That solves part of it. Do you think it would work if you switched #2 and #4 wire at the distributor? Or is the Cam and Crankshaft configured differently to give it the even and odd fire?

What you have in odd fire is a inline 4 crank shaft in a V 4. So when it fires 1 then 3 on left bank and moves over to right bank # 4 you have an extra 90 crank shaft degrees or 270 degrees total since # 3 fired. #2 fires in 180 degrees but when going back to fire # 1 you only have 90 degrees. The cam would have to ground to reflect the odd fire configuration. Now if you could get a full speed distributor to work would take some drawing of diagrams and thinking for me.

Sounds way over my head. It would be a lot easier on my head just to run what works.

I am thinking now that if the VG4 is even fire the VH4 distributor will work on it. The piece the distributor bolts into would have to have the same gear as the other engine and the idler gear would have to be the same also. That even confused me.If the idler gear turned the same distance per revolution I would say the housing or generator that the distributor fits into would work on either engine. If I am wrong let me know. I have been wrong before.

This might help, not certain if all VG4 were even fire. All I ever worked on Were VE4,VF4 VH4. If you have a distributor drive it should be 1/2 speed . I revolution of rotor for 2 revolutions of crankshaft. WI magneto’s were most or all full speed. One revolution of MAG for 1 revolution of crankshaft.

I read your smokstak thread and am still confused, except for the part where it says you can not interchange a half speed distributor with a full speed distributor. I would think if you changed what ever is in between the distributor and the idler gear at the same time the distributor would work????

I am trying to modernize a 1965 vintage VG4 to electric start. The parts I am planning on using are coming off an older VG4. The older VG4 has the 3 inch round holes in the sheet metal at the back of the engine so you can clean out schaf from around the cylinders. That is why I think it is older.
