Thanks fellas. Engine is running real good now. Getting water flowing through the base again to warm it up made a huge difference.

Hi. Looking at your pictures again Scrubb the water line must go to then auto choke, which has been removed from this carb. Where does it go to once it's been through the auto choke. Ta.

Yes - one flasher unit does both sides. If it's orig yours is probably an old mechanical one. It's a cylinder about 30mm diameter and maybe 40 - 50 mm long if it's an old one. Replacing it with a new one won't hurt - it'll be tucked up under the dash somewhere. Turn the indicator that goes on and listen for it. Will just be plug on terminals. Normally one side stops flashing if one bulb is out - if both bulbs are OK like you say, then yeah, I'd be cleaning up the bulb terminals and any earth wires you can find. I guess check that they are both 12v bulbs too - someone might have stuck a 24v in there.

Thank you. Looks like the vacuum secondary isn't hooked up proper. Line 4: where does the other end of that connect to? And yes, the water line coming from number 1 - it's a different diameter than the heater hoses and any fitting I can find - so help on this would be muchly appreciated. Ta. Bruce

Fitted a carb lot and mr forklift is running shitloads better. Still would like to know where all the vacuum lines went, and also the water line. Water enters the base of the carb and out through a line by the idle jet. Where does that water line return please? Ta. Bruce.

Yes, some help would be good. Am picking up carb kit today. If you could tell me where the vacuum lines run to that would be awesome. Thanks. Bruce

Hello. Hopefully there are some photos below this. The first picture shows a blocked off vaccum line coming from the manifold directly under the carb. I think this one was used for the hot / cold flap thing. The other line you can see going off to the left goes to the vacuum advance on the dizzy. You can't see it, but at about the same height there is another blocked off line coming from the left side of the carb behind what is an extension of the throttle shaft, presumably if this was set up as a twin carb. (Which for a while made me think that if this was meant to be one of two carbs, it would be running real lean - dunno though, it seems to be about the right size for this engine -28C which means 28mm primary, and it was listed in the big book of carb kits for this engine. I'm happy to be told I'm wrong) Both the second and third photo show a crimped off tube coming from the top of the carb. Where did this one go?? They also show a line from the rocker cover which enters the back of the carb. Not shown is a short line for the vacuum secondary. The pipe on the inlet manifold has also been blocked off. Note - the plunger has been disconnected - I'd just taken the top off to check the gasket shape to order the carb kit. Also missing is the auto choke. It does run better once it is warm, but still pretty crap. The forklift doesn't have a brake booster nor the original air filter cover.

Have been trying to add a picture. I cannot find the 'choose file' button at the bottom of the text editing box. I found the 'more reply options' button OK, which brought up a few cool looking symbols, but no 'choose file' button. Help

Close but not the same. How did you get a photo into your post coz I can't? Not by cutting and pasting anyway. The line coming from the top of your carb exiting towards the rocker cover. Where does that go? (My carb has a pipe exiting at same height but from the opposite side of the carb that has been blocked off). Is there a line connected to manifold vacuum anywhere? The line draped over the rocker cover - it looks like it continues down to enter the manifold below the carb on the wheel guard side. I guess this must connect to your air filter - is it controlling a flap of some sort so is effectively blocked off, or is it open to suck all the time? While your carb is different enough from mine to be different it might give me some clues. Thanks heaps. Bruce

I have a 4G32 engine (Mitsi) with a twin barrel Aisan carb with a vacuum secondary on it. As well as Mitsi engines, this carb was apparently in Toyota's too. (Model of carb is a C28MA, or MD-006219) Can someone tell me where the vacuum lines / hoses from the carb should go. Please. If you have a early 80's Mitsi Lancer, L300, etc with a 4G32 it likely has this carb - I can't find a vacuum line diagram anywhere on the net or in manuals in the library. I suspect that there should be a line going from the inlet manifold to the carb to open the power valve- both the inlet manifold vacuum pipe, and several vacuum lines on the carb have been blocked off (it's in a forklift so no brake booster or other fancy stuff - the air filter housing is not standard - possibly it had a vacuum line going there too). Possibly if there was a line going to the air filter housing this should be open, and not closed off. I also want to check that the ignition vacuum advance line is going to the correct place (ported vacuum). The engine was fitted in a friends forklift several years ago, and has apparently never run well - will rev if you open the throttle SLOWLY, but you can't 'blip' the throttle. I have a kit for the carb coming, but rather than then randomly playing around with vacuum hoses, if you have a diagram I can't find, or can look under the bonnet of a standard vehicle and tell me where things go it will be greatly appreciated. Thanks. Bruce

Hello. A friend of mine has a 4G32 motor that was put into his forklift a few years ago. Apparently it has never run right. I have just done leads (one of which had worn through the plastic casing), points, coil and condenser. Plugs, cap and rotor look OK. Won't rev at all when cold. Will rev when warm as long as you build the revs up slowly - i.e. if you put your foot down to give it a quick brrm brrm it splutters like mad. Sounds like big fuel miss to me. It has a twin barrel Aisan carb on it with a vacuum secondary. I have some photos of it but can't upload them here. Only numbers on it are '4H 8' which apparently is a date rather than a model code. Question time. Is it the correct carb for the engine? Anything particular I should know about them? It has a couple of vacuum lines that have been blocked off - should any of these be connected to open or manifold vacuum? Anyone know who carries carb kits for these things? Any advice in general? Thanks. Any help greatly appreciated. Bruce
