A GREAT BIG THANKS !!! to each and evry one of you memebers who had a hand in advice along the way. As well as to the folks responsible for this web site "FANTASTIC IDEA" and all the right folks make use of the place. DAMN!! I'm Happy! I can can say D*MN right ?

 

Great job. Good to see another one come together and run!!

 

Congrats on your project, this old computer lost its sound so i'll have to run it on the newer one.
Picture looks like your vacuum advance hose isn't connected to the dizzy, important item.

 

I was setting the timing, 8º seems to be best, vac line taped off, in gear 750-800rpm. Although I noticed the vac line from the carb has vac all the time ? I thought at idle it was supposed to be no vac ?? I'm sure there is some dialing in to do..gonna head over to Harbor Freight for a vac gauge today and see what I can dial in..

 

You should be running ported vacuum (not to start Ported vs Manifold pissing war). Best to run a vacuum gauge in the cab while driving to know what the dizzy is getting, helps with you dialing it in.

 

Isn't the tube coming off the side of the carb the ported one? vs the fitting on the intake behind the carb..

 

Nice!

If that really is the "ported vacuum" port where you have vacuum at idle, here's the thing:

There's a little hole in each primary venturi, that's just above the throttle plates. As the plates open, that hole is uncovered, and the air flowing past it produces vacuum.

If you're getting vacuum there at idle, you have the throttle plates too far open - either the idle is too high, or you don't have enough advance requiring the plates be opened further to idle.

What cam is in it?

8 degrees might not be enough ...

 

http://fastengineparts.com/products_view.php?id=1539 this is the RV cam that came with the rebuild kit. (I know Rusty) ...but it's in there, we'll see if that will change down the road.

So if the idle at 750rpm in gear with the vac line off and plugged... is pulling a vac off the tube in front of the choke assembly.. I should be able to move the dizzy around and find a spot where the vac subsides ?

 

You have to back off the throttle stop screw to make the vacuum go away. I think 750 is to fast and causing you problem, 600 to 650 is more like it.

 

I'll try to get it dialed in this weekend. I put it on a vac gauge last night and the needle was riding 19.5 - 20.5 with a very slow easy flux between those numbers. We'll see how much improvement can be made over the weekend.

 

Cranked her up at lunch time and let her warm up then idled down to almost a stutter with vac still on the line..?? I'll look closer at everything later..maybe the port on the carb is not ported ? puzzling..

 

What the hell? I decided to give the 4bbl a shot as the 2bbl seemed to be in order more or less.. 1st the filter fitting leaked gas all over... my fault. Then I get it to fire after about 20 attempts.."You cannot plug off the vent tubes" it wont run!! I learned something on my own for once!!.. So it fires and shoots to 5k 6k ? I **** my self even though the hand was on the ignition.. Sounded Awsome..neighbor might not agree...So the linkage has issues, springs seems to week to handle return, idling below 1500 is just near impossible..If it wernt for the fact the engine sounded like it could rip a freekin house down.. I'd give up now...

Mostly the hiss from the carb airflow is just ungodly..???? Ideas.. is this normal..??

 

Put the beer down, take a deep breath, and re-think things

I don't understand, is the throttle linkage binding and the motor is revving out to heck?

What's changed?
