G'day Frank,
the moss catalog shows one pushrod for 948/1098 and another for 1275
it shows one lifter for all.
Do you know if the block / head have been milled much? this will make the
pushrods longer than needed.
>From a look at Vizard, (3rd ed, chapter 11) you have a couple of options...
you could:
a) use the longer pushrods and put some packing strips under the rocker
pillars ( the lock tabs from #2 pillars can be used but you will need 4, which
if anyone has 4 of I have no doubt it will be you).
Be sure that you dont block the oilway. and watch that the rocker dosen't foul
the valve springs.
b)use the shorter pushrods and get longer adjusting screws...which will have
the downside of reducing the rocker ratio due to increasing the lever length.
Also I have always been told never to mix'n'match cams/lifters, but always use
new or resurfaced lifters to lessen the risk of them collapsing, even if they
were only a few hours old.

Ok, so I assembled a 1275 out of all kinds of parts from buckets of internal
engine parts and coffee cans of push rods.
I did notice I had 2 different length push rods, about 3/8" or so different.
SO I use the longer ones in the 1275, they seem to be too long, no adjustment
left and all the valves are open.
Well DUHHH! So I remove the rocker assembly and switch to the shorter push
rods, now I do not have enough thread to adjust the valves correctly.
Was there 3 different sizes? 948, 1098, and 1275?
Are the rocker assemblys different from 948, 1098, 1275?
Or could the lifters be different sizes?
Like I said, I have spackle buckets full of engine guts from who knows what.
Suppose I used 1098 lifters, 948 push rods, and a 1275 rocker assembly,
What is the easiest way to fix it without pulling the head to replace lifters
I don't think I have?
This is for the Ladybug and my daughter is anxious to hear it run and drive
down the street.
She already registered the car before the engine went in, there are no fluids
in it yet and today I managed to put a fuel system in it, rear axle assembly,
rear brakes, exhaust system, alternator set up, carbs, dizzy, and I bought the
fluids.
I am just about burned out on this project but I would like to see it run
too.
I really didn't need this *you can not set the valves because you screwed up
big time this time* with my daughter sitting in the car making vroom vroom
noises.
