1.) he saws from time to time at 1600 - 1900u/min. if you want to keep the gas (empty run) or when you are driving in exactly this speed range
2.) the gas then only takes on jerky and lets it also jerky off...so these "soft" rules are missing.
3.) I think that it will no longer switch correctly (not always) - but is in a kind of "emergency run"...mostly 3. Gear then (manually switch without function,R / P / N works)
4.) Engine off - restart - or sometimes by itself - drives again 1a and switches butter soft...until the next sporadic time!
The previous owner said I had to have the throttle flap pot set...I guess as a layman I'm going to switch on missing gear oil because of,but the bucking ??? So,you...please help me or I have to sell the nice steamer again
