I try to keep the list of ‘things I don’t want the landlady to know about’ fairly short. I don’t drink in the house very often, I haven’t had any gentlemen callers ( though I should perhaps add that they haven’t exactly been forming a queue) and I haven’t sat on her sofa in my pants to watch Strictly.
I am not sure that this adds up to enough in the ‘virtue’ column to make up for ‘arsing about with petrol on her garden furniture.’ Close to the spot she likes to stand for an after-dinner ciggy. But last Friday was dry, clear and still, while the forecast for the weekend was crap again. And, based on prior experience, I had about two hours before she came home. Fortune favours the brave and all that….
Checking the float on a 2CV carb is simple. Whip the top off, turn it upside down, and check that the dimple in the middle of the float is 18mm plus or minus 1 above the edge of the carb body. If you’re feeling thorough, check both floats and average it out.
Checking the Jikov 2829 CE requires a Nutella jar, a ruler, a length of tubing, a syringe, a permanent marker and some non-latex gloves. I couldn’t find my syringe so I had to nab the landlady’s Highland Spring bottle from the draining board. I hope she isn’t still looking for it.
Eat the Nutella. (I had to skip this step as it isn’t Fat Club compliant and spoon it into a tub instead.) Mark a line 10mm from the lip of the glass. Balance the top half of the carb on the jar. If you left the fuel hose on the tap go and fetch it and attach it to the carb. Using the syringe, feed the carb with petrol until the valve closes. Wipe up the petrol you spilled on the table before it melts it. Realise that over-enthusiastic syringing has resulted in overflow, giving a false reading. Syringe the petrol back out of the Nutella jar and try again. Keep trying until the valve closes just as the petrol hits the line that you drew.
Worry about meniscuses and other visual tricks.
Decide that time is short and you are close enough for jazz.
Assembly is the reverse of disassembly. Though without dropping any screws down holes this time. David Angel at F2 sends brilliant step-by-step instructions, though not for the fainthearted. I don’t think Haynes has ever suggested I should roll a rubber hose back like a condom before fitting it, but it did the job beautifully.
By 5pm on Friday I had a bike that started and ran. Which was a significant victory. Since then I have mostly been trying to set the air mix screw, with limited success. I’ve watched a lot of YouTube videos, mainly by a chap called Mustie1 who is fettling a barn find Jawa at the moment. I need him to stop fannying around polishing the paintwork and show me how to tune the carb!
I also found a brilliant description of the process on the Yezdi and Jawa Club of Chennai website.
“select a place far away from the city or your residential area so that you do not disturb the tired, sick, disgusted, old people or babes (babies) living in your colony. You are likely to be shooed away from them when you are at a critical point. You may choose a place near your girl friend’s house just to impress her! Put the bike in main stand and get hold of your screw driver. That is all you need, together with your eyes, brains and ears.”
Yesterday I thought I had this cracked. I headed to a local beauty spot where one of this year’s RBR landmarks is located. I selected a place far away from my colony and adjusted the screw until the engine had a cheerful sound and the throttle response was quick without hesitation, deviation or repetition.
Today we were idling like a dog again. But yesterday was beautifully sunny and today was grey and damp. Maybe that makes a difference?
Who knows. After all the surgery I feel it’s now time just to start riding and see what happens. What’s the worst that could happen? Well, I could melt my pistons, lock the engine, crash and die. But I’ve done that once before (the melting part, not the crashing and dying part) so hopefully will feel it happening while there’s still time to pull in the clutch.
