Glynn, being a hero as always! Top work dude I'm sure TBR will be able to sort you out. Just wanted to add that although I reckon there is very little chance you will need a new engine, if you do decide to, 40mph is still 40mph more than mine will do, so would be interested in offsetting some of the cost of a new one..
Update: @burnzdog definitely has a 1600 engine, I've checked the heads, engine runs well and quietly, top temp was 112 degrees. However the throttle linkage was completely seized up and the twin carb linkage was only opening to 1/2 throttle. The throttle bar brackets were seized up solid and had to be drilled out, sorted all this out, cleaned and greased the bar and linkage, adjusted carb linkages and generally fettled, goes like stink. does 70 now instead of 40. Also fitted some spare air hoses from fan outlets to heat exchangers. However on the way home it appears to have got excessively hot? I suspect some other issue that has reared it's head now that it goes faster? My thoughts are maybe that the heater pods are seized shut and this is not allowing the hot air to escape now we have fitted hoses? Whereas before the hot air just went back into the engine bay causing only mild overheating? With this in mind he's removed the pipes and is driving home at 55mph. We await more news........
He's running home but it stalls at lights. I still think it needs timing and carbs resetting now that they open properly? Any advice welcome, @zed @Paul Weeding?
We just tried it the once to see what it'd do, 30 secs at most. Appears to be heating up on the way home, ie over long distance. He's still going but says it's hot, I still suspect the heating/cooling as this wasn't working at all.
yeh are the cables attached n has it got thermostat n all tins fitted ? Your a star thou even if your future misses thinks you need a windmill
Well done that man. Heater tubes a bit of a red herring, I think. With the heater flaps in the closed position, hot air is designed to spill from the vents on top of the heat exchangers to the outside world. Need to look elsewhere, I think. Thermo & flaps working properly?
Nope, tins missing, pipes missing etc etc. I think it didn't overheat before because it never got above 1/2 throttle or 40 mph. Nothing is insurmountable and he left here a lot happier than he arrived. I'm tempted to get him to come down next weekend when we'll have the assembled might of @poptop2, @baybirmingham and meself. then we can get the rest working for him, he's a really nice geezer.
I thought that too but the only thing we did to cooling was to fit the pipes from fan housing to heat exchangers. Having said that, beforehand the bus would only do 40 on 1/2 throttle so I suppose it couldn't really get THAT hot.
Yes! That has been sorted. It runs really nicely, no popping or banging, ticked over fine when at normal temp. Just seems to be overheating on long fast runs.
mine gets quite hot on long run , but very hot if fast ,it does 70 too , i bet hes chuffed as said well done , theirs not many like you out their
Timing or more likely top end under fuelling... Trip to the rolling road to get the carbs set-up/checked!!
Could be, he said it was done by his local man but my faith in him has wained after the 1300 claims and him not noticing the carbs didn't open. He had no timing disc and I'm used to type 4's where the timing mark is already there. It looked pretty good to the eye though and it ran really well on initial test. My money is on timing and cooling combined, nothing major and I hope it gets sorted, he's a nice bloke.
