Just a small tip when doing your TBs. If you haven't got cruise control it can be tricky to get the revs right to do do the adjustments. After starting the engine, I opened the throttle a bit and placed a washer 0.5mm thick under the throttle stop thus lifting it just enough to get the revs up. Sorted!! :lol:
The Caterpillar o-ring cruise control method should work too! And since the throttle will still turn with help, you can adjust the throttle if need be!
