Air is leaking out of regulater

Implies carburetor low speed fuel circuit lean. Increase low speed fuel/air.

Initial setting is 1 1/2 turns. Increase idle speed enough to keep the engine runnning so a proper adjustment of the low speed air/fuel mix can be completed.

Basic rules; Always adjust low speed a/f first, then open throttle and adjust high speed a/f. Any low speed adjustment must be followed with a high speed adjust. Error on the rich side for high speed. Allow engine to reach operating temperature for final adjustment.

Other potentual issues, fuel quality, fouled carburetor, old impulse diaphragm (carb), carb to engine intake gasket leak, crankcase leak.

Removing tines makes it easier (safer).

rebuild regulator

I Have a BRC-200 as well. On the air outlet there is a red twist top to adjust the amount of air it stops at. Turn the red dial in (down) and it will increase the pressure. Turn it out (up) and it will decrease ithe pressure before it stops compressing. If you go to hig, the valve will blow (been there lols). Mine is oil filled btw...

Assuming your talking about the regulater it is repairable. first remove from comp. disassemble bottom needle valve and seat by simply unscrewing round cap on bottom of reg. check to see if the valve is hanging up . normally due to air comp. oil blow by. clean lubracate and check for o ring or seat damage. remove 4 screws from top of reg. first loosen adjustment knob to release spring tention once you remove make sure diapham isnt torn or damaged clean lub. reassemble bottom valve push the needle down to make sure it releases and works properly. reassemble top diaphram spring adjustment and cap test if the through cleaning doesn't work and in my experiance it does 85 % of the time you can buy a rebuild kit for it. hope this helps it is a simple repair

check air tank drain valve located on bottom of tank, if it is not leaking try adjusting air pres regulator (large black knob close to air hose connection.) the knob when turned in will increase the tank air pressure, if knob wont turn check that lock ring on bottom of knob to make sure it is disengaged. also check for air leaks in all lines and connections

Check everywhere for air leaks. If it has a carburettor start the car and spray butane gas around it, if the revs increase then you have a leak somewhere as it is sucking in this extra fuel.

You either have a severe air leak in the tank (possibly the safety valve is leaking), or the compressor valves require service. Remove the cylinder head to check the valves. good luck!

Sounds like there's a leak in the fuel line, or the evaporative emission system is flooded with gasoline and is purging it to the atmosphee.

Replace the regulator

hi
check the all vacuum pipes is their any leaks.
