I know what WOT means but whats WFO mean?

 

[kibble]

Wide Fully Open? :arf:

 

[Kenny_McCormic]

Wide Friggin Open?

 

[kibble]

Waffles for Orphans?

 

[Russ2251]

It's here:

Mr. McCormic almost had it.

 

[kibble]

Dang, I was sure I had it.

 

[Jerryburger]

Dang! I thought that was a common term... I think I'm showing my age...! Either way, I've got tweaking to do on it still.

 

[Jerryburger]

Brief Update:
Tightened up the driven pulley spring and got it to close further, taking up slack in the belt. Got it to run about 5 minutes with the chain removed, so I could check operation of the clutch and it sputtered to a stop.
Filled it back up with gas, and now all I get are sputters, and occational run s of about 1 second. (Lots of pulling the starter in between. It's geeting gas and spark, plugs are clean, but I'm thinking maybe something happened to the points? Or maybe the flywheel somehow shifted. I'll have to look.

And here I thought I was going to attempt another top-speed run... hah!

 

[crazycart]

Woodruff key could have sheered, check compression also. Carb could have gummed up, plugs could be shot (even if clean)

 

[Jerryburger]

So far- plugs are brand new (2hrs use) compression is normal, and it's getting gas. Maybe it sheered the pin.... not much else to it.....
I always wanted to get a peek at the points, so this will be my chance.

 

[crazycart]

How do the plugs look? Ive had the key sheer, it will still spark, but is advanced/retarded, and it would just pop, so that's a good chance.

Hmmmmm.....
Now I'm a bit frustrated. Pulled the starter, and the closest I can get to the points is through the timing slots on the flywheel. Since I have NO clue as to whether this is right or left-handed thread, I can't REEEEEALY rail on the wrench to get the flywheel nut off. Normally, you can look at the end of the threads and figure it out, but there's none exposed. As best as I can figure, timing is "on", but the more I look at it, the more the spark seems weak. I'm going to try a spray can of contact cleaner on the points to see if that will help. Hopefully I'll have some good new soon, and another stab at a Top-Speed run.....
58mph! (That's just SAD!) ....It's KILLING ME!

 

[crazycart]

It should be normal right hand thread. Your going to need a impact wrench. And to pull the flywheel i used a thick steel plate with 3(maybe 4? depends on how many bolts the flywheel accepts) holes drilled in it.I then put the bolts through the plate and threaded them into where the recoil rope thing bolts onto the flywheel. The middle of the plate should butt up to the end of the crankshaft and when you tighten the bolts slowly it will pop the flywheel off the shaft. Oh, and whatever you do, don't hit the end of the crankshaft with a hammer...learned that the hard way...(smashed threads)

 

[Russ2251]

Tapping flywheel with a plastic mallet (while under tension) helps.

 

[Jerryburger]

THX to both of you guys! You must be psychic, because I finally did get the nut off and no, the flywheel can't be pulled off with a jaws-type puller. One coil is being shorted to ground whether the points are open or not, so there's something up with the primary wire. Gonna HAVE to get that flywheel off.

 

[kibble]

What about tapping it, like Russ said?

 

[crazycart]

These flywheels are pressed on, and wont come off by just tapping. You will have to order a puller for that engine (look on ebay) I had a problem with mine, the main wire going to a coil was rubbing on the crankshaft end and it was grounding it out. Easy fix. I would replace the points and condensers while your at it.

Well, no dice. I got a 1/4" thick piece of steel, drilled the 3 holes and threaded it into the flywheel to where it was putting quite a bit of tension on the flywheel and nadda. Even tapping it under tension didn't budge it. I backed off in fear of snapping one of the 3 bolts. I guess that's what 30-something years does to a press fit joint! I'm going to load the whole kaboodle into the van and take it down the street to a shop and see if they can pop it loose. Otherwise, the closest replacement is the little Polaris motor. (Which hasn't been started yet.)

 

[Russ2251]

I once had an old Mercury outboard engine.
Took 2 weeks to remove flywheel.
Every once in a while I would put more tension on puller.
One night I was in my shop and...BANG...
Out of nowhere the flywheel just popped off all by itself.
I was nowhere near it at the time. Weird stuff.
