Reiver

Had an issue with a bit, not much, of muffler/tail pipe, backfiring that is usually a lean condition. I know I am not lean so suspected something in the ignition system. I changed the plugs from the Denso Plats to NGK BCPR 7's and that seemed to fix the issue. Need the cooler plug with the 10.5-1 compression. Cooler day today but we'll see when it is hotter. Looking at the plugs I think # 1 was not working properly.... the residue was not the same as the others and the compression in that cylinder is excellent. I also lightened up that carb throat (idle) a tad that feeds that cylinder. Fun dialing this booger in. Had her up to 90 mph today, pulls great....90 mph in the 7 is like 150 in the Corvette. Same fun.

I have the electronic ignition with a coil pack mounted where the dizzy was...thanks for the starting point.

Looking for Magnecor or similar upgraded types available in the US by reference number....I've seen the ones available in England.... any crossover numbers?

That dual looks like it'll work

No, it's not...it is made for padding and oblong so the thick portion faces the driver/passenger.... oh, I see Caterham's flip every day here abouts .... but that's not my worry...a small shunt where you are launched into your straps and then rebound.

Lol, I'm in Arizona in a small town about 70 miles from Phoenix.... nothing rusts here...nothing. One of my favorite things actually....

Where did you source that pad Charles?

Thanks gents. Bill I've seen that padding and it is hard itself, that is for use with a helmet I believe. I'm not sure about its ability to absorb shock unless wearing one. Still, better than steel. Charles, how hard is that padding you have?

CBuff, yeah, my padding would fit under that no sweat...I've sent in the new naked bar measurements, so we'll see what shows up (in 8 weeks or so)...we have the same roll bar. Dreamer, Very nice cover there...who made that for you btw. I suspect your interior guy did so. If the hood comes a bit large it'll be perfect. Either way I'll figure a way to pad the bar. Just makes me feel better even if it is not really a thing. The FIA cross hoop I have leans a tad forward but is mostly upright.

More than likely true...... I am only 5'9 and 180 ... my wife tho is 6'2...lol...nah

That is thicker facing forward, oblong, but obviously thicker than required..... I think I'll order the hood with the measurements taken without the padding and make it work when the top arrives. As you mentioned a V wedge in the proper location could offer more room.

Gents, I contacted soft bits yesterday to get a half hood and once they got my measurements Tristan said it would not work due to the padding on my roll bars. They could send a pattern, I'd measure and send back and no idea about the price etc...sounds like a pita. I will need a 'sunscreen' come summer. I rarely see padding on anyone's bars but it seems to me a pretty obvious safety issue if in an accident. Am I being overly cautious and what is/are the experiences here. I do use the 4 point harness.

I've put about 300 miles on my new to me 7...99 build Vaux 2 l. I know I'm not telling you anything new, but this thing is simply brilliant. I've had an Elise, and Maserati's and Porsche's, Jaguars etc., but the driving experience and fun level of engagement in this Chapman platform is simply fantastic. I bought the 7 sight unseen and had never seen one in the flesh so took a chance. I won the lottery here. Just a perfect combination of old school and not. I thought I'd want to change the large chrome headlights but, damn, I love looking thru them and the clamshell front fenders. Sometimes you just get lucky aye?

Looking for a nice spare....as new or repairable ....

What main jet's /idle jets are you running. My car came with 145 mains (middlin emulsion tube) and F8 55's. It was a tad lean on the low end so went to F9/55's and that dealt with the lean muffler popping. I may try 140's as I suspect an over rich on top. What do you run. All individual throats are balanced as are the two carbs. The only mod is an SBD uprated cam (mild still use the original tappets) so about 190+ hp so SBD says.
