Not so hard if the engine is on the bench. if it is in the truck might be a bit tougher. There are a few pics in my thread, but here is one. Your engine might have 2 springs. The one pictured is still the one you need to change. I hooked it onto the speed control arm first, and had a piece of dental floss on the other end. Fished the string through the shut down lever hole, put the speed control arm plate back on, then pull the string to get the spring to come aft, then hook it with a pick, lever it back some more until you can grab it with some needle nose pliers, then work the spring hook onto the governor arm

 

did you shorten the spring or use a different one?

 

both. I don't remember where I posted the details about my spring. It was not on my buid. But I did post up the details. I do remember a bit of the details though. The stock spring is 2.0" hook to hook and about .050" wire dia. I got a longer spring with I think .057 wire, and cut it and bent a new eye in it to get the 2" I ended up with 3150 rpm on my first and only test. The spring I want is 2" long .5" dia. and .067-.077 dia wire. That spring is available, but the 2 spring shops I found it, had $40 and $70 minimum order, and the spring is about $3 for one.
ok back out to the shop, I hope to have my engine sitting on the mounts tonight.

have fun

 

I just found a spring on mcmaster that's 1.875" long, .531 OD, with .080 dia wire, and an extended length of 2.085". It appears to be pretty hefty. Do you think that would work? It comes in a pack of 6 for $10.17 plus shipping. I'd be willing to buy it then send out the extras to everyone else if you think it would work.

 

i am new to the whole changing springs thing but that sounds a little big

 

The only thing to really be careful about is the length. It can't be any shorter than the stock one because it won't go to idle. With the stock spring, it is stretched some at idle, so the stiffer one may not be stretched at all at low rpm so it may not return to idle. With mine it almost didn't have enough length to idle and it is the same length as stock but real stiff. I don't have the exact dimensions, it was a long time ago. So I would suggest a bit longer to compensate. Oh, and mine will spin to 3800 rpm.

 

how far exactly did your machine the bellhousing to? and how think is your adapter plate

 

i did the flywheel first so i knew how thick the bellhousing needed to be and my plate is 3/8 thick

 

i have been driving the truck for about two weeks i have the rpm up to 2900 i had a couple leaks but now i can see what kind of mileage i am getting my idle is about 1000 witch seems hight to me what rpm are all you yours idling at?

 

700 or so, 1000 is too high.
