Is there anything missing in this picture ?
Hi,im having some more problems with my 1980 230 g 4 cly petrol , the problem is getting it to run smoothly ive taken a picture of the carb and there is obviously been something taken off but it was like this when I got it any ideas whats missing ( I cant find any pictures of a carb etc to see whats not there ) is whatever is missing needed or can it run ok without the missing part anyway hope the pictures work ,cheers ,Don
Hi Don,
Nothing like my 1987 230. My carb is completely different, and on the other side, as is my battery, sorry. First time I realised they changed the 460 G that much.
Hi
PM me your chassis number and i will try to print and fax /post some parts pictures for you to see if i can help
identify things...looks like you have the old '80 m115 engine as against a '87 m102 jd refers to. maybe LHD ?
aswell so battery has swopped sides?
Have you done anything to the carb? I have run twin versions of the Stromberg 150 and 175 carbs on various Triumphs
and had a few issues with split diapragms in the carb causing irrattic running issues
Thanks
Gav
Hi
Just had another look and its a shame i cant quite read the chassis number on the plate its just at the wrong angle and too much glare on super zoom (460 217 17 000554 at a guess which would make it LHD and early!!!!)
The loose vac pipe you are holding on picture one could have something to do with it? Just in the back of the shot to the back left of
the blue insulated spade connector is what appears to be a blanked of vacuum connection on the manifold with a new jubilee clip
on it? it maybe should be connected there but is only a guess. also the fuel? pipe out of the side of the carb and back in again in a loop looks odd too? could have a replacement carb that was originally one of a pair? i guess with the age anything could have been replaced!!!
Thanks
Gav
Hello again
I love a good game of guess what the odd pipe is?
In the second and better in the third picture there is also an odd pipe to the left with what appears to be a 8mm bolt jammed in it and a jub clip round it?
But more puzzling just to the left of that hanging down and touching the manifold looks like the thin black end of another vac pipe
that looks like it has been cut or melted on the end and looks the same colour as the pipe on the other side of the braided pipe you are holding in pic one
I could play this all night!!!!
Hope some of these observations help
Gav
One last go for tonight
Just logged on to MB EPC
The diapragm for the M115 engine is part number A0000710826 and off memory was only a few quid from the dealers but its a long time since i have sold one!!!
Its a long while since i have seen anything in the dealer with a carb on it at all but apart from your un connected vac pipe the only other common faults were any other split vac pipes or rubber joints that had gone soft and collapsed under pressure (sucked closed) and the diapragm the only other common irattic running maledy was the spacer plate between the carb and manifold that used to break up and flex and allow air in
Good night all
Gav
On initial reaction I would have said that the vacuum pipe should be connecting to the distributor advance module, but looking through the limited information I have, it looks like it makes up a circuit of air intake heating system, attaching to the air intake housing. I would block the end up by screwing a bolt in it just like you have other hoses blocked off.
If you have been driving with hose as is, blocking the hose of may change the fuel mixture and driving characteristic a little, in which case the carb. will need re-adjusting.
cheers,
Hi Don
according to the vin number above the engine should be an M115-973 and the G' was built August 21st 1979 in Graz Austria at Steyr-Puch .....
Hi Don
Fixwin is right with build date and engine type and i do have the full engine number to hand.
The parts pictures on these are a bit primitive and the pipe work is shown on various different pictures.
My interpretation is as follows and as pistonhead stated in an earlier post that one pipe comes from that part of the carb to the vacuum advance which the pictures do show as the thicker rubber pipe. The parts pics show the outlet next to that is just blanked off upto a certain engine serial number? (which your serial number is). Another parts pic of the inlet manifold show three connections in the middle. (one valve in your pic with the blue elec conn and two at the side. one of these ( the one that on your engine is blanked off )shows having a vac pipe running from it around the back of the engine to where the pipe that appears cut / broken comes from.
If you need copies of the parts pics i can post or fax them to you if you PM me your details i will forward them.
If it was mine i would try connecting the rubber end with the loose cut / broken end and see what happens as you can always reverse
the layout if you do it one thing at a time.
If that is no better i would try swopping the blank end on the manifold with the pipe in question on the carb and then connect the loose / broken pipe together.
I will try to find a vac pipe layout / diagram if i can.
Thanks
Gav

Don.
I have found some pictures of the connections on this Stromberg carb.
On my M115 engine the connections are made in the way the pictures show and everything works perfectly, so maybe it will be of some help.
If you want some more info, please send me a pm.

cheers for the info ill print off the pictures and compare with mine ,thanks,don

thanks for the replies it is a left hand drive, I think the id number without going to look as im at work and the G is 45 miles away its on the registration certificate its 46021017000983 Ill check when I get home on the chassis plate ill also get the engine number thanks ,don
