help - only running 2 cylinders.
recently removed motor and replaced gaskets, cleaned and painted motor etc, removed both heads, didnt split crank case. when i put it back in it, it
seems to only be running on 2 cylinders, and theres an extreme lack of power, electrically all is well brand new leads and plugs, which are all
sparking well. i readjusted valves and timing, so theres no problem there.
and no valves seemed damaged, will do a compression test tommoro just incase.
could the jets be blocked maybe? i didnt mess around with carb at all, just took it off it sat around for a while then put it back.
motor is 1600 single carb on a 72' bus, any ideas??

Double check you firing order.
1432
Also check that the intake manifold is sitting flat on the head.
If it leaks air it will do as you describe.
If your firing order was off, also check the tappets again.

Hmm.. unusual. I once had this trouble with one side.
But u said ur valves were good. I think i had sticky valves, (i neva got around to fix it as it loosened up when i left the throttle on for a while...
only would happen if it sat and did not run for a couple weeks. Only one side would fire, then there would be a sputter from teh other side and then
it would eventually fully loosten up).
The compression test will be interesting. Keep us informed.

check the dizzy cap sometimes you can crack them when taking the motor out if there is a crack between the same side cylinders no fire try another
cap, start with the easy things first
but it does sound like fireing order

compression on cylinders 1 and 2 (the dodgy ones) were about 130 psi which im pretty sure is fine isnt it?
going to try pull the manifold off now, will check the dizzy cap first.
weird thing i noticed was the little notch on the dissy which is supposed to line up with firing position 1 is on the other side. but i made sure i
timed it to this arrangement as thats how it was when i bought it

the reason i asked about the dizzy being removed is that the drive moves and can drop out or move out than drop back in the wrong place a reset would
be inorder i think

try this first reset your leads by using no 3 as no 1 and go anti clockwise 234 give that a go if still no joy as said take it to a good mechanic
may the force be with you

With the engine on # 1 firing, check that it's opposite cylinder [# 3] has its valves on the rock. This means that as you move the crank a small way
back and forth, watch the valves, they BOTH should move, one opening as the other closes. This method will always proove you are on that cylinder's
firing point, ie; #4 firing, #2 valves rocking.

I've been here a few times. With the utmost respect to Matberry, u may find this method a bit easier to follow!
1. Remove both rocker covers.
2. Crank the engine by hand
3. The cycle is: suck (the inlet valve will be open) compress & fire ( both vales will be shut) then blow (the exhaust valve will be open). Do
that for each of the cylinders starting with no. 1. When the inlet valve has JUST closed,(check by jiggling the rocker) the distributor rotor should
be pointing at that cylinder. If it's not fix it. Firing order is 1, 4 3 2
4. Sounds like u r 180 degrees out

Guys,
Cant you you put it on top dead centre on number one (ie inlet and exhaust rockers on no 3 are on the rock) and check the dizzy lines up with no1?
