Carburetor cleaning and fuel system work for older vehicles: rough idle, hard starting when cold, stumbling under acceleration and flooding. Call 704-842-9774 and tell us how it runs.
We work on the vehicle where it is parked, and tell you honestly when a clean will fix it and when it needs a rebuild instead.
Clean Or Rebuild, Honestly
A clean solves varnish and blocked jets. Worn throttle shafts and perished gaskets need a rebuild, and we say which it is.
How Does It Run?
Call 704-842-9774 and describe it: hard cold starts, stumble on acceleration, rough idle or a smell of fuel.
Confirm the fuel system is the cause rather than ignition, check fuel delivery and the filter, then clean the carburetor, set it up and road test.
1
Tell us how long the vehicle has been standing. A car parked for months has a different problem from one driven daily that has gradually got worse.
2
We check spark and compression first, because a misfire from a tired ignition system feels exactly like a fuel problem and cleaning a carburetor will not touch it.

Jets and passages cleaned, filter replaced, float level and mixture set, linkages freed and adjusted, then run and road tested to confirm the idle and throttle response are right.
Modern fuel does not keep well. A vehicle left standing for months gets varnish in the jets and a gummed float, which is by far the most common reason these calls come in.
Nearly all the carburetor work we do around Charlotte falls into two groups. The first is classic and project cars that spend long stretches parked, where modern gasoline forms varnish in the small passages and the vehicle becomes hard to start and unwilling to idle. The second is older trucks and small engines in regular service where the jets have slowly clogged. Heat matters in both cases: this past summer the city logged 72 days at or above 90 degrees against a normal 44, and underhood temperatures that high encourage fuel to percolate in the bowl, which is why a warm engine can be harder to restart than a cold one. It is worth checking the ignition system before assuming the carburetor, because weak spark produces very similar symptoms.
A carburetor that has sat through a season is usually cleanable rather than scrap, which is a far cheaper outcome than the replacement often suggested. The work sits under Auto Repair Shop Charlotte.
A vehicle running rich for a long time tends to take its exhaust with it, so the two jobs frequently arrive together. Repairing the pipe side of that is covered by Auto Exhaust System Repair Charlotte.
The fuel system calls that come in most often around Charlotte, and what each usually turns out to be.
A vehicle that ran fine before it was parked for the winter. Varnish in the jets and a gummed float from fuel that sat too long. A clean usually sorts it, and fresh fuel plus a stabiliser prevents a repeat.
A stumble when the throttle is opened quickly. Typically the accelerator pump circuit, either a perished diaphragm or a blocked passage. Straightforward once it is actually identified.
Hard restarting when the engine is already hot. Fuel percolating in the bowl after a heat soak, which Charlotte summers make far more likely. Heat shielding and correct float level both help.
Common questions about carburetor work: what a clean covers, when a rebuild is needed, and how to keep a stored vehicle healthy.
1
Older carbureted cars and light trucks, classics and project vehicles. Fuel injected vehicles need a different approach, which we also handle.
2
Often, if the cause is varnish or a blocked jet. Worn throttle shafts, perished gaskets or a damaged float need a rebuild, and we tell you which before starting.
3
Use fuel stabiliser in anything that will sit more than a month, keep the tank close to full to limit condensation, and run the engine long enough to get warm rather than just idling it briefly.
4
Easily. Weak spark, worn plugs and tired leads produce symptoms almost identical to a fuel fault, which is why we check spark and compression before touching the carburetor.
