So is it possible to thread a semi rigid pipe through with the body and prop shaft in place, I thought of trying copper heating pipe.

Tim, did you fit it with the body and prop shaft in place?

On another car I had a similar problem , in desperation I ran a wire from the battery to a good quality push button hidden under the dash.and then to the solenoid. when the car was hot and starter wouldn’t turn over but solenoid clicked, I press the button and starter turns over. I think the problem is that the solenoid pulls a lot of current and all the dodgy connections in the circuit coupled with the low battery voltage when the engine is not running give an accumulated volt drop so the solenoid will not pull in. Remember, the starter motor is wired directly to the battery so will

Are you sure the ignition timing is not 180 degrees out, Check by making sure the two cam wheel marks line up and then check mark on crank pulley. Yes I know this is fundamental but the timing light will work at 180 degrees out and you will get farting and banking but no running. All this is from bitter experience! Peter

I usually take off the air box and have a look and feel the inside of the trumpet with my finger. If the pump is on you can usually see the fuel working it's way down the trumpet. all this is from bittter experience, my engine just wouldn't slow down so I fiddled with the lever stop screw then it wouldnt tick over. After trying all sorts of things I bought the better needles and had an instant cure.

When you check for leaks, have a look at the 'O' ring seals between the carbs and the adapter plate and the plate and manifold. If there is a leak here you can get your symptoms. The other think to check is to be certain that the carbs are not flooding, turn on ign and look into the trumpets if there is flooding they will be wet with fuel.

The manual says 12 degrees for Dellorto carbs on contact breaker in a 25d4 distributor but 1975 and onward engines call for 16 degrees BTDC rising to 34 at 4000 rpm, 1976 spec is no vacuum static 7 degrees still 7 at 1000 rpm. however the book also says that you set 25 degrees BTDC at 3000 to 4000 rpm which will give an idle of 7-11 degrees because of distributor tolerances, I assume this is with Lumenition. The chart on p 15 of the manual says 24-26 at 3000 with electronic ignition so perhaps I go for that.

What ignition timing are you guys running at? I have a 2.2 litre 900 engine running on a Powerspark non vacuum distributor with their solid state unit and a new coil. I have set up cam timing dead right and belt tension correct, I am running at 20 degrees advance at 1000 RPM. I would like to see what others are doing. Peter

Mike at LB will also sort you out with a later version belt tensioner upgraded pulleys and cam belt, part ex water pump,and all the goodies to give you better performance like increasing capacity. peter

I would check the pressure at the carb end of the pipe work as that deals with the slight height difference from the pump to the carb. I bought a somple low pressure gauge off eBay and made a temporary connection at the carb input and went from there. I would add that the correct SU pump will deliver the correct pressure so I would check the needle valve in the float chamber. The standard needle is all brass but there is a version with a plastic type seal ring round it, I had flooding trouble and despite all new parts and the correct pressure, I still had leaks, changing the needle fixi

Once again I have had to sort out a leaking exhaust cam cover and I have come up with a couple of ideas to help. To make things easier I took the wheels off and with the car on axle stands put a trolley jack under the sump and took off the engine mounts and so could move the engine slightly toward the off side so I could get at the cover easier. I made up some lengths of m6 allthread slightly longer than the cover bolts, by screwing them into the holes in the cam carriers, the gasket can be coated in sealant and slid down the allthread into position, the allthread an be unscrewed and

I think you need to begin with fuel flow, take the connection off the carbs and check volume of fuel pumped against time by using a stop watch and measuring jug. Also check the carbs for muck in the float chambers. if the flow from the pump is poor, check the filters, some are built into the pump, some in the fuel line. The breather problem can be checked by running the car without the fillercap on. if all this is ok, then suspect the coil. Peter

I wonder if anyone has added sound deadening to interior of their cars, while like the Lotus music, I would like to reduce it a bit. Perhaps I can put something under the carpet in the footwell, Any advice would be welcome.

When you get all the bits, you will find the Powerspark system with their distributor is pretty good, I have it on my Eclat and on my Ronart (Jag 4.2 XJ6 engine) and have done big mileage with no problems, also the complete kit is not expensive.

When I built my engine, Lotusbits told me to leave the splash guard out. peter
