Thread: Gav's 101.

Years ago mine stopped working. Exactly as you describe. I ended up un crimping one end, and removing 5 mm from the outer sheath, then putting it back together. Worked fine then. It was when I was fitting the diesel and shifting the box about.. Hoping not to have that issue this time as will have to run a 90/110 speedo to suit the LT 230... (Hoping 255/100's and 4.7:1's will work out similar to 235/75's and 3.5:1's)!!

I don't suppose you can snap some pictures of it while your fixing it could you Gav? Mines naffed but not actually sure how the thing is supposed to be so no idea if it can be rescued or not. I'm sure I'll need a working speedo to get over pits too when the time comes.

Will do Stuee. What pics do you want - cable, speedo, both?

Well, just got back from a good 'shake down' drive. Went for a run with Fraser130 - did about 200Km mostly on freeways, but some City and Suburban driving too. The Weather was terrible - blowing a gale. BOM shows wind gusts up to 80KPH and average wind speed of 50 odd in some of the places we have been. In general, it did a great job, but I have found some small issues that require attention. Here is a list of things I've discovered today.

- With a 50KPH tail wind, a 101 is surprisingly quick.
- With a 50KPH head wind, the overdrive is redundant.
- The OD has an oil leak from where the selector shaft goes into it.
- With OD engaged, it is most comfortable at 95 to 97KMH (GPS speeds shown here as the speedo,is still busted.
- At 95 (with OD in), the engine is doing a tad over 2,500RPM.
- At 95 (with OD out), the engine is doing just over 3,100RPM.
- My back didn't pay up at all in the original seats which I thought it may do if I spent more than half an hour behind the wheel, so I now know I will be keeping these original.
- At full throttle, The engine pings a bit - more on that below.
- I love this vehicle more every time I drive it.

As mentioned above, at full throttle I get a bit of pinging in the engine. Not sure if this is a timing issue or something, but the engine runs and starts beautifully as it is, so I am a birth loath to change anything, but I'll need to check this. What is the compression of these motors? I am only running normal unleaded in it - do I need to be running Premium, or is the pinging something else?

Also, I'll post a pick of our coffee stop - it was a little unusual and we got some funny looks, but was great fun.

But the thing I mostly got out of today, was that I'll now sure it will do the run up to Northern NSW and back in October with ease.

Cheers - Gav

Mainly after pics of both ends of the cable, but will take a pic of the speedo without the cable in it if you have that. I have one good end on the cable and I suspect that the other end has been left behind in the speedo, but whats speedo and whats cable I'm a little unsure so don't want to go ripping things off the back of the speedo if they are actually part of it.

Gav - the standard engine is low compression so if tuned correctly should not ping on 91 octane. If work has been done on the engine at some stage HC pistons could have been put in so maybe needs 95/98 octane - however the previous owner never mentioned it to me in discussions so I assume it is standard.

He did tell me about his great fuel consumption which if to be believed was better than I could achieve - maybe it has been tuned to run lean burn over the usable rev range and is too lean at higher revs.

Until you sort this I would not be driving it under heavy load or you could burn something out. The engine can take a lot of advance - in the order of 10 degrees btdc without pinging on 91 so a check of mixture and timing might help - have you topped up the carby dash pots because if dry can change mixture (as can oil weight).

Thanks Gary. Once I heard that noise I backed off and haven't been running past about 75% throttle since.

It is in need of a good tune up - something I have yet to look at. The previous owner didn't do too much to it in the 12 months leading up to selling it, so it is certainly due for some work in this department.

I've never had much luck tuning these carbys on my own when I had them on my 86 Rangie, so I'll find someone that can do this properly. The 2 people I knew that could do these perfectly have both since past away, so I'll have to do some homework there.

As for fuel economy, I'm yet to run any numbers on this, but after todays run of around 200KM - looked up our route on Google maps as I had nothing else to gauge it off, I have used just under half a tank - according to the fuel gauge - which is a bit of an unknown quantity, but does sort of sound right I suppose. Even when I get the speedo working, it is reading faster than what I am travelling at, so it will show more KM than what I'm really doing, so maybe that is the reason for the claimed fuel figures?

Who knows, but I just start and finish my trips at the servo, and I don't really look at how much goes in - maybe I don't want to...

So, here is our effort for having a coffee while out and about in the 101...

It was Frasers idea, he wanted to see if the coffee machine would run off his generator, so we threw them both in the back. Not sure what the locals thought but we got some strange looks. It was a bloody good coffee as well, better than a lot of places make and charge you $4 for.

Classic. Just need to repeat on a busy cafe strip
