Bos,
I just uploaded some pics. See what you think.
Can I just leave the thermos in for now???
Yep definitely leave them in, you a getting better restriction with them due to seeing that telltale pressure up more and you havent seen the temperature get into the too hot zone.
I dont know enough about that system to comment on what you could do to bypass a removed control module.
On mine and most others ive worked on the thermostat opens when temperature gets hot at low rpm. When rpm increase the extra water puts more pressure on the system and lifts open poppet valves or pushes the whole thermostat housing back off its seat and water then can gush around it and flood lots of volume through the system.
On yours there looks to meant to be a valve connected to your throttle plate that must change the routing of water there as FBullet says allowing the thermost to lift off. I really dont know why they complicated it with that and didnt just use the spring system other motors have.
Thanks Bos.
Hopefully I can source a control valve. I know it wasn't the previous owner, as he was such a nice old dude. So can't be pissed at him.
ill try it on the water tomorrow.
Sparks look good by the way.
I still dont get the high idle rpm of 900. I wonder if she is still running slightly cold at idle due to the water set up this last owner genius did to it. Perhaps in this current set up its making the thermostats be unseated due to no pressure coming on them from the control line by the impeller. Problem is if you keep them in they wont let enough water in at higher rpm and ive no idea what grade spring would work to keep them seated at idle and rise off as rpm increases.
But im sure theres a way to find out
If she was still running cold from unseated thermos that could explain the knock in your low range too as you powered up while cool
What type of file did you use to upload your pics? ALL I get is error.

Hi Bos,
See idle video attached of startup. It was the best I could give today.
I did notice tell tale dropped alot in pressure today compared to the first run. I think the stats are blocking the head off now, but the temp didnt go up... I think I need to pull them out until I sort the valve out. What do you think think?

Hi Bos,
Mate really appreciate you helping me out. I should also say that the thermos I got were the 0434137 - Thermostat, 140 Degrees model, and not the old style. Would this change anything.
I have read a little in this forum on the Dhadley and what he suggests???
I suspect you need the right ones for that motor and either would require the control valve too.
Post a link to what Dhadley has written if you still want to do what he/she says.
I think you need to find out whats needed for the 3 cylinder conversion and if you go ahead with the control valve you will need to find out where the impeller pressure comes from to plug into the control valve as im surprised if you have done the impeller that you didnt see something down there then. Check out if you order a control valve that it comes with the little metal bit that joins onto the timing plate thing, although you could probably fashion one if necessary.
Chin up, im on my third puncture in three days on gravel roads here and am now out of puncture patches, you will get her running just right soon enough
Hi BOS
Not really sure what you mean by link to timing etc.When I pulled down the kit, I replaced exactly the kit. Didn’t see much other than the normal gear link and drive shaft. Can number what you mean below?
