It's...Alive! But...
Posted by: PequotMonza64 ()

This is one of those shoot from the hip posts where I have a problem but I haven't really thought it through yet. To some, I apologize. To others, here's your chance to spare my brain and look really smart.

So...I got my 1964 110 hp Monza engine back together last night except for the air cleaners. Cranked fine but would not start. Been busy with granddaughters today, but did realize that I had the power wire to the coil on the negative post instead of the positive post.

Eureka! Spark and engine is running pretty decently just from a turn of the key.

Problems:

Right hand carb is spewing gasoline out of hole near the rim at the top of the carb. I'm assuming this means that floats are not stopping the flow when the bowl is full. Feel free to speculate and advise because I'm partially brain dead today.

Also, the choke mechanism on the left had carb is hanging up for some reason, BUT I did break the tiny metal arm coming up from the thermostat area and have not installed the replacement part I got.

So, I'm kind of at Stage Zero where gratefully the engine is running. All the settings are bench settings based on Bob Helt's book. Must be pretty good settings because I was pretty careful during the rebuild process. Just a little hiccup here.

After this, I'll get into the fine tuning and balancing, set the idle, verify the timing. All that stuff.

For the carb dumping fuel, there may be a piece of dirt in the needle/seat assembly or your float is way out of adjustment or full of gas (leaking). Assemble choke and recheck.

Well, there ain't no dirt in there, and the float levels are right, but I think something got messed up when I put the top half of the carb back on. I'll pull it off and see if I can see anything. Check the needle and seat.

Thanks, Colorsarge. Two granddaughters staying over tonight, so maybe tomorrow afternoon.

Sometimes tapping the carburetor with a hammer will free up a sticking float/needle and seat.
Too much fuel pressure can overwhelm the system.

First thing I tried, Jim! ;-)

I think I may have not installed the jet properly, but that doesn't explain why the other carb is working. I'll take the tops off of the carbs later this afternoon and check my work. Then I'll report back.

Right carb had a mismatched inlet valve needle and seat. The seat that came with the carb kit didn't thread in easily, so I had decided to use the original seat. I somehow got the needle from one set in the valve body of a different set, so it was loose and just flopping around.

Replaced it with the needle I had taken out (which was Viton and looked fine), reassembled, and the problem was solved.

The other carb is working fine, but I may pull the top off and just check it.

Also, there seems to be just the slightest leak where the fuel line connects, and I think I might just replace that line rather than fuss with it.

As bench set according to Helt's book, car started right up and ran. I have a tool for synching the carbs, and the left carb is drawing MUCH more than the right. So, next step is synching the carbs and adjusting the idle speed.

Go to page 2 and you will find a post on
Brake line copper flare washers. You can get these in the correct size for your fuel line connection at the carburetor. Cost is minimal and you won’t have to replace a fuel line. Amazon has them.

Thanks for the suggestion. If I can source some locally, I might try it.

In the usual unexplainable manner of Amazon pricing, the Parker Hannifin 2GF-4 come in two ways:

1 (one) for $15.61

or

10 (ten) for $14.82

I know Amazon isn't the best place to get everything in the world.

I'm going to check it out today and see if it's still leaking before doing anything else. I think I might have stopped it last night, but it needs to run awhile to tell.
