Checked the float level today. The float height was 39mm and the drop was 50mm. I had the brass floats and they were in good shape. The both floats were semetrical in height with each other. I then removed the air correction jets and emulsion tubes. Removing the emulsion tubes wasn't easy. They were stuck in there pretty well. I ended up following the instruction on the HP Book to make about 3 threads in tube with 3mm tap and pull the tube free. Both jests and emlusion tubes were not clogged. I cleaned them with carb cleaner and compressed air and put them back. The primary jet was 165 and the emulsion tube F-50, and the secondary 160 and F-6.
I thought about checking and cleaning the main jets but chickened out when I realized that I hadn't done much research about the procedure. Decided to do it on another day, put everything back the way it had been, started the engine and it ran smoothly.
You can use a turkey baster to remove the fuel but its not necessary. The angle of the face of the jets is just right for using a regular screwdriver. Use the screwdriver whose blade fits best in the slot, so as to not ding up the slot with slippage.
At the front of the carb just below the inlet is a 5/8 or 11/16 nut, remove it and above it is a small filter. Remove it and clean it. It can become clogged with fuel cell foam and small debris. Next if your fuel pump has a screw on top, remove it to make sure the filter in the fuel pump is not clogged. It too can become clogged with fuel cell foam and debris. If you find either to be full of foam time to replace your fuel cell foam and flush the system fowards and backwards.
A little off topic, but when I removed the air filter (K&N cone) and its base, I noticed that each bolt and nut was sealed by shiny black rubbery looking stuff. I believe the stuff was meant to keep the nut/bolt from getting loose. The stuff was soft to touch and I scraped all off because I didn't want it to be sucked into the carb.
What is the stuff? Do I need to apply it to the air filter base bolts and the nuts to hold the filter in its place?
If that's the case I'd keensert them. On my VD there's a fiberglass tray that's thru-bolted to those holes, and then I put nutplates in the tray, so the upper half of the duct goes on and off easy. I rarely need to take the tray off.
at this point, it is incompetence in the sport, play tennis!!!!!
