Question: The ignition "boost" is disconnected, any reason to connect it?

If the diaphragm passes the suck test, go ahead and hook it up...it sure will keep your plugs clean.

Thank you - I'll give it a test.

Much appreciated!

Good catch - The retaining spring was missing from the float valve. I pulled one off the old carbs, cleaned it up and installed it.

I'm impressed!

This fits the bill and is the one I used on my '89.

Facet - FPF-40178N   12V, 2-3.5PSI


Many thanks!

Did you go with the stock location?

Final version, I'm not going to do it, I'd have to order 10 sets and resale would be close to $100.00 a set with shipping.

If I'm going with a simple block, I'll do it myself......

Steve i knew a good mechanic like you had full control ! :drinks:

Still working on the fuel pump placement.
It's close, but just not right.......
Facet calls for a 72 micron filter, I'll probably going with more filtration. I have a 12 micron inline, but sure don't want to restrict flow to the pump.

Made some progress today.

Petcock was nasty. Was able to carefully disassemble it, clean it and reassemble. Seems to be working. The filter, I pulled it out. I may replace the petcock all together as there is an inline filter before the pump, and an inline shut off.

Took a test ride, eff'ing valve cover gasket popped and sprayed oil all over my bare leg.

Test ride, shorts, sandals, tee shirt, no helmet, no sunglasses, it was sort of one of those moments I questioned my judgement.

I got over it.

Very good Steve, how is the fuel pump controller working out?

Thanks - it seems to work as it should.

I was pleased to find the tach/coil connection could be done near the ignition control box. I soldered the wire in place, will probably do the same to another I used a connector on. All of the connections were pretty straight forward.

I'm surprised how quiet the fuel pump is. I just hope it flows enough at speed.

I did connect the vaccum line to the ignition box - I've not looked to see what it does to the ignition curve - If it's just for emissions, I'll disconnect it.

Any preference?

"If" the diaphragm passes the suck test....no preference.

That extra 10* of advance when the throttle plates close, sure cleans off the plugs.

Good humor Steve what really made me LOL was the picture of the petcock filter i guess you can say that is well used .

Steve,

Just gotta ask, why would that happen?  All pistons leak combustion gasses to some extent. 
Is there no crankcase ventilation that works, with that engine?  Never heard of this malfunction before.
Seems to me, if the valve cover gasket did not blow out, then some other seals or gaskets would soon blow out instead.
Cheers,
Red

P.S. Life is too short, and health is too valuable, to ride on cheap parade-duty tires.

I've had them blow out on cars and bikes.

I'm not sure why on this instance, as it's got a very free flowing filter on the vent.

I chalk it up to "shit happens" and that I probably didn't install the gasket properly (which really pisses me off because I spent a lot of time making sure the damn thing was perfect).

In the past it usually was due to either an obstruction in the crankcase ventilation system (as you mentioned) or a really big ka-pow from the deep dark depths.....
