Curious, why aren't you running a vacuum advance?

Maintenance and Modifications / Jet height HIF 44

Last post by bikewiz - Today at 08:28:22 PM

So I've yet to install my wide band O2 sensor and gauge ( a bit of being lazy, not wanting to lay under the car, and not wanting to destroy the Jethot coating) so I've been trying a bunch of different needles in my carb. I have a write up from Keith Calver on the initial jet height to get the car to start and run of .060 to .075. My car starts and runs pretty well but doing plug chops to check the fueling it's running a bit rich. My question is; short of raising the jet height until it won't start/run has anyone measured the jet height from the bridge for the minimum height, I'm at .060 now. 

Some specs: A+ 1293, unknown cam, definitely not stock, good compression across all cylinders, valves adjusted, new HIF 44 carb with a BCE needle, new 65D dizzy, new plugs gapped to .032, new wires, the correct .9ohm coil according to AC Dodd , static timing set to 10 degress (no vacuum advance) idle set to 1000 rpm, advance of 35 degrees @ 4000 rpm. Also running 94 octane non-ethanol unleaded.

I have some r12 on the shelf in the shop for the rx7. One day I'll get around to recharging it lol

Yes, but there is a temporary respite via converting to 134A, however your A/C system will work about 25% less efficiently, and it will take a while to get the car cooled off.

Not the same thing, but R12 refrigerant  used in the a/c systems of 30+ year old cars is just a little bit pricey these days.

Speaking of F1. I managed to end up in Miami this weekend and was invited out to some special F1 event with a group of people.  Anyway, I met a guy who represents Nascar drivers here doing something for f1 and we got talking cars, so long story short I have access to Nascar races now hanging with the drivers and garages. 

Well if you can share the joy, I would love that for the NASCAR race at Circuit of the Americas.

Ha!  Yeah I need to look up the schedule. I've been dealing with a ton of stuff at home, being pulled 20 different directions. Part of the reason for me going to Miami was to undwind!  I need to go back to my day job for downtime lol.

I was so happy for Lando, even if I did get a spoiler as they were showing the race in the bar at the furniture store. He has missed out a number of times and really deserved for the luck to come with him. I remember the race in Russia where he could have won but it rained!

Well, Red Bull did not get their sums right this time! Although Max might have been able to hold them off, but the safety car changed all that and Lando was in the exact right place at the right time to take advantage of it, then simply drove away from the pack to win his first one for Big Mac!

It was interesting to see that Max could not gain on him at all - in fact by the end of the race he was 7 seconds behind Lando - and neither of the Ferraris seemed able to get there either - they both closed up within 2 seconds of Max but that was it.

Back in the pack they were going at it hammer and tongs, and Sainz and Piastri had a coming together which broke Piastri's wing - the net result was he finished in 13th instead of 3rd or 4th and Sainz got a 5 sec penalty that dropped him from 4th to 5th, moving Perez up a notch.

So, the win definitely brought McLaren and Lando up in the points - it's no longer a runaway but there is significant separation between the top teams. Long way to go in this season still tho.....

One other small detail - Red Bull have already replaced Newey - giving a long term contract to Pierre Wache' till 2028 - so he'll be the one to design the new cars for when the regs change in 2026. Newey now has a clear field to choose from, the big money is still on him going to Ferrari, but it's not a sure thing just yet.

Well, that was an interesting Sprint race - yes Max won again, and Charles was pretty close at the end, only about 3 seconds back but as usual the real fun was happening further back - where Sainz could not get around DannyRickyBobby no matter how hard he tried and Kmag was refining his technique of keeping others behind while the Hulk built up a gap and stayed in the points. Lap after lap he would force the Hamster off line or even off the track - accumulating penalties along the way. Folks said it was "dirty racing", but......it sure was fun to watch. Hamilton to his credit said it was fun racing that hard.
Also - as usual - Stroll was out at the first corner of the first lap. I realize it's his daddy's team, but they aren't going to win any championships with only one driver scoring - who isn't Verstappen.

Big race is this afternoon - it's kinda frustrating to have to wait to watch the race, when they're in Europe it's already recorded when I get up in the am.
