WEBER carbs are out of order (The original blog was written on 15th Aug. 2007)

I connected the fuel hoses to the WEBER carburetors and turned on the ignition.  The fuel pump started to make the operation sound.  But it didn’t stop.  I thought it was strange and checked the engine room, then, I found that the gasoline was overflowing from the WEBER carbs!!!  (There is no photo because I was in a panic…I’m sorry.)

I guessed that the floats of the WEBER carbs were sticking.  I removed the top cover of the WEBER and took out the floats to clean.  Yes, the floats were sticking as I guessed.  I cleaned them and adjusted the float level, then, the overflowing was stopped.


However, the engine didn't start despite adjusting the float level.  The first firing came, but it didn’t continue.  After I checked several points I found:
  • the fire on the sparkplug was okay
  • the engine started if gasoline was sprayed from the inlet port of the WEBER
  • the engine started if choke was operated and idle at 500rpm,
    then the engine stopped if the throttle was opened or choke was returned
  • the accelerator pump of the WEBER for #3 and #4 cylinder was sticking



As everyone thought, the WEBER which slept for 10 years needed to be overhauled!!!

Tip to repair rubber parts

I disassembled the rear axle before.  There had been no progress on it because I started the repair of the fuel tank during my summer holiday. While painting the fuel tank , I repaired the torn rubber boot of the parking brake wire. I guessed it didn ’ t cost high because it was small rubber part.  But I wanted to try the repair method I read on the magazine article before. This was the condition before the repair.  The rubber was torn apart and separated almost. I used this self-adhesive type butyl tape.  I pasted lots of small pieces of the butyl tape on the back side of the rubber boot.  As time goes by , these tapes would melt and stick together.  After this I applied plenty of adhesive “ Super X Black ” on the rubber boot.  On the magazine of MOTO MAINTENANCE , I read the article that the motorcycle seat was repaired with this method.  So , I wanted to try it. After drying 1 day , it became like this....

Fuel tank repair: Day 1 --- new mission started!  

I ’ ve started the new mission that the repair of rust fuel tank. The replacement of the rear bearing at the rear axle was still on the way , however , during summer holiday I could secure a longer time , and the hot climate would be good for the chemical reaction of the rust remover and drying the inside of the tank.  Therefore , I wanted to repair the fuel tank in summer holiday. The target of the 1st day was to remove the fuel tank from a car and to put the cleaner “ MARINE CLEAN ” into the tank. At first , as a preparation for the tank removal , I removed the equipment in the trunk room , such as the electric fuel pump , battery , which may interfere with the work. Next I removed the fuel sending unit and extracted the gasoline inside the tank with hand pump.  Considerable amount of rusty objects came out together with the gasoline. After extracting the gasoline I started to remove the fuel tank. Firstly I removed the screws at t...

Brake master cylinder overhaul #4

I disassembled the brake master cylinder again I repaired on the other day because the behavior of the piston seemed to be not smooth enough.  When I removed the piston at the last time , I checked the condition of the rubber and it looked good.  Therefore , I reassembled it without replacing the rubber. However , again I disassembled the brake master cylinder ’ s piston and checked its condition carefully in order to reassure myself. I disassembled and cleaned the piston and the spring. The condition of the original rubber was not bad , but I replaced it once with the rubber part of the repair kit. Again , however , I felt that the quality of the rubber parts of the repair kit ( left one ) seemed to be poor…. I also assembled the piston into the cylinder as a trial , however , the tight contacting feeling was not enough. As my conclusion , I judged the condition of the original rubber parts were good enough and decided ...
