U20 Spark plugs
I need to buy some new spark plugs and I'm not sure what kind I should buy if I changed out the old distributor to the EI dizzy

Those are what I run. Some run the -11 version with the more extended nose but in my higher compression engine they seemed to cause more ping.

Re: U20 Spark plugs
Not a problem. Carb parts are not very heavy. His plugs actually looked good. He was having an occasional stumble on a hard turn. We were checking the float levels and other carb things. One float was a little bit low. Since it only happened every once and a while it might take some time to figure out if it fixed the problem or not.

Re: U20 Spark plugs
Is there any difference between
NGK BPR6ES & NGK BR6ES spark plugs?
I have 8 new BR6ES in NOS but everything on the forum shows the BPR6ES as the preferred plug.

Re: U20 Spark plugs
The "P" stands for projected insulator and center electrode. Some people claim that the P-version gets the spark closer to the center of the cylinder, resulting in better ignition. You can use either. The NGK website actually specifies the BR6ES for the 1600 engine, and the BPR6ES for the U20. Either one will work.PandaBoy wrote:Is there any difference between

Re: U20 Spark plugs
I prefer the BR6ES as they are less likely to make my higher compression engine ping.

Re: U20 Spark plugs
I should get some of those. looks like I've got something pretty different. Not sure what's different with the BP6EY but doesn't seem like the preferred choice.Gregs672000 wrote:I prefer the BR6ES as they are less likely to make my higher compression engine ping.

Re: U20 Spark plugs
Yes, sorry for the misinformation. It is the P in the BPR6ES that is the problem for my engine... projecting the nose actually seems to change ignition timing slightly. It makes my engine ping.
