The service manual says #3 position...is that full lean or full rich?
From the AMAL website FAQs:It came stock with the needle in the middle and it ran poorly at about 2500. The book said to put it in the 3rd position which could be interpreted either way.
All new stuff. Seems crazy that they say #3 position instead of full rich or full lean. Thanks for the info

The carburettor works by different throttle positionsIt came stock with the needle in the middle and it ran poorly at about 2500. The book said to put it in the 3rd position which could be interpreted either way.
the timing is right on. It starts in one or two kicks and easily using the compression release. I have a Goldstar and if everything is right including a fully charged battery it fires off immediately. The dire warnings about kickback just doesn't happen.I have had two of these. Timing is very critical! Just my two cents Have fun kicking it!
Probably, but it's best to state the throttle opening. At about 1/4-3/4 throttle, the needle and needle jet are primary.raising the RPM means different throttle positions. I am guessing that by 2500 RPM the needle position is starting to take effect.
You need to mark the throttle drum to see what throttle position you are atraising the RPM means different throttle positions. I am guessing that by 2500 RPM the needle position is starting to take effect.

That depends on engine load.raising the RPM means different throttle positions. I am guessing that by 2500 RPM the needle position is starting to take effect.
Worn needle jets should be renewed.Full rich. Top position of the clip is #1 and is leanest. Wouldn't hurt to experiment, especially if your needle jet has a few miles on it. #2 might act more like #3 if it's worn.
Yes of course, but it's sometimes hard to know when that is. Plug gauges are not adequate since the jet wears oval. A gravity flow test might be the only reliable way, but just a percent can be significant, so it might be hard to get enough resolution.Worn needle jets should be renewed.
