G'day Oz.
Threre were only two petrol engines widely used in the 135,s one was the continental z134 on the standard 135 ( No dash gauges) and the other engine was the z145 used in the deluxe model it had oil pressure ,ampmeter and tractormeter gauges plus a few other little things.
set points to 12 Thou ,bring number one cylinder to TDC then turn the engine back approx 3/4 inch on the outside edge of the front pulley this will give you 10 Degrees before top dead centre some tractors in australia had a timing "Notch" on the inside edge of the pulley( Nearest the engine) I have never seen a timing window on a petrol engine in australia.
I would replace the points and the condenser, Set the crankshaft as suggested ,with the cap of, loosen the distributor turn the ignition key to the ON and slowly rotate the distributor you will see and hear the spark indicating that the points are indeed at the critical open position ,you can do this as many times as you want just make sure you are not to near the coil or the cap ,you may get a little reminder.
The Hole on the bottom of the intake should have a sintered plug to allow any excess fuel to escape it will not affect the running but it will allow dust to enter the engine sugges you plug with silicone or your favourite hole filler!!
The most common cause of backfire with regard to the carburetor is the butterfly shaft it wears with age and can cause a weak or varying fuel mixture ,there is a service kit available it comes with two bushes and instructions ,you will have to drill out the carburetor body and fit the bushes and new shaft etc, this you will find the tractor runs like the proverbial Swiss Watch .
Note The year of Manufacture is stamped on an oval aluminium tag riveted to the distributor should be say 4/65 meaning 4 th month 1965 or whatever. over the years I have found that although this is a Lucas number the tractors were within a few months of the date stamped on the distributor.
