Yeah, at 75, I can't take too much stress. What you're saying Wagon Master is that even though this engine is tight, my starter shouldn't have any problem spinning that thing around enough for it to fire off presuming fuel flow, ignition timing, along with all that other double-checking. If you've "Been aircooled since 1973," you're not that much younger than I.

Thanks for the quick reply. That procedure sounds cut and dry. Regarding spinning the oil pump; I followed the procedure. In fact, I'd forgotten to tighten the valve-cover bolts and oil leaked out from them. I also saw oil seeping out from the main bearings. Thanks, again. Frog

I'm nearly at the point of staring my "new" engine. New meaning new pistons, cylinders, camshaft, lifters, carburetors, and fuel pump. The carbs and fuel pump are rebuilt. Do I need to "prime" the carbs or will they fill up after a few revolutions of attempting to start the engine? I've spun the oil pump with break-in oil. Engine will be tight. I keep thinking the starter won't turn it fas

Ted, what you said about the centering hole and the end of the shaft makes sense. I measured them and the result is that the shaft of the new pump is .087" longer. Is that difference any concern? Thank you. Frog

OK, Joel and Jim Brandberg, I don't understand the term: " . . . measurement from the center of the locating hole to the bottom of the pushrod is the critical dimension." Please enlighten me. Thank you. Frog

May be I can put this to rest. Using a Husky digital thingy, I measured the protrusion distance of the pump stem for each of the pumps pictured. Clark’s specified protrusion distance for the ’62 to ’69 is 1/8 to 7/32 of an inch. Here’s what I came up with: My measurement on the old pump is 9/64, which is .016” above minimum distance (within specs; no problem). My measurement on

Thanks for the replies. MattNall, I think you're saying to disassemble the new fuel pump and cut the shaft down to the length of the older one????? Regarding "joelsplace," this fuel pump is correct because it came with the car when I bought it half a century ago, and it was functioning as designed just before I decided to rebuild the engine.

That makes sense to me. I'm wondering if I received a pump for a different year. I'd forgotten to ask another question while I was on this subject: I'm getting ready to install a new distributor. Do I need to lube up the gears on the shaft. Thank you. Frog

I've read "Mechanical Fuel Pump Observations..." by kenzen, Jim Brandberg, Wagon Master, et al., and I've decided to reinstall my original fuel pump given all the bad press new ones received. If my old pump fails, I have the option of installing the new one I got from Clark's. I have a concern and wouldn't know how to approach it if I need to install the new one. The pump rod in the new one is

I'm revisiting some questions I had a few months ago regarding tightening the bolt on my new haronic balancer. Here are the comments I made back then: How many repetitions of torquing up to specifications is normal? What happens is that I torque the nut to the specification from the shop manual:40-50 lb.ft. I've developed the habit of occasionally connecting my beam-type torque wrench

Following up on this thread: I've been accused of "overthinking" some issues I've had regarding this and that about my car. I bought a new harmonic balancer (on the advice of forum members) from Clark's at last month's Springfest in Helen. Also bought a longer bolt and used it to begin installing the HB. Everything's working out, or so it seems. My question: How many repetitions of torq

I have this uncanny misunderstanding of the “strength of metals.” I’m amazed when I read that only three or four bolts are used to suspend a Rolls-Royce Trent 900 turbofan engine from the wing pylon of an Airbus A380—the Trent 900 weighs nearly 13,800 pounds, by the way. Also, and this is interesting, the shear strength of these bolts is obviously very strong; however, the bolts are des

I get it, now. Thanks for clearing that up for me. Good point, Tim; however, the cast pulley was stock on my low-powered 95-hp engine so I'm presuming that I can still use it considering I've done nothing to my engine to boost the horsepower or compression ratio--I think. I have read, though, that the sage advice from other members of the forum is to go ahead and get a new harmonic balancer

Thanks for the tip, Matt. Looking through the assorted J-B Weld products, this one seems to me to be the right choice. It's good up to 550 degrees after curing. Do you agree? Thank you. Frog Timothy, I'm not sure what you're driving at.

I put a wire brush to my crank pulley (1964 95-hp engine), today. There is pitting in the belt grove. Saw the price of a harmonic balancer--whoa! Will pitting have an adverse affect on the fan belt? Shorten life, shred it to pieces (read, shorten life), etc. The fan pulley has some pitting, too. I might be able to buy a new fan pulley. Thank you. Frog

This might be another everbody-understands-it-but-me question: On page 6A-52 of the 1961 shop manual, paragraph 37 describes the procedure for installing the crankshaft pulley. It says: "Draw crankshaft pulley into place on crankshaft, by turning retaining bolt until crankshaft pulley bottoms in place." O.K. It get that; it's obvious to me. Here's the phrase I don't get: "Back crankshaft

O.K. Good. I'll make sure each pushrod is "springy" into the lifter, and very little lube. But, I'll lube up the rocker balls with assembly lube as per Bob Helt. Thank you for your inputs. Frog

I'm getting ready to install the pushrods. In Dave's Motohead's video, starting at about 18:46 into it, he goes on to note that there's a little "bump" to pass through to properly seat the pushrod into the lifter. In both Bob Helt's The Classic Corvair and the shop manual for the 1961 Corvair, there's no mention of this little step. Tried as I may, I can't do this. When I push on the pushrod,

After cleaning 11 rocker arms, nuts, and balls, the very last one looked like this. I'm guessing that's not a good thing. I'm thinking of ordering from Clark's the MATED ROCKER ARM SET(12)-W/GROOVED BALLS BALLS & ROCKERS GROUND TO AN EXACT MATCH. Is it worth the extra money for the "ground to an exact match" set for $146.00, over the ROCKER ARM, GROOVED BALL & NUT SET for $117.00? Thank

I've been all over the forum and have seen different viewpoints on how to prepare various gaskets for installation. Some say soak in oil overnight; others say "Gaskecinch" them; and others say just install them right out of the box. Is there sage advice on what gaskets should receive what treatment before installation? Thank you. Frog

In my small town of Clayton, Georgia, we have a Walmart, Home Depot, NAPA, O'Reilly's, and Advance. None had any break-in oil, so I ordered five quarts online, today. Question: In the meantime, while awaiting delivery, can I go ahead and follow the recommended procedure of squirting oil into the side of the valve lifters using plain ole everyday 30W motor oil instead of break-in oil? And do I
