distributor cap on oliver 1650

willy disher · Oct 18, 2013

when my 1650 gas sits for a while, it misses and backfires when started, i have to take a small torch and heat the distributor cap, then replace it and it quits missing. apparently moisture gets in and causes the problem. i have converted it to an electric ignition. any suggestions?

Sounds like it's cracked. The one on my 1600 was doing the same thing.

You have a very simple problem and is going to get worse unless you replace the cap since that is a sure sign of a cracked cap. You can not see those crack by the way but I bet it you grab that cap when it is running it will let you know there are cracks there since you will jump 10 feet if I am right. So replace it and be done with it

what rrlund said..

look real close for cracks If found .. for an easy cheap fix till ya get one use fingernail polish to seal it... used to do that years ago.

Run it after dark, the spark leak will show up very easy.

Agree with the others that your cap likely has a crack. Crack could be from age, manufacturing defect, or from a worn distributer.

When you replace the cap and rotor button, I would also check the distributer main shaft for excess play in up and down directions as well as sideways slop just to insure that a worn sloppy distributer is not causing the crack.

A very good chance the cap is cracked.Also a good chance you'd see a mini electrical storm if you looked at it at night with the engine running.
If moisture enters the cap you can get around the problem with a shot of WD40 inside the cap until you replace the cap and rotor.
