Sorry for taking so long to post this, but we had a little rain in my area, Hurricane Harvey. We only had very minimal damage, but not from flooding, just the wind and rain. I have driven the truck with the new motor and all appears well. The only issue I have is with the carburetor. I believe it either has a slow leak or for some reason the gas is being siphoned when the motor is not started every day. The bowl will be empty if I do not start the truck every day. I am going to remove it and check for a leak. If there is one, I will replace it.
For anyone that did not read my original post about the engine here it is.
Just wanted to let those interested I have started the new engine after resolving the no spark issue. I also would like to share some information regarding the new engine. I purchased the engine from AutoZone. Normally I would have built it myself, but it was less expensive to purchase one. The engine for the truck was $1232.00, but I had a $150.00 coupon from AutoZone. When I ordered the engine I also received a $150.00 rebate. So the engine cost $932.00. It comes with a 3 year warranty. The engine was built by Surefire.

At start up the engine oil pressure was in the middle of the oil pressure gauge, around the "m" on normal. The temperature was normal.

The engine was sold as a long block, with a new oil pump. I purchased a new water pump and radiator.

The point of this post is to let those interested in the engine know I will post updates as time goes by.

Also thanks again for the help with the no spark issue.

Thanks,
Mitchell

 

Mitchell,

The gas in the bowl may be evaporating; the original installation should have had a charcoal canister to collect vapors and feed them back to the combustion chambers.

You also might want to install a wooden or poly spacer between the carb & manifold, something that doesn't transfer heat.

 

Yes, I have had the same problem when I took the large fat hose that plugs into the top of the carb off, and left that big port on top of the carb open. It lets the fuel evaporate from the bowl a lot faster than normal.

You can try plugging that port and see if it helps. If you have trouble starting it on a hot day, you may have to come up with something else. Some people have a hot starting problem when that hose is plugged, some don't.

 

Thanks, I I will let you know if that solves the problem in a few days.

 

I waited a few days after plugging the port then started the truck. It appears to start faster. I waited a couple of days after that and it started quicker. It did not spin and pump fuel into the carb so it would start. I started it Saturday and will wait until Tuesday to start it again. Hopefully this resolves my issue.

Thanks for the suggestion,
Mitchell

 

I did not start the truck for a few days. When I did start the motor it took a couple of tries to start. Apparently fuel is still evaporating or leaking. It does star better with the vent plugged, but I think there is another issue. If I start it everyday, it fires right up. I hope to pull the carb off soon and inspect it for leaks.

 

Are you pumping the pedal a few times before you try to crank it? That should help it if there is still a little bit of fuel in the bowl.

 

Yes, I depress the pedal to allow the choke to set, then one or two more times. The longer the truck is not started, the more time it takes to start. I know I will remove the carb soon and see if I can find a leak or something else that is creating the problem.
Thanks for the replies,
Mitchell

 

I solved the problem with the carburetor going dry. I know it has been a while since I first posted this, but I got side tracked on another project. Prior to me obtaining the truck someone must have rebuilt the carb. I disassembled the carb and discovered the pump disc ball was missing. This was allowing the gas to weep up through the venturi cluster and evaporate. Now when I do not start the truck for a few days, it will start right up as there is fuel in the bowl.

Thank you for posting back what you found and the fix as i am sure it will help others.
