Ok so not fuel, pump pressure is steady at 3.5 bar and holds pressure for a good while 15 mins
To check for a vacum leak can i use a gauge and a temp bung ? I have a vacumn gaugewhere would i check from ?
Would a leak only show at high revs ? It ticks over nicely for hours with no problems drive it a mile and a half missfire !
New air filter and spark plugs also added
