Valve adjustment question

Which feeler gauge should be used for valve adjustment on a 76 B? Dumb Haynes manuel doesn't say.
Rick
 
Valve gap is 0.015 in (0.38 mm) cold for both intake and exhaust valves.
Dave
 
See page 24 in Haynes: Hot .013, cold .015, both valves. Or you can get it from the Moss catalog, page 3 in parts list section:
.013 warm, both valves.

Personally I like .013 for my 78 which is the same as the 76. Some people prefer a bit of noise so they know their engine is running.

Guinn
 
I, like Guinn, like my valve lash set at .013 cold. I've never had a problem with that setting and the valve train is a little quieter. It might sound a little ridicules, but I check my valves twice. After the initial setting, I run the engine for about a minute and then go over them again. PJ
 
Hardly ridiculous, Paul! Call it 'prudent' or 'professional'! /bcforum/images/%%GRAEMLIN_URL%%/grin.gif

...and a "snug" 0.014" is good for an 18V street engine (warm) around here. I'll use a "Go, no-go" on pass #2: 0.014" fits, 0.015" doesn't. But that's just me.
 
I do the same, Doc. Check twice except I use .013:go, then .014:nogo. Except for that darn #2 valve on my particular engine which I set by ear as the rocker is grooved.

Where does the go-no go feeler gauge come from?? I got one at napa but it is difficult to use. The blades are 1/2' wide-but have two measurements per. One edge of the blade is one measurement while the other edge is a different measurement.

Setting the rockers by ear. Remember way back in the dark ages when the old chevy cast iron sixes were around? The MG engines remind me of those old chevys. We used to set the rockers with the engine running, by feel. You could actually feel the difference in the rockers by holding the tip of the rocker between your thumb and finger and if they didn't make noise, they were set to tight. Ahh, the so called good old days. PJ

Two different wires are employed here. One fits, other doesn't.
 
Actually, the Morris B series engine is a pretty direct copy of the Chevy stovebolt 6, except for 2 missing cylinders, so your analogy is a good one!
