flooding real bad

johnzmu · Post by **johnzmu** » April 23, 2010, 9:27 am

I am going to put plates on the 66 and use it for a bit of a daily driver, but i need to clear up a couple of issues first. I can be driving it no problem and then all of a sudden, it will start to flood. It floods so bad, fuel pukes out the carberator and there is a huge puddle of gas on the intake, scary

. Ive had the top of the carb off several times to look at the float and related items, but I just cant see anything wrong. Any ideas?

Second, can anyone clear up for me the difference between dwell and gap in a set of points?

Third, when you turn off the wipers, they park pointed straight up

. Is there some sort of adjustment for this?

Thanks in advance for any help.

The carb my 65 did that. The needle was hanging up sometimes it would stick away from the seat and flood the engine like you just said and sometimes it would stick closed and not run. When you pull the top off can you work the float up and down and watch to see if the needle works freely or hangs up

Gap is the distance between the the contacts on the points. Dwell is the angle in which they open. Also remember that dwell can change timing. As for the flooding it sounds as if there is a needle and seat problem or if that checks out yyour fuel pump may be putting out to much pressure forcing the needle off the seat.

Flooding
buy a carb kit and replace the needle and seat. also replace the filter, dirt can keep the seat from sealing. If you still cant get it to stop use an electric fuel pump and put a switch on it so you can shut the fuel off. once it starts to run low you can switch it back on and it will flush out whatever was holding it open.

Dwell
the number of degrees of rotation that the points are closed or how much time you give the coil to charge.
Gap
The distance the points open
Having a larger gap reduces the dwell because the points cam lobe is a fixed height and more time is spent with the points open.
too little dwell will cause poor performance at higher rpms because the coil can't saturate / charge properly and won't produce enough voltage. Too much dwell and the coil runs very hot at idle and wastes a lot of energy. It can also miss and flutter if they are not opening cleanly/ crisply.
Most electronic ignition modules automatically control dwell as a function of rpm.

Thanks for the replies. what would be the proper way of setting dwell? probably with a dwell meter right? well Idont have one, and I dont know anyone around here that does.

Nevermind, I answered my question on setting dwell by reading 62galxe's link. Great info! any ideas on the wiper motor? I think i asked this question on here some time ago, but got no replies.
