Possibly you were trying to adjust the regulator without having air flowing through it. You must squeeze the trigger on the gun and have air constantly flowing through it otherwise the regulator knob is very hard to turn against the pressure inside it. To set an accurate pressure, squeeze gun trigger (while connected to air hose) to get air flowing... then twist regulator knob out (or in the "-" direction) until air flow reads 0 on the regulator gauge. Then start twisting regulator knob the other way until you reach the desired pressure on the regulator gauge. Also make sure the regulator is attached with air flowing the correct way through it. There should be an arrow somewhere on the regulator body which should be pointing toward your spray gun.

Get a fuel pressure gauge and connect it to the rail for the fuel injectors to read pressure.

If the pressure is too low, it might be a bad fuel pressure regulator or pump:

There are two types of regulators used. One has a rubber diaphram sealed at perimeter with body and a piston type. Most likely you have the piston type. Remove body containing piston/ spring mech. Examine piston lip seal. Lip will face toward body of reg. and must fit snugly into cylinder. Make sure cylinder is smooth and is well lubed.
If seal/piston fits loose remove seal and wrap some teflon tape in groove and re-install lip seal /test for snug fit. Notice small metal actuator extending from center of reg. , if it is circular (about 1/8 dia) then there should be an oring of the same size mated/fit into the piston. If this oring is missing it will leak as you describe. Lastly, there should be a gasket or oring sealing outer shell to body. If you have diaphragm type look for holes, tear or shrink too small. Parts are at www.toolpartsdirect.com or Lowes in the plumbing department good place for orings and silicone lube. Good luck

Shifting problems/Tiagra STI Flightdeck


It sounds like the limit screws on your derailleur body are out of adjustment. They are usually small phillips head screws on the body of the front and rear derailleur that limit the travel of the derailleur body on the rear so that the chain cannot get shifted into the spokes or off the smallest cog into the frame. On the front they prevent the chain from shifting off the inside or outside cogs. There are good articles under front and rear derailleur adjustments at this site:http://www.parktool.com/repair/byregion.asp?catid=53 I hope this helps.

Regulator doesn't allow gas to flow to grill . Grill cannot heat hot enough to grill steaks. Gas flows too slowly.


Shut off the gas at the tank and disconnect everything.

Unscrew the plastic cap on the regulator. Inside is a flat screw top that has a single slot or an X-shaped slot. This is the pressure adjustment. It controls the diaphragm that regulates gas flow.

Note where it's set. Use a Sharpie to mark the adjuster on its edge (place a dot there), and make a corresponding mark on the threads next to it.

Next, use a large screwdriver or a coin to spin the adjuster counterclockwise three or four times. Pay attention to the number of turns. Now, screw it back in (clockwise) the exact same number of turns, stopping at the index mark you made.

Next, turn the adjuster two turns clockwise, followed by two turns counterclockwise. The idea is to end up where it was originally set. This action unsticks the regulator's valve seat. Done.

Put the cap back on, hook it all up, open the tank valve, and make fire.

Oongawa!

Adjusting front derailer


Typically adjusting the front derailleur is a matter of adjusting the two adjusting screws on the derailleur. So turn the bike upside down. It should sit on its seat and handle bars. Find the two adjusting screws one will prevent the derailleur from traveling too far out preventing the chain from coming off. The other screw prevents the derailleur from traveling too far in keeping the chain from falling off that way. Now once you have found the screws slowly start turning the pedals like it was being ridden. Move the derailleur out as far as it will go if you see the chain is about to come off adjust the screw. Do same for inside screw. Now move the back derailleur all the way in and retest front derailleur, repeater with rear derailleur all the was out. Hope that helps. Oh, the back derailleur adjusts same way.
