Well went through and cleaned electrical connections, replaced some vac hoses and disassembled and cleaned the Dawes valve.
Nothing made a difference until I cleaned the Dawes valve.
I marked the Dawes valve before disassembly, but when I put it back together I put it back to where I reckon it was, but it's now boosting it's brains out. I keep blowing pipes off. I'm getting up to 22psi at about 1/3 throttle on the flat.
When I put the Dawes back together, I put the ball in the small half and the spring in the large half which I'm pretty sure is correct.
I'm winding the two halves apart to lower the boost. Is that correct???
I can't remember the procedure for setting the boost. From memory it's something like go up a hill (or put the vehicle under load) at about 3000 rpm until you get a boost of 15-16 psi. Is that correct??
Thanks for any help.
