this is for a friend and we are stumped.... won't start now...

before it would shut off sometimes when put into reverse like u turned the key off... put it into neu or forword and it will go.. [ this was very intermitant ] ... now no go.... does anyone have any info on these old ones...

 

[imdoo'n]

sounds like the reverse limiter is pooched, pull the black wire on limiter, small square box on clutch side of radiator. it should start unless you have other problems. loose nut behind wrench!!!!:d. you owe me beer.

 

[Garryese]

imdoo is right; those rev limiters were a problem

 

[tex78]

ya but it don't even start at all now

 

[Garryese]

Have you unplugged the rev limiter; it will short out the ignition system and create a no start condition.

 

[tex78]

no we haven't .... wheres it at?

 

[imdoo'n]

small 2.5 in sq, i/2 in thick, black box with 5-6 wires in front of rad, top right corner.

That's the rectifier in front of the rad...the rev limiter is just to the left behind the oil tank.

I'm working on one of these for a buddy and I'm wondering if anyone would know why the coolant isn't circulating properly? We've bled and bled air out of the system, but the temp light is still coming on and the return hose at the bottom of the engine is no where near as warm as the top hose.

Any help would be appreciated.

bad impeller?

Pump impeller or t'stat. If you cannot get all the air out while its running or if it has been severly overheated check for a leaking head gasket
