After being let down by Atspeed racing regarding the tuning of my Green Cortina, I spoke to Webcon about the jet sizes in the carburettor. The guy I spoke to had a wealth of knowledge regarding Weber carburettors and after telling him about the issues I was having, he recommended changing my 135 primary jet to a 140 and my secondary jet from a 140 to a 145.
So, I ordered a 145 jet and this morning set about changing the two main jets. It didn't take long and once done I took the car for a couple of drives around the block. It immediately felt a lot better and a lot faster. Once the engine had cooled down, I removed the spark plugs and they looked the correct colour as well. I do need to take it on a longer test drive, but the initial results are good.
The price of the jet was £2.76 plus postage and vat, so came out just over £9. That's a lot, lot cheaper that what the idiot at Atspeed would have charged me if he could have been bothered to tune it!
Once I was happy with the Green Cortina, I decided to replace the leaking half shaft bearing on my Zetec Cortina. This was made more complicated by the fact that I have converted this car to rear disc brakes. So, instead of just removing the drum, I had to remove the brake discs, the brake pads, calliper, the half shaft securing plate and of course the half shaft.
A quick test drive revealed that the grinding noise had gone and it looked like the 3mm wheel spacers cured the problem.
I was really pleased with my days work, It's always good when things go according to plan. 😊
I am from Atspeed Racing and wondered if you could explain to me how my company has let you down and why you consider me to be an idiot as to the best of my knowledge, I have never seen your car and we have never met. Perhaps if you have an issue with either myself or my company you would have the manners to speak to me. What you write in the internet could destroy a company and could lead to a strong libel case brought against you. Please call me to discuss your problem.
ReplyDeleteWe have searched our diary and think you are the customer who dropped a Cortina here to diagnose a poor running issue and rolling road tune. We reported that you had a massive air leak on the induction side of the carburettor we believed was caused by a faulty breather system. We advised you of our finding and you was adamant that that was not the problem with the poor running. As I felt I couldn’t help you I instructed you to collect your car as I was not prepared to attempt a calibration with a major air leak as it could have resulted in a damaged engine. I spent over hour off my time discussing with you and locating the issue, for that I never made an invoice, but let you on your way. I offered good sound advice but we had a difference of opinion. I think you have been very unfair!
