Engine Diagnosis

Yes, timing lights measure both timing and RPM – mine does. And, it has a 2 and 4 cycle setting for the reasons mentioned in the discussions. I knew that the wasted spark design would not affect the timing function. But I expected it to read twice the real rpm when on the 4 cycle setting because of the wasted spark design and the fact that it uses an inductive pick up on a spark plug. Thanks for confirming that for me. The problem is, I dont think it actually is reading twice the rpm – but rather the correct RPM, just based on the way the engine sounds, so I am going to find another way to check it, as one person suggested. I am not sure that a conventional tach that connects to the points will work on this magneto design, however. It is in a gravely clean-cut 70, and its rated at

Risky, since it requires expert timing to make good contact. Agricultural shot — See Cow shot. All out — The batting team is said to be all out when ten of its eleven batsmen are dismissed. The eleventh batsman cannot continue without a partner, and is recorded as ‘not out’ in the scorebook. All-rounder — A player who can both bat and bowl, or occasionally, both bat and keep wicket.

Bowler-wicketkeeper all-rounders are a rare breed.

I really like that idea. This is sickening and, ironically, such an extreme overreach. So yes, I did respond to the peer-reviewed paper. The fact that Gelman is referring to a non-peer-reviewed blog, which uses a new statistical approach that we now know has all kinds of problems, as the basis of his article is the WORST form of scientific overreach. And I am certainly not obligated to respond to a personal blog.

That does not mean I have not closely inspected their analyses.

SOLVED: How do you hook up tachometer to adjust idle speed

At every mile km service interval. Check for proper RPM and ignition timing as follows: HD D into timing inspection hole. Be sure view plug does not touch flywheel. Locate the proper timing marks for your engine.

May 03,  · Now that the shuttle is loose, turn the hand wheel until your needle is all the way in the down position and just about to start on the up swing. Once you have the needle down, rotate the outside of the shuttle until the point of the hook is just above the eye of the needle.

SH B is offline Re: Originally Posted by Trip.. View Post The dist will advance itself. The timing advances any time the engine rpm increases, to a point. That’s the mechanical advance you are seeing. The car doesn’t have to be in gear for the mechanical advance to come in, nuetral and park are the customary ways to check it. You need to realize that when you loosen the distributor hold down clamp and rev the motor, then tighten the clamp, you have changed nothing.

Once the motor returns to idle, all that advance you saw on the balancer goes away because the weights on the mechanical advance have closed back up without centrifugal force of higher RPMs to keep them open against the spring pressure. The advance returns to whatever you have the static timing set at idle. The less vacuum it gets, the less advance you get. So at idle, the most vacuum the motor makes, you have the most vacuum advance – this assumes you’re on manifold vacuum, there is no reason to use ported vacuum.

When you stab the throttle to wide open, the manifold vacuum drops, so most of the vacuum advance drops off too. At cruise speed some of the manifold vacuum comes back so some of the vacuum advance does too.

A Tuning Procedure by Nathan Hall So happens that while Nate was writing this procedure, I had the need to use it on my newly rebuilt As an amateur restorer, I first set out to create the engine stand front end of a badly burned out and a portable starting caddy I call The Start Kart. The cart has two battery bays, storage for the compression tester, timing light, misc fittings, etc.

Most people put all that on the engine stand, but I wanted it portable so I could roll it up to anything to diagnose problems. It was the perfect thing for this project.

Use a Timing Light For this thread I’ll cover using just a basic timing light. No advance dial or buttons. I won’t cover different models of vehicles, just the use of the light itself. Be sure to check your manual for specific applications and the actual adjustment of the timing. This thread is only to show you how to check your timing. Connect the black lead to the negative – side of the battery. Connect the pickup, should be a black squarish style clamp, to the 1 cylinder spark plug wire paying attention to the arrow on the clamp – the arrow will point to the spark plug.

With the engine “off”, look for a timing mark on the timing cover of the engine. It’s located behind the crankshaft pulley. It should be the largest pulley at the lowest point of the front of your engine in the very center. This image is for instructional purposes only. See the tab on the engine?

Timing Light recommendations

How do you set the timing on your Chevy ? IN order to answer this question, the year of the motor is anecessity because the type of ignition differs. Yet, since you aretalking about setting timing it is probably a motor with adistribuitor, as opposed to coil packs. To set timing, you musthave a timing light; a light with an advance is optim…al and what Iuse. Start off by connecting the power leads of the light to yourvehicle’s motor and the other lead wire to the number one cylinderplug wire on your motor the cylinder on the right bank in the veryfront when facing the front end of the vehicle.

Then, start thevehicle and point the timing light towards the left side of theharmonic balancer, there should be a small plate with an “A , 0 ,and R”.

The Opti-Spark ignition system breaks tradition in a number of unique ways beyond its optical triggers. The following technology is represented in this design: The combination of two systems in one.

I have a 12V-powered ignition timing light of the “old” type, where the pickup fits in line with the spark plug. While it still works great in its original environment, deep plug wells and long lead shrouds make it well-nigh impossible to use on contemporary engines. I usually work on the philosophy of buying high-quality tools with the expectation that they will outlast me. In this case, progress sic has outsmarted me, but I would rather modify this unit than outlay for another one.

The current unit has no trigger cicuitry whatsoever, just running the HT line direct to thre trigger electrode. Has anyone any details of how to set up an inductive pickup to trigger the flash tube? Ideas on how to make a suitable snap-on pickup assembly would also be welcome. Wow, i had forgoten what a timing light was. A friend of mine has one and asked how to use on a VT commodore the other day.

No go, it has its own timing light built in to the flywheel or somewhere. No dizzy these days.

Uncovering The Secrets Of Ignition Timing

Check other factors that may masquerade as a timing problem first; there’s no sense in taking your machine apart if you don’t need to! Be sure that your needle is not bent and that it is inserted completely and screwed down tightly. Check that your needle, thread weight, and fabric are compatible. A heavier fabric requires a larger needle and thicker thread.

Apr 25,  · When done if you have an inductive timing light you can hook it up to the appropriate spark plug lead and do a timing check at idle; you can also check your spark advancer at RPM by looking for the ” mark in the timing window.

I’ve had to remove 1 plug on many engines over the years and bring the piston up TDC – I’ve used a stick of plastic or wood and let it rest on the piston and turn the engine by hand to find TDC – can get very close, even closer if you have room to set up a dial indicator. Then you make a reference mark of your own on a balancer or pulley and the block, then use a timing light to get accurate setting – luckily I’ve had a Snap-On light with adjustable advance capabilties for years – this is great to check your mechanical as well as vacuum advances too.

Yes, dwell must be set before adjusting timing too – if you don’t have access to a dwell meter, just be sure you get the closest setting with a feeler gauge that you can. Also the biggest mistake people making when servicing points is not lubing the rubbing block which will wear down very quickly, thus changing dwell which in turn changes the timing. Don’t use axle grease either – NAPA has great point lube with moly that won’t sling off and get on the contacts.

Another point is that manufacturers usually have a coating on the point contacts to keep them from corroding while on the shelf – a swipe or two on a clean matchbook cover or even a clean T-shirt will remove this preservative and save some grief.
