fuel distributor diagnosis
microbus difficult to start when cold.
drives fine when warm.
difficult to start again after standing for a while.
no problem with spark or timing.
if it has a fuel distributor it prolly has cis. hard cold starting is usually a symptom of the warm up regulator either clogged or out of ajustment it is not easy to ajust correctly without guages. hard hot start usually is caused by a leaking one way valve at the fuel pump. easy to fix and cheap to buy at the dealership
How can i test the warm up valve whether it needs fixing or not?
