Hi all,

I have an 86 Holdsworth camper with a DG engine. It sat on my drive for several months without being run but was working fine when I bought it at the end of last year. Its been running erratically, stalling and very lumpy at idle ( pierburg carb ) ever since I fired it up a couple of months ago.

Stuff that I've done.

New exhaust.
New fuel pump.
Fixed leaks in fuel tank ( three way connector on top of tank was in two pieces ).
New fuel filter.
Replaced all fuel lines and breather pipes ( all pretty rotten ).
New HT leads and plugs.
New air filter.
New vacuum hoses.
Checked coil resistance ( within the range specified in haynes ).
Good compression on all cylinders.

errr.. might have done some other things that I've forgotten

Haven't checked timing ( no timing light ) but it was running fine before it got laid up for a few months and I haven't touched the distributer other than to check the cap and rotor arm which look ok.

Would all this ( sorry for the long post ) suggest the carb needs reconditioning?

Today I was refilling the coolant system after repairing some leaks and when revving the engine at the carb and releasing the throttle the revs dropped suddenly and I could hear a loud whistling noise before it conked out. Air leak?

I'm quite new to all this stuff so any help gratefully received.

Back to welding the dreaded offside sill

try replacing the rotor arm , esp if it's a rev limited one , made a fair difference to my 1986 DG.

Ok I'll look into a replacement rotor arm.

Any thoughts on the whistling noise?

Thanks

Jim

I once had a collapsed exhaust silencer do that (internally rotted and the sound deadening material had blocked the exit for the fumes) mind you...it hissed all the time.

Just to update.... the choke vacuum pull down unit is shot on my Pierburg carb, I'm wondering
if the diaphragm in the pull down is letting air into carb and upsetting the system. Does this make sense or am I talking a load of.....
