Righto:
Grumpy, Your explanation about the throttle cable positioning was spot on after I had a better look. Last night I adjusted the cable accordingly and put the engine back together. I checked my work early this morning against Bigted�s explanation and the throttle lever lined up correctly with the notch on the top carby plate. The lever now moves in a clockwise direction as you indicated.
Joe, My bowl nut/jet is very different to yours. I did however notice sometime very strange with the bowl bolt/ jet when I first unscrewed it from the carby. Inside the jet it had a rubber lining that protruded slightly out of the end of the jet. This was very brittle and when touched it perished. It was only a very minor piece which I thought might be something that sealed the jet against the emulsifier however I could be completely wrong. Perhaps your rubber O Ring was serving a similar principle. I would be interested to know if your bowl bolt/ jet has a similar rubber lining or if any others have an idea that would be great.
Bigted, Thanks for the explanation. As stated above I went and doubled check this morning at the full throttle position lines up exactly with your diagram. So thanks for confirming. I haven�t played with the adjustment screws yet due to my problem below.
My result.
I went to start the engine and it starts for about a second then dies. The speed setting is definitely correct as it sounds much better however, I think the needle and seat might be the issue however I am not sure. I checked the seat and it appeared to be ok however I wasn�t able to get it out without damaging it. I understand there is a special Tecumseh tool and others say a crochet hook does the job. Is there a special trick for setting the needle and the seat to ensure they are positioned and operating correctly? Joe you mentioned checking it so I am curious. The configuration of how the needle and clip attach to the carby float to me seems prone to failure. Would someone have a photo of it set up correctly as I might have it wrong!
I did some more reading about these carby�s last night. They don�t appear to be very popular with many people.
Any suggestions would be appreciated or if you guys need more photos let me know. I hope this turns into a good thread as information on this type of engine is limited!
