I know ya'll get tired of my questions.....is there a book that actually has all the carb info contained in this forum?
Q.1A I have two 1920's, one is a '72, and I'm not sure on the other, but it's pretty close. The metering block on the '72 has a passage plugged with lead. If you take the block off, and look at the back, it has two "J's" turned counter-clockwise & over. The smaller one goes left from the acc. pump chamber, to a hole that feeds the slanted passage in front of the metering block. The little hole that feeds the front passage has lead covering it. Is this factory?
Q.1B The other metering block does not have this, it also doesn't have the little ball inside the "well", connected to the slanted passage.
I hope all this makes sense....Anyone know what's going on? Should I put lead over the other one if I run it?
Q.2A My other 1920 has a plate opposite the fuel inlet, which houses what looks like a bimetallic valve.(Like the one in an air-cleaner) What is it's purpose?
Thanks for any help!
