Holden HQ distributor problems.

[Coyote]

My brother has just switched over his HQ's 186 with a 202. He removed the 202's distributor without thinking when he switched the motors over. he's pretty sure the timing is way off which is making it backfire really badly. What can he do?

[wbks]

Those 202's are really fun drifting along gravel roads when the steering wheel pops off the colomb and the driver isn't slowing down... Try it some time

[bungbung]

Check the timing, make sure the advance is working. Check the plastic drive gear has all of it's teeth.

[AllanB]

Or buy a FORD

[davereid]

Check the points and timing.

First, roate the engine till the points are on a cam lobe, and are open.
Adjust points gap for 0.6mm.

Then time the engine.

If you don't have a timing light just use a 5w or thereabouts 12v light bulb. Connect the bulb across the coil. Rotate the motor until #1 is on compression stroke, and timing marks on engine are at about 8 deg BTDC.

Rotate the distributor until the points just open, extinguishing the bulb.

Timing is now set.

(Others may know the correct settings, but 0.6mm points gap and 8deg will work OK for most engines.)

The firing order should be on (or near) the manifold..ie 1,5,4,2,6,3. make sure the right lead goes from the plug on the correct cylinder to the correct lead off the dizzy. you probably already tried this tho?

[BMWST?]

souns like you may be 180 deg out....ie firing on the exhasut stroke

put the 186 back in as they are a stronger motor anyway. never had any problems with the 2 that i had, and 1 was in a landrover. gave it death and it never missed a beat.

He said give him a few days to figure all that out.

"How much would it cost to get someone else to do it?" said my brother jokingly, but really meaning it.

not the kingswood!!!!
It'll be towing bikes one day.

He's done that. He knows.

He parked it up, then the steering wheel fell off.

The firing order should be on (or near) the manifold..ie 1,5,4,2,6,3. make sure the right lead goes from the plug on the correct cylinder to the correct lead off the dizzy. you probably already tried this tho?
Yep, already done that. Chur

The 186 was smoking and spitting out oil. It was pretty well thrashed. The 202 is just a cheap replacement until he can afford a 454 big block or bigger.

He had thought of putting a Ford badge up front. Instead I gave him a Honda one. H for Holden.

Do you know about ted bullpit and kingswood country?

Now I do. That was excellent. Churrs :niceone:

[Laava]

Are they still distributing them? Oh.......I see......... as you were!

[Ixion]

The plug leads are switched over. Check the firing order

[Conquiztador]

Might be the retard/adv unit. Check that the vacuum hose is properly connected in both ends, check that it has no holes. And check that inside the distributor it can move the timing.

[Coyote]

He got it working. He has no idea how he did it. He just took the distributor out, put it back in again, and it went. Some would go as far as saying it was a Christmas miracle.

We've also figured out the perfect nickname for it. "Black Dog".

[Ixion]

Bet he turned the dizzy drive lugs 180 degree when he replaced it.

[davereid]

Bet he turned the dizzy drive lugs 180 degree when he replaced it.

Yep, that is a safe bet !

[Coyote]

Bet he turned the dizzy drive lugs 180 degree when he replaced it.
Dizzy drive lugs?

[Edbear]

souns like you may be 180 deg out....ie firing on the exhasut stroke

Yup! You can put the dizzy in the wrong way around in those...

The holden dist has a gear drive...it can go in anywhere.The body can go in anywhere too...apart from the vacuum advance unit hitting the block.He fluked it,that's all.

I remember on my Trade Cert Practical I got a red Holden engine with dist out and disassembled - I got it running with no more than the test light davereid mentions.I got bonus points for the first engine to fire in the class,and more bonus points for it running perfectly first time.And a thumbs up from the examiner when I admitted I didn't know how to use a strobe timing light....and when we hooked it up the timing was spot on.
