Mine got holes in it years ago. I drove it in very bad weather all the time though so I wasn't surprised. So much salty spray.

Heavy smoking is reduced to cold start, for the rest not much anymore.

Yesterday i had repaired some rusty spots. First Dremel with steel brush, than rust-remover/primer, and a bit of paint an hour later. It will hold up a while.

Think I need to get myself a Dremel and make a start on a few areas that require some work. Other areas may require something more 'heavy duty' than a Dremel

This morning the car did start but it didn't want to rev up. Normally it is a bit sluggish for the first km or so. But today i couldn't get it over 25KmH. So i turned back to home and barely made it back up the hill. I suspected the main jet. So coming home i took the carb apart and cleaned the jets. I had to turn the idle speed up a bit. Then i gave the sprak plug and coil contacts a clean and it seems to run ok again. So let's wait wat it does tomorrow morning.

Did run ok again, only it had sometimes the idle dropping down just till cut out. So i cleaned the idle jet again. See how it turns out tomorrow.

I drilled out the idle jet (0,45mm) it was rather blocked. The car is running fine again.

New problem, same cause i think. I was at a traffic light and the car didn't want to rev up. With a lot of bangs and puffs i just managed to get the centrifugal clutch to engage. The car won't go faster than a slow walking speed. I managed the last 400 meter to work. Later i took the carb out and my boss did drive me home. Will put the carb in the ultra-sound cleaner this evening. I think it wasn't ever restored or properly cleaned.

What fluid do you use in the ultasound ?

A mix of hot water and St.Marc. Works rather well. The water was completly black afterwards. Put it back tomorrow to test.
