Weak spark, valve burnt , rocker adjusted too tight, bad spark plug. Get a compression test done might tell you. My 2c worth.

Interesting!. What are the bugs?

Brakes and such . Mate, you have a classic- vintage car. Some parts are a little hard to locate,but are still around. It's going to cost you far more than the price of wheel cylinders to fit disc brakes to the back, and besides the majority of braking is from the front. If you had ever ridden a motorcycle you would understand this. I did, for 20 years on and off the track and seldom used the rear brake, only with light pressure. You are looking to create headaches for yourself. $80 for wheel cylinders is not that bad. Have you priced a rear disc brake setup,? I doubt it.:stupid: You can pick up a complete disc brake conversion kit for only $900 from Motorsport Auto

Perhaps its a faulty gas pump. It pays to watch the thing when filling. The pipe that goes from the cap to the tank is often rotten allowing gas to escape if you fill the tank to the top. If the fuel was poring out underneath then there would be no surge up the filler pipe to activate the mechanism to switch off the gas pump.

Your car sounds stock. Leave it that way. The stock brakes are very good, and parts are available.

As I said before, the 4x4 toyota brake upgrade is for the front. The calipers will bolt on the same holes. From memory 90mm hole centers. Good quality pads on the standard front calipers is very good though. Are you confused yet.? Suggestion- leave the front alone, until it needs attention. Suggestion-replace rear cylinders. That will be far simpler and way cheaper than trying to fit discs to the back.

Good effort John.I bought my 72 240 11 years ago, and it clocked over to zero when I drove it home. I can still remember 10 years ago, after a major overhaul, inside and out, on my car, putting it all back together and firing it up for the first time in 12 months. I very nearly wept with joy, after all the hard work. Apart from some clutch issue which was my fault, my car hasn't let me down in 25000 miles. They tend to become a loved family friend. Hope you have years of enjoyment from yours.

The front brake calipers can be removed and Toyota 4x4 four pot calipers fitted to improve the front brakes. Vented front discs can also be fitted to improve cooling. As a rule, unless you do performance driving, the standard brakes are very good. Maybe a new set of pads for the front is all thats needed. Motorsport Auto sell kits to do these alterations, or you can gather parts from car parts shops and do the changes this way. On my 72 240 we did a driver training day at a local track and after a number of quick stops the brakes were cooking and not pulling the car up. Having some engineering knowledge I was able to gather parts from PicaPart and put together my own performance front brakes. Toyota 4x4 calipers and vented discs from a Mitsi station wagon. Total cost about $150. If you are happy with the front brakes leave them alone till they need attention. Just check for leaking fluid.

Don't waste your time and money on that heap. Get a two seater 240 or 260 in better condition. Result is much more satisfying and should be worth more. Just my opinion.

Sounds like a job for an auto electrician.Could be a crook alternator.

What don't you understand?

Hi from New Zealand Thor. Nice car well done.

That is a nice looking 260.

Iv'e had similar on my 240. After draining and refilling the radiator it started to overheat. Realised it had an air lock so loosened the engine side hose and purged the air as it was running, at the same time filling radiator with hot water.Iv'e had this a couple of times over the years, and yes, glug glug glug!!!

MSA. Four days from US to NZ .Good enough for me. Tried Victoria British years ago. Waited months for the parts. I havn't tried anyone else and don't see the need to.

I have purchased numerous parts for my 240Z over the last ten years from Motorsport Auto in Orange California, and have found them very prompt and reliable. I don't bother with others.

Could be something as simple as knocking a wire off with your elbow. I have done that:stupid:

Is the fuel smell with a full tank of gas?

Fuel smell in car. Is it when the tank is full. Could be a perished filler pipe?

I have a 72 240 as well and have tried most everything to remove the diff clunk. Mine does it when moving off in reverse as well as forward, which makes me think it's not the front diff mount that is the problem. I put in a diff and halfshafts from a 260, complete with new driveshaft, and the clunk persists. I have double checked all the mountings, and everything is tight. I have concluded after talking to others, that it is a problem with the 240 and 260 diffs. On rotating the driveshaft it is quite easy to initiate a decent clunk, even by hand. There is a lot of backlash in these diffs. :stupid:

We have a stupid law in our city that everyone is bitchin about. We drive on the left, and there are bus lanes on the left where cars are not allowed to drive, until the last 50 metres from the intersection, when you can pull into that lane to execute a left turn. The local authority has people with cameras set up to photograph any offender, who then gets a $150 fine in the post. The question is, how the hell do you tell where 50 metres is, in a car travelling at 30mph- 50kph. I could understand it if they had a painted line on the road or something like that, so that people had a chance to abide by this stupid law.:stupid: Revenue gathering . I would say so, and no, I havn't been caught --yet.

Why was it removed. Did they think it was dumped.?

Wish we were there, instead of shivering in another stinking winter. I suppose this is payback for months of glorious summer.

I use my 240 only once a month for club outings. Havn't encountered any problems. I do check the oil and water before I start it each time. Once a cat leapt off the engine as I lifted the hood. Startled the crap out of me. The car is in a locked, covered courtyard, so no problem the cat getting in.

HELL. Thats a $16000 car down here. Some lucky s.o.b.
