1974-76 Blueband 200 (20hp) Timing Trouble.

[STUTE]

Hi Guys.

Ive got a major drama on my hands.
Its now fishing season and I haven't got a boat to go anywhere or catch any fish.

My issue is the timing on my 1974 (I belive, maybe 76'). Ive had the motor apart, replaced the Top cover with a custom cover (The old one looked like swiss cheese).
Motor is complete and back together, I have to book for the motor and im so unclear about what it says.
Its tells me I have to start it to do the timing, BUT I CANT START IT IF I DONT KNOW WHERE THE TIMING MARKS ARE.

Im usually very motor savvy with this sort of stuff, ive rebuilt many a motor in my time, but this has me completly stumped.

Can someone please describe to me in detail how to time this old beast to get me out of the house and away from the Missus.
(or at least point me in the right direction)

Its sparking a good blue spark, ive got fuel, its got air, it just wont run. AT ALL, it coughs and pops, but its not sparking at the right time.

My serial number is 8036298 (Im in Australia) I dont know what year it is, ive looked on the sites you guys have provided but with no resolve.

This is my last opportunity before I buy a new one. I cant deal with it anymore.


Thanks

Stuart

Your engine was the 248th engine built in 1976, if it's a manual start the flywheel should have 2 lines cut in the top that are visiable through the timing window in the starter housing. Remove #1 plug and turn the engine till it's on TDC, and mark the line on the flywheel with some white paint, so it can be seen easily with a timing lite then with the engine running at WOT set the spark at 30 to 33 degrees depending on the fuel octane thats available.

Thanks For The Reply. BUT THERES MORE< LOL

Now, where do I line the timing marks up with on the Starter Housing.

It has the markings on the housing on the front.

I know I have to line somthing up with 33 degrees (The flywheel before I start it??)

Also, when the motor is at TDC I have some movment of the fly wheel, before the piston starts moving again, I suppose you would call it slack. Its that a problem?
Now, how do i know where TDC is when I can get a range of movement in the flywheel.

Thanks

There will be some movement at TDC, and the flywheel mark should line up with the TDC timing mark on the starter housing that is clockwise of the start rope pulley, 33 degrees is counterclockwise of it.

ok gotcha.

So i have to line that up.

Whats the point in the timing light then?

How do I adjust the timing once ive lined it up??
Do I take the housing off and move the fly wheel around and retighten, time it again.

If I do that, i take it off TDC and it wont be.

If I line the marks on the fly wheel with the TDC mark, It should start??

My Arm is sore, LOL.

Re: 1974-76 Blueband 200 (20hp) Timing Trouble.

Timing is adjusted with a timing lite and the engine running at WOT but turning the stop screw on the stator plate linkage stop, to stop the advance at 33 degrees. Lets backup some, first the engine can not get out of time far enough to not start. If the timing mark on the flywheel don't line up with TDC on the starter housing and #1 cyl. on TDC, some one has disassembled the flywheel at the flex plate (Hub) and not indexed it right when putting it back on. If thats the case then you will have to remove the starter housing and index the flywheel at #1 at TDC.

Thank-you muchly
I now have my motor started.

FIRST PULL.

I had the coils in the wrong places. Swapped them over and now it runs beautifully.

Thank-ou so much for your help.
Much appriciated.

Well what are you waiting for. Get your pole and get out there and do some fishing. Grin!

LOL, if it were that simple, I would.

Now I have another drama.

The shifter has slipped.

Weird thing it, i didnt really have that part of the ingine apart. I only took the power head off and a couple of bolts on the shifter.

Now If I put it into reverse, im in Neutral. If I put it in Neutral, im in Forward and If I put it in Forward, im still in Forward.

Any Ideas??

Should I start a new thread??

Thanks

You need to remove the lower unit, use pliers and shift the unit into rev gear then put the upper in rev and reinstall the unit.
