The fuel is now adjusted so it makes 10 psi max at 5th gear. I should be safe for now without a pyro. It runs much better than on 6 psi

Do you have a link, nope, no pyro yet. But im not going over 10-12psi. For now the boost was max 6psi

As i read in the post above, i have a non fdc "g" pump. That explains a litle more.

Fdc physical removed, how to adjust fuel? With the hex nut in the back of the pump?

What is wheep tab? Its a m621 1968 model. Delivered to the Norwegian army, single wheels, lockers etc. Its not a td block, and the turbosetup is taken from a m35a2. thats why im wondering if this block have a weaker head gasket?

Thanks guys, so 12-14 psi is 100% safe to not get a meltdown, and not a blown headgasket? The headgadket on non turbo are weaker the td blocks ?

Timing is stock non turbo , but thats just fine. When turning up the cumminsengine i have, timing is also advanced. Where is the best place to drill? And do you drill whith engine not running, and use grease or what?

Hello, bought a new deuce today. The last owner converted it to a whistler turbo. It smokes nothing as it is now, and not much more power vs my old cranckedup(heavy blacksmoke) non turbo. I dont have egt gauge yet. But i have a boost gauge in my garage that i propably can install tomorow...

Piston was stuck, and i propably destroyed the button and spring when tappin it. Have not been looking any closer at the old hh

I changed the HH today, now my M621 is running again:) thanks for the info guys

Ok, then i will try to get the hh of tomorow.

Have now screwed that bolt out of the hh. Its a piston down there, should it move or is it a tiny piston in the hole in the middle that should move? It seems like nothing move when cranking even if i tapped it a couple of times. But hard to see, the diesel is flowing out when cranking

Thanks, i have now read true the thread and will unscrew the bolt on the top of the HH tomorrow, maybe mine is stuck also... :(

Oh ****....but have only runned about 100 gal of wmo, could it have messed up the pump already?? Tryed the search function, but coult not find any thread with search on Kennys@wirr.com

It was down a hill so i dont noticed if it sputtered, propably not, think the intank pump works fine, i have bleeded several liters tru the new secondary filters, and also have diesel out of the fdc when intankpump is on. Also thinned the wmo with some gallons diesel/gasoline.and got half tank...
