Question about Saito FG30(180) 4Stroke Gas Engine AT

Open Question

FG30 setting the carb Please tell me the procedure the manual is a bit confusing. I have the ls needle about a 16th open past the 4.15 turns (asper instructions) the hs needle set to 8300rpm with a 17x8apc. The trancition from idle (2100 which is not very stable) to full is not without misses. I don't know if I should lean out the Ls past the 4.15 the fuel is 91 octane and the oil is as per Satio. And what should the idle be? Thanks, Noria

Why does my Komatsu FG30-11 Forklift not have a year on it?


The serial number will fall in a range ie; # bla bla 1272 thru 1479 were all built in 2005. The dealer can tell you by giving them a model and serial number, ask for someone in sales.

Regarding the honda 1983 vt250f; it requires the fuel intake needle to be set, can you tell me how many turns is generally required, and if the needle is over tightened does this require re-synchronisation...


Usually around 2 turns +/- 1\4 turn.
make sure they both are the same.
syncronizing sets the carbs to open the same amount, shouldnt be necessary to re sync after setting idle jets, unless they were last synced with the idle screws set differently

What are the settings and which jet is high speed adjustment for Homelite Inc. vac attack blower EM08652-01


Hi Roseann, newer 2 stroke engines for the past 6 or 7 years have changed to newer carburetors, and some of them don't have any adjustment needles at all, or just 1 adjustment needle adjust. Without knowing how old your Homelite is or what type of carb you have, I will assume you have adjustments. If you look carefully at your carb, next to each needle you will find the letters F or H, F is the fast speed adjust needle and L is the low one. In general the L or low speed needle is the one closest to the motor. To adjust them you turn both the H and L needles in (clockwise) until lightly seated (so no damage is done to the needle or the seat), now you turn them both out (counterclockwise) 1 turn. You should be able to start your vac with these settings. Only minor adjustments should be required if any at all. To adjust the low one with your engine running at idle, turn in just a little and notice if any difference, if not turn a little bit more until it starts to run rough, now bring back to the position you started with and now turn it out (counterclockwise) in small turns at a time until it starts to run rough. When you do this remember the position of the needle (how far in and how far out) and adjust to the needle to the middle of those 2 positions. Do the same with the H or high needle. At the top of the carb where the throttle cable hooks to the carb you will find a screw that is to adjust the idle speed by adjusting the throttle position. You can adjust that screw at any time to get the idle speed you want.
I hope this is a bit helpful to you. All the best and good luck. Any questions welcome.

I am leaking gas through the over flow hose on my 1997 Dyna wideglide i had to turn the gas off and run the engine tell the carb was out of gas to stop it from leaking but if i turn the gas on it starst...


It sounds like you need a new needle in the carb. The fuel level is regulated by the float which opens and closes the needle in it's seat. If the needle is worn or damaged, it will not completely close. If you just inherited the bike, I would believe that the bike has been sitting up for a while. I'd have a competent mechanic remove the carb and go through it. Clean it out on the inside and put a new needle valve in it. This job is a bit too complicated for me to recommend that an amateur can do it. If you wish to try, I'd purchase a service manual. It's too much for me to type here on this forum. Sorry. Good news is the needle valve only costs about $25.

Lawn hornet fires up from 2 or 3 pulls, runs for 2 seconds then needs a minute or 2 before it will do the same thing. fuel is 40:1....DMac


Before doing anything check the carb fasteners to make sure they are properly torqued as air could be leaking in making the engine not run right, also check the air and gas filters, fuel lines and anything obvious also as a possibility they might be the problem. If anything obvious like that does not work, this could be a carburator ajust problem. Many of the carbs on grass trimmers in the past few years do not have adjustment needles, everything is ported inside the carb. So without knowing anything about your machine and if you have adjust needles this is the basic procedure for adjusting. The 2 needles might completily be out of adjustment, so turn them in ( clockwise) until lightly seated so the seat is not damaged, now turn the 2 needles counter clockwise 1 turn. This is the basic adjust for most carbs to start and run, now make the adjustments. Turn the low speed needle about 1/8 of a turn at a time counterclockwise to let more gas in and try that up to 1 turn (always remember the start position before any adjustment is made). If that does not work return to start position. Now try the high speed needle with the same procedure. If that does not not work, try adjusting both at the same time. If nothing works you probably need a carb overhaul. Maybe only a cleaning or a carb kit might be needed. I hope this helps you out a little. Best regards and good luck.

Gas is being mtxed with the oil


This typically happens when the needle and float are stuck open. The fuel from the tank then runs through the carb and into the cyliners, down past the rngs and into the crackcase to mix with the oil.

You may have something stuck in the needle and seat or a dirty carb. If the unit has been setting a long time you may have varnish in the carb and you might need to replace the part.

Remove the float bowl nut and then the bowl of the carb will come off and you should be able to tell what you have.

The sump overflows even after I changed the float needle


The original Keihen carbs that come on Harley's are notorious for this problem. They've been a problem since they first came out with the carbs back in the mid '70's. Someone makes a special tool that recuts the seat in the carb but the tool cost over $100, far too much to spend to repair a single carb.

Make sure the needle is a good OEM needle, make sure there is no trash in the seat, and you've got the needle attached to the floats properly. Are you setting the float level in the proper manner? The late model CV Keihen carbs specify that the float has to be set to a certain height while sitting on an angle of 30°, I think. The procedure is describe in the service manual but I don't have the book right here in front of me but I do know that it must be sitting on an angle when you set the float. I made a special tool out of wood to do this with. That's why I don't remember the angle. I made the tool and I simply sit the carb on it to make the float setting. Since I've made the tool, I no longer worry about the angle, it's built into the tool.

One thing you could do is set the float level about 1 mm lower. Sometimes, this puts a bit of extra pressure on the needle and helps. I wouldn't go any lower than that though.

Good Luck

Petrol in my engine oil chamber why


If you're getting fuel into your oil, your fuel delivery system is leaking. This problem is most common on carburated engines. The needle valve is not seating properly and when the engine is stopped, the carburator is flooding and the fuel is flowing into the engine. Once it gets into intake manifold, it seeps past the valves into the cylinder. Then it seeps past the rings into the crankcase contaminating the oil. If your bike is fuel injected, the same thing is happening because the fuel is pressurized by the fuel pump and your injector(s) are leaking fuel into the engine.

On a carb equipped machine there us usually a petcock to turn the fuel off with. You can either turn the petcock off each time you turn the bike off (a good practice) or you can have the carburator repaired. Some late model bikes have a vacuum operated petcock that automatically turns the fuel off when the engine is stopped. If your bike is equipped with this type of petcock, the petcock could be defective or is positioned in the "prime" position. If you go into the carbs (I think your bike has two carbs), replace the needle and check the float height setting according to the manual in both carbs.

If your bike is fuel injected, these devices are usually not easily servicable, simply replaced if they malfunction. You could try adding a bit of fuel injector cleaner designed for automotive use to your fuel. It may clean the injector (or needle in the case of carburators) and solve the problem. Otherwise, I'd probably take the bike to a repair shop.

Good Luck!

Will not tick over how do i set up the carb for this and normal running.


Most carbs are the same. Close both the high and low needles. (Note: Do not overtighten, you can damage needle.) Open them up 2 full turns. Start the engine and let it warm up. May be a little tough to start if you have removed carb and rebuilt. With engine running pull throttle to full capacity. Now close the low needle slowly, listening to the engine. When it starts to get lean you will hear the rpm start to go back down. Make sure you stop at the most optimum setting. At this point open the low needle 1/4 turn so as not to have too lean a mixture. Please note that the engine must be warm in order to get the right setting. You may have to do this a couple of times to get it right. Then move on to the high needle and do the same thing. Once you set both needles it should be fine.
