Yea, I’m thinking fuel delivery too. The carburetor even though it looked rebuilt may not be functioning properly, or not enough engine vacuum To draw the fuel up

Re: Timing issues, Bosch magneto/ laurel cylinder head
 

Is it running any type of exhaust system? Sure sounds like a plugged up exhaust
Have always had trouble starting my hand cranked tractors after a rebuild
Alot of friction and no ring seal

Re: Timing issues, Bosch magneto/ laurel cylinder head
 

Exhaust pipe is only about a foot and a half long. He also tried pulling it around the yard in gear, not even a pop.

Sorry to hear no luck
Just have to go with the basics
Spark,compression,carburetion

Re: Timing issues, Bosch magneto/ laurel cylinder head
 

If it has compression at all, it will draw a fuel mixture as long as the carb is functioning as it should. I have some familiarity with the Miller model S, model SR, and the Master carb for the model T but I can't find anything on a model H carb. Miller & Adamson made a lot of different things back in the day. Holley made a model H-1 carb but I just can't find a Miller model "H".

I think he has some info on the carb, I’ll try and post it when I get back over to see him.

Re: Timing issues, Bosch magneto/ laurel cylinder head
 

Have you checked to see if the plugs are firing in the correct 1,2,4,3 order and that #1 is firing at TDC on the compression stroke?
How is he getting the fuel from the tank to the carb?
Has he tried priming the cylinders by pulling the plugs and adding a bit fuel?
Maybe I missed it, what about compression readings?
Does he have a different carb that he could try?

Re: Timing issues, Bosch magneto/ laurel cylinder head
 

Plugs were placed in a flat steel plate Which was in bolt to the cylinder head all four plugs placed in there and the engine was turned over. Firing order is correct and all plugs were firing

Re: Timing issues, Bosch magneto/ laurel cylinder head
 

But is it on the correct stroke?

Re: Timing issues, Bosch magneto/ laurel cylinder head
 

Thinking so, but I have not gone back to my friends to look recently. He has many projects and I think he put it on the back burner. I’ll stop by there today or tomorrow and see where he’s at with it.
