […] Read more


The Silverado is available with three different engine options, a 4.3 V-6 along with 5.3 and 6.2 litre V-8s.

GM gives its Silverado truck a facelift and some digital updates for 2016

The 2016 Silverado that GM sent to the Canadian Truck King Challenge in October was a preproduction model, so the event judges were among the first Canadians to get behind the wheel of one. Unfortunately because it was a preproduction model, it will soon be crushed; it can’t be sold. That’s a real shame, because […] Read more

Rebuilding Big Roy

When restored, the prototype tractor will help Versatile celebrate its golden anniversary

In 1966 Versatile began producing tractors with the G100 and D100 models. That was 50 years ago, so 2016 is the year this brand gets to celebrate a golden anniversary. And it isn’t going to let that milestone pass unnoticed. As part of the celebrations, Versatile has arranged to bring home the most recognizable tractor […] Read more
