The stock setting for the throttle screw and air screw is one and one half turns outward from a LIGHTLY seated position. Go to babbitts sports center.com and you may be able to see a parts diagram for your bike and get some parts as well. Click on buy OEM parts. Your bike is really old so I can't guarantee it will be listed. I am not at my home computer so I can not check for you at the moment. Check to see what main jet is stock in the bike. Someone may have played with the jets.

Why my s430 will run and idle but dies as soon as squeeze the trigger even if I do it slow? The primmer bulb was bad so I changed that but still does the same thing?


Carb is in need or a cleaning and rebuild. I would suspect the diaphragm is bad. You can get a rebuild kit with all the gaskets for most carbs for around $10. There are some that gaskets are not available for and you would need to replace the entire carb. Carbs run from $15 to $30.

84 f150 carburetor out of tune


When you get a rebuilt carb you have no idea what the
applications are for

I suggest you rebuild your own,
that way you have all the settings
& experience when your done

I think the float needs to be set correctly
& maybe the pump if there is anything for that
external

You have to have some knowledge about basic
adjustments of air idle screws

Start about one turn out from seated & then use a
vacuum gauge to get the highest reading & then go in
a 1/4 turn
Can use a tach also or both,then reset the timing

I would have all 3 on motor at once

When done you set the idle screw with air cleaner on

Both master cylinders leak fluid


This is unusual as I ride a 1994 model and have yet to have to rebuild the master cylinders. But, if they are leaking, it's time for a rebuild. You can buy the rebuild kits either through Harley or aftermarket. Simply disassemble the master cylinders, lightly hone the bores with a flex hone, and install the new kit. Make sure you use the correct type of brake fluid and do not mix different types of fluid. This may be what is wrong with your master cylinders now, mixed brake fluid. If it looks like someone blew their nose in your master cylinders, that's what happened. In this case, once you get the master cylinders rebuilt, you need the bleed the system throughly to clean out the calipers and hose as well.

Good Luck
Steve

When i press pedal down fluid is squirted back into the resvoir not to brakes


Time for a new master cylinder for your car. You can purchase a rebuild kit ... based on my experience, you are better off with a genuine rebuilt device as special tools are needed to rebuild it yourself. For the couple extra bucks you will spend, you will safe time and money.

Thank you for your visit today. I hope you find this information helpful.

Should I rebuild my Ford Bronco 351 Windsor Holly 4 bbl carb or replace it with an Edelbrock carb?


In all my experience, if you know how to correctly tune a edelbrock then go with that, but, holley has outstanding carbs that can muster up to an output of 1,200hp. it would be much cheaper to et a rebuild kit from say, o'reillys, 20-45 dollars depending on which one you have.
I have a 1985 Bronco 351w 4x4, i just rebuilt my holley and she runs smooth

I need engine rebuid diograms for a sthil fs55 strimmer


you dont need a diagram. i used to work for a place where we rebuilt all kinds of gas and electric power tools and etc.. my experiance from trimmers the exact same way you take apart you put it back together. and you dont rebuild the engine you replace the muffler, the sensor, the spark plug, the rotor,and you can really take apart the carb.and clean it and put it back on
