Re: Variable idling 1275 tuned Marina engine
I thought to have checked most other things, yes. I suspected a vacuum leak or a secondary air intake somwhere as you do also. What bothers me is the thermal correlation. If it’s a vacuum leakage that increases with temperature would mean the issue must be in a region that warms up together with the...

Re: Variable idling 1275 tuned Marina engine
Good idea! I have not tried that and will do that tomorrow. But the brakes are working perfectly also, shouldn’t they be affected also? Anyway I’ll try it.

Re: Variable idling 1275 tuned Marina engine
Thanks for the input and questions. The issue was from the beginning after I had rebuilt the engine from bits and pieces. All parts exept block, crank and conrods are new. So Pistons, head camshaft, valves a.s.o. are new. The carbs came out of a Healey BN100 and have been overhauled completely. Thei...

Re: Variable idling 1275 tuned Marina engine
Thanks Bill, Yes throttle cable and choke cable are loose enough and I have checked for air leaks with some brake cleaner but there are none. That was the first thing I checked because of the thermal connection. You‘re right, I should be able to slow it down to stall point but this is only possible ...

Variable idling 1275 tuned Marina engine
Hi, My 1275cc tuned Marina engine drives me crazy. It has got twin HS4 carbs and an electronic distributor with vacuum advance. When started up from cold idle is at 1100 to 1200 revs, idle adjusting screw fully turned out. As the engine warms up idle is rising steadily and after a run on the motorwa...

Re: Stronger Halfshafts
That sounds well and strong. I’m doing the same way but with 22x16mm CFK tubes. I‘ll glue tapped m12 terminals in that will take the rose joints (male) with a locking nut to adjust them in length. I‘m not tempting to do jump starts or races but just a good road going car I can trust in even if it ha...

Re: Stronger Halfshafts
That looks strong! I‘ll make mine the same way. As I don’t like mod in a classic car that aren’t reversible I‘ll make the front bracket screwed on by the bolt that holds the spring. With a tight fit it should be strong enough also.
And I‘ll make my bars from CFK tubes and 12mm rose joints.

Re: Stronger Halfshafts
Hi Phil, Thanks for your reply. I have Spax adjustables front and rear. Can you give me the length of your bars please, I‘d like to do some maths. The strength of a 16x12 CFK tube is about 3 times more than of a 20x3mm steel tube and a glued connection with the rose joints (JB weld) stands some 273k...

Re: Stronger Halfshafts
Thanks Phil, I’ve just asked because of some measures, would have made it easier. I‘ll make some my own and use rose joints as these ar working fine in my Morgan. I understand you have used 1/2“ rose joints at last, right? I thought about 12mm ones which is quite similar. But now I have a few questi...

Re: Stronger Halfshafts
Have you got a drawing of that? The main advantage of these bars is that they guide the axle to an almost strait movement up and down and stop the leaf spring from swinging in acceleration under load thus minimizing tramping of the axle. My Morgan is accelerating like off a sling shot with no trampi...

Re: Stronger Halfshafts
Hi Phil, You’re right! I thought about that also because I made some myself for my Morgan +8 and this was a massive improvement. But the ESM bars seem a bit short to me and I don’t see a good option to fix longer ones. The longer they are the better it is obviously. Anyway, I‘ll think about that. Ch...

Re: Stronger Halfshafts
Fingers crossed. But I like to have stronger ones on the shelf, just in case the old ones fail. I had that once on my previous traveller. Not amusing as it doesn’t have a limited slip diff and has to be towed home.

Re: Stronger Halfshafts
Thanks for that quick reply. I had a look at the site and will order the halfshafts to have them here in case my original shafts fail.

Stronger Halfshafts
Hi all,
Is there any suggestion for stronger halfshafts to use in a tuned 1275/T9 Traveller with a 4,22 diff?
Any hints welcome

Re: Oil Pressure too high?
Well, it is a seriously tuned 1275 Marina engine with raised compression to 10.3:1 and similar treated 1275 Mini engines are usually run with 7bar at 90°C oil temperature. So I‘m more or less satisfied with the oil pressure as it is now. Prior to shortening the pressure relief valve spring the engin...

Re: Oil Pressure too high?
Just for an update.
After having shortened the spring about 4mm the oil pressure gauge shows 7 bar when the oil is cold and some 6 bar at normal temperature. That’s Ok to my opinion.
Thanks for your input and the socket, Phil. That was a great help.

Re: Oil Separator flame trap "Chimney"
Hi, having removed the metal mesh out of the crank case venting canister one may think about installing a seperate flame trap (https://www.ebay.de/itm/264475139257) that is used in Range Rover V8. It then can easily be removed and cleaned separately if necessary. I did so in my Traveller after insta...

Re: Clutch problem, Borg & Beck pressure plate
Thanks Phil, I‘ll keep that in mind for the next time. The item has been sent to the supplier already and the replacement part will be mounted tomorrow. I‘ll see then if it’s better or not.

Re: Clutch problem, Borg & Beck pressure plate
I‘ve tried several times and all possible positions but the pressure plate came out this way always when torqued down to specs. I torqued it carefully and as evenly as possible and a bit of grease changed nothing. It seemed to me that the spring of the deeper positioned part is a bit weeker than the...
