Re: Replacing handbrake mounting plate
I'm going to start with the lever, and if that checks out move on to the cable.? If all that is good and I still don't have an e-brake then I'll follow the procedure you specify.? Starting next Spring of course when the temperatures are above freezing and the salt has washed off the road... -- Toaph

Re: Replacing handbrake mounting plate
I agree 100% with the acetone and ATF, the best ever.

Thanks for all the generous feedback. I'm just doing what I enjoy doing... with friends. That's what has been so great & rewarding about the Lotu community.

It's quite easy to use a GM HEI module (like the one inside the Lucas
AB14 ignition amplifier) with points. On Thu, 2 Jan 2025 at 21:19, James coyne via groups.io <tecnosound@...> wrote:

The difference I wrote about earlier is NOT between the Lucas 23 and 25 models... as I stated The Type 23 & Type 25 are BOTH "small bodied" distributors, and neither one can handle either the high current or the high arc-voltage associated with using a high performance/ low resistance ignition coil... like some of the "Flame-Thrower" models. In the early 1970s, the Type 23 & 25 were replaced by the physically "Larger Head" Type 43 & 45 distributors. In both pairs, one was purely mechanical advance, and the other added an vacuum advance/retard capsule onto the outside of the distributor's head. If you have either a 23 or 25, then your distributor is built "TOO SMALL" to handle a hi-performance ignition coil! Period! And there are no Band-Aid fixes you can make to either a 23 or 25 that will make them compatible with a hi-performance ignition coil! The Lucas Type 43 & 45 are very similar to their smaller 23 & 25 predecessors, just made with larger "heads. The shank part that slips into the engine is the same, so upgrading from a 23/25 to a 43/45 is plug-n-play. But the 43/45's larger "head" puts the spark plug wire terminals on a larger diameter centerline circle, and therefore, further apart. Further by enough that the high voltage arc can no longer jump between the plug wire terminals internal to the cap. When dealing with high performance ignition coils and their HIGH voltages, SIZE MATTERS, and you cannot make an older, SMALLEmall 23/25 distributor grow-up. So, I got stuck in the wrong gear, and was comparing the Lucas Type 23 to the 25... wrong. I should have been comparing the early & smaller Lucas Type 23 & 25 to the later & LARGER Lucas Type 43 & 45. And it's the LARGER part that makes the 43/45 distributors compatible with the later high performance ignition coils. The earlier 23/25 distributors are simply too small to be compatible with the later "HOT" ignition coils. That is NOT a MARRIAGE! Regards, Tim Engel 01/01/2025, 5:58PM PST, Tim Engel, TSEngel@... wrote: The Lucas 23 distributor is the older model that preceded the type 25. The major difference is that the Type 23 has a smaller "head" that squeezes the plug wire terminals down into a smaller diameter circle. The net effect is that the plug wire terminals are closer together on the Type 23, and further apart on the Type 25. |

I'm not an automotive machinist. I'm an owner/ wrencher who likes to work on his own cars. But there are points at which I draw the line, and take the big work to a pro. Cylinder head repair and rebuilds are something I take to the pros. I live in a metro area, and I'm fortunate to have a number of very qualified automotive machine shops as options. While I stay out of the way and let them do their thing, I do try to stay mentally involved... I want to know what's going on. One thing I do know for certain is that it is critically important to remove & install the valve guides and seats "correctly", which includes properly/technically heating the head in preparation for disassembly, and both properly heating and chilling parts in preparation for re-assembly. Just "What size punch and hammer do I use?" is NOT the correct mindset!! The Lotus engine's cast aluminum parts are made of a British Industry Standard alloy called "LM25-TF"... The TF being my bad memory recall of the dash-suffix that indicates the post-cooling "Temper" (hardness) spec. For the LM25 used in the Lotus engines, the temper is the most thorough option available for LM25... I have a spec sheet I can dig out if/when you need it... but not now. Currently, I'm not home, and won't be for a while. I have a 907 head at home that was annealed when the engine over-heated. The engine started after I filled the cooling system, but a short time later it started to rattle & clatter. A couple of valve seats (ie, the steel "ring" inserts) dropped out and were trapped between the combustion chamber and the valve head. They were getting hammered pretty badly. I took the head to one of the pro-shops, and he installed new, over-sized OD seats and guides, and used all the proper pre-heating and chilling procedures during assembly. I installed the head, the engine started & ran, and I drove it for a couple of days... then the clatter started again... the valve seats had dropped out again! The machine shop couldn't believe it, but he offered to re-do the rebuild for free. When I picked it up, he told me he had set the valve seats deeper than spec, and then peened-over and smooth-finished the surrounding metal, capturing the seats. "Those valve seats will "NEVER" come out again!!" Two days down the road, the familiar clatter came back. It's been many years, but I still have that head as a reminder of how badly you can screw-up LM25 aluminum alloy BY NOT HEAT-TREATING AND TEMPERING IT CORRECTLY. Don't think for a moment that it's something you're going to accomplish on your first try in your kitchen oven or bar-b-que!! If you have to ask for advice on how to do it properly, then you're not prepared, and I strongly recommend that you take it to a pro who has all the proper heat-treating, chilling, and assembly tools.

Upgraded front brakes from SJ Sportscars
I'm just now installing the upgraded brake kit from AP Racing sold by SJS.? ?It turns out that the anti-rattle clips don't fit in this caliper, as it is specified for racing only.? ?I confirmed this directly with AP Racing.? ?So I'm installing the setup without the clips.? ?Just wondering if anyone else has used this kit, and if the pad noise without anti-rattle clips is annoying, or no big deal? |

Re: What distributor are you running in your 907?
I built my own system on my 1977 Esprit S1. The left side of the engine cover has a 4 inch pipe on the side going to the back of the inside behind license plate . There there is a bilge fan and all the engine heat exhausts around the license plate.? On Thu., Jan. 2, 2025, 7:23 a.m. Bill Galbraith via , <Lotus=[email protected]> wrote:

Re: What distributor are you running in your 907?
¿ªÔÆÌåÓýNo engine bay blower on the S1, only on the S2. For temperate climates, the right-side rear-quarter window ¡°ear¡± has trunking (#1 in parts manual diagram BEB). For high ambient temperature climates, there is a blower motor under the right-side rear-quarter window, where the battery is on the early S1 cars. There is a thermostat (#14) mounted on top of the air box that completes the circuit to ground to activate the fan motor. ? The parts manual doesn¡¯t break out Domestic, Federal, or ROW markets for temperate or high ambient temperature. I don¡¯t know if this was an option when the car was ordered, or if just some cars got it, some didn¡¯t. ? For the S1, I¡¯ve seen various methods to implement an engine bay blower, sometimes cutting into the engine cover. A cleaner method might just provide a blower, such as for an inboard engine boat, mounted below the engine bay flooring, just to move some air around. Heat rises, so anything to move some cooler air up under the engine cover would probably be beneficial. ? Just my $0.87 worth ($0.02 adjusted for inflation) Bill ?
