TILLOTSON CARBUREORSTillotson is one of the oldest carburetor manufacturers in the world. Operations date back to 1914. Tillotson invented the diaphragm carburetor, which replaced the float bowl with a rubber diaphragm, thus allowing engines to operate in virtually any position.

This innoviation led the way to an explosion in hand held lawn and garden equipment, including chain saws, brush cutters and blowers. In the late fifties the karters started experimenting and found that Tillotson car-bureors were superior to the float carburators of the day. In the 70’s EC Burt took his years of machining and racing, including motorcycle racing where he is most famous, and looked for a new war to fight. He chose karting. He soon realized the need for a carburator for small engines. He liked the basic advantages of the Tillotson diaphragm designed carburetor. That foundation led to him working directly as advisor to Tillotson LTD in Ireland to create what we have today as a true racing carburetor that is accepted worldwide.

Racing machines need to be maintained and serviced regularly. One part that seems to be neglected is the carburetor, this may be, because a good carburetor continues to work s even though it is getting slower ever so slightly. It eventually comes to a point where you have to adjust it radically different than when the carburetor was new.

All parts work together in the carburetor, but some part need servicing more often than others. Below Is a List on recommended changes

Pump diaphragm , inlet valve diaphragm and there gaskets every three racesNote: one two plate pump stack carburetors if rules allow it is highly recommended to use a .040” thick pump gasket part # 219 main diaphragm and gasket every five races Inlet needle every 5 races if using E-85 or higher ethanol, methanol , Nitro or special mix racing gasoline note: endless you there a issue do not replace the inlet seat as a regular service. It’s not a part that wears , the threads in the carburetor body are very fragile and if stripped can not be repaired.

HW Tillotson SeriesIn 2007, the introduction of the HW series Tillotson® avenger, a new line of carburetors designed specifically for the racing industry. These carburetors maximize the performance of today’s racing engines, with greater fuel flow, more power and more fine adjustment. Built for the CIK KF engines and tuned in some class, has been the dominant force in Europe. Tillotson has built the HM series carburetor for racer in the USA running the Unlimited All Stars class and Jr Drag Racing.

Tillotson Carburetors Tools

Carbureto Pop-off Pressure Tester Instructions:To check the “pop-off” pressure of your carburetor inlet needle, remove the fuel line from the carburetor and plug the tester gauge line onto the cap (Picture #1). Pump the tester up now and watch for the tester needle to drop. When it does, this is the inlet needle’s “pop-off” pressure. a good needle and seat will “pop-off” at the desired setting, drop ½ to 1 pound and hold. a very slow leakage from this hold pressure won’t affect the performance of your carburetor but a complete drop from the desired setting to ZERO on the gauge will cause very poor carburetor performance and must be cured.

Never check your “pop-off” pressure with the carburetor dry. We advise that you fill the line of your pressure tester with WD 40 then when you pump this in, to test the “pop-off” pressure, the needle will be wet and closer to the condition it will be when running. If the Carburetor is all together or on the engine remove High Side Needle. If you determine to modify or change the “pop-off” pressure of the carburetor, remove all covers, diaphragms and gaskets from the main carburetor body. now put about (3) feet of fuel line on your pop-off tester and fill the line with Wd 40 then put the fuel well adapter into the end of the line.

After making the desired adjustments to the inlet tension spring for a change in “pop-off” pressure, you can now check it by inserting the adapter into the fuel well passage (Picture #2). By inserting the adapter into the fuel well passage (o-ring end of adapter down) and pushing with pressure on the o-ring, you will seal off the pressure to the needle and seat for accurate readings. NOTE: It is not advisable to stretch the inlet tension spring or cut off the spring where you have an end that stands up. This will cause inconsistent pop-off pressure in the carburetor when racing.

Adjusting the Metering Lever HeightWith the metering diaphragm and metering diaphragm cover removed:1. Remove the 6 bolts holding the pump assemble on the carburetors.2. Make sure the metering diaphragm and gasket is remove, and any torn gasket is completely clean from carburetor body.3. Make sure the metering lever spring is seated in its hole in the chamber floor and under the dimple in the metering lever.4. Place the EC fulcrum arm height tool across carburetor body casting, as illustrated. Metering lever should just touch the gauge. Slight pressure will bend the fulcrum arm . Lightly bend the needle valve of the fulcrum arm end up.5. Gasket must be assembled next to the body as shown6. HL and HR Tillotson are set from the factory at.085 deep, most gasoline 4cycle engines set at .075” and most methanol engines set at .065” This is one of the most important settings, take your time.

Cutting inlet lever spring (pop-off ) spring properly Start by using a EC spring, most of our springs have double coil on one end of the spring(Pic B) so you can cut one coil off if necessary to lower lower installed height thus lowering your pop off pressure on a given spring. Next, make sure you buy a high quality nail clippers that have heat treated blades (from a beauty supply house for professionals) not the junk at the five and dime store. a good pair of nail clipper will make a clean cut with out bending the wire and leaving a burr(pic C).Never: stretch a spring, it will in time will find it way back and cause a erratic behavior in your carburetor.Never: Cut a spring to leave a dog leg (Pic D) This will cause pop off pressure to be erratic

(Pic A)This type (Single Roll) of spring can’t be cut.

(Pic B)This type (Double Roll) of spring can be cut.

(Pic C)Cut the bot-tom most coil leaving at least one full coil.

(Pic D)Do not cut off all full bottom coils leaving a incomplete or dog leg coil. Never run a spring in this condition!
