General Lee: For such a TSP platform, indeed, is the test of the ability to integrate the same time, just She always has been mentioned in the business platform is a completely independent intellectual property platform and our platform is t In the shape of the design, the Core wing broke through the traditional appearance of the other models, the Core-wing sense of movement and high-level sense of the high degree of balance, which must be improved, both in the interior styling
Maximumperformance cannot be achieved unless the carburetor is wide open when thethrottle is pushed to the floor. Consequently, throttle opening should bechecked regularly, immediately following any major changes in the enginecompartment. Maximum airflow cannot be achieved if the throttle plates do notreach the wide-open position, or if it is pulled past wide open. The throttlelinkage should operate smoothly without binding and should be free ofobstructions that may cause the carburetor to stick open. An auxiliary returnspring MUST always be installed to insure that the throttle positively closes.It may be necessary to install a stop to prevent the carburetor from beingopened too far and to prevent damage to the linkage. Take your time and set thelinkage up right! Tuning linkage on sideways mounted tunnel ram carbs willtake longer than a single 4 barrel. ClimateChanges and PerformanceChangesin air density due to changes in temperature, barometric pressure, and humiditywill have a direct impact on engine performance. As the air density changes,adjustments to the fuel mixture are often necessary. These factors can changefrom afternoon to evening. Everyone knows the engine will make more power atnight when the air cools. The cooler, denser air carries more oxygen per cubicfoot and thus support the capacity to burn more fuel. The weather conditionsmay not change enough from afternoon to evening to require mixture adjustments,but adjustments will certainly be necessary as the seasons change. Traveling totracks in different climates or at different altitudes may also cause a needfor fuel mixture adjustments. These factors cannot be overlooked when tuningfor best performance. TuningWith SpacersSpacersand plenum dividers provide an easy way to change the configuration and thecharacteristics of the intake tract and the relationship it has with thecarburetor. Adding a plenum divider to an open plenum manifold can help keepthe left to right fuel distribution balanced for oval track applications Thisis especially helpful on alcohol engines. Usingspacers between the carburetor and intake manifold can produce dramaticresults. The use of a four-hole spacer can improve low end to mid-range byhelping the carburetor draw and atomize fuel. An open center spacer increasesthe plenum area and can benefit the mid-range and upper rpm power. It is notuncommon to see combinations of spacer types or stacking of similar typespacers being used. Theactual results from any spacer or combination of spacers can only be measuredduring a test and tune session on the specific engine combination being run.This information can be a very useful tool when tuning to find the besthorsepower or to change the power characteristics to suit a specific trackcondition. RoutineMaintenanceForconsistent performance, a carburetor must be kept clean. Spray the air bleedswith carburetor spray or WD-40 every week. Air bleeds become clogged from dirtand dyes in the fuel. Clogged or dirty air bleeds can cause a stumble or ahigh- speed miss in an otherwise perfect carburetor. If you are putting the carup for the winter, use this little trick. Spin the engine over with theignition off and the throttle open and spray of WD-40 liberally down theventuri will leave a fine mist of protection on the valve seats and cylindersto prevent rust. Finally, your carburetor should be rebuilt at least once ayear and more frequently if itýs operated in dirty conditions. AlcoholTipsApplicationsrunning alcohol require additional maintenance beyond that of a gasoline fuelsystem. Alcohol, being extremely corrosive, should not be left in the fuelsystem or carburetor for an extended period of time. Proper care includesdraining and flushing the entire fuel system, usually with gasoline. The mostcommon method is to drain the system and add gasoline to the fuel cell allowingthe pump to draw fuel through the lines and to the carburetor. Alcoholcarburetors are much richer than gasoline, so when the engine begins to idleand die, the system is pretty well flushed. If your sanctioning body allows theuse of fuel additives, always use an additive that lubricates the fuel systemfor protection while racing.Find out more about Toyota 4AF carburetor by visit miparts.com.
