James, A 32/36 is not usually affected by swirling if the bypass hoses are fitted i.e. I've run them in Canberra and you don't need hot air intakes with them. They are however prone to blocking the air bleeds especially in dusty climates if the air cleaner element is not cleaned/replaced at the recommended intervals. To clear the bleeds on the car you just shove your hand over the venturis with the engine running at around 2K rpm and at the same time open the throttle wide. The suck of the engine will clear the bleeds and usually stall the engine in the process due to flooding. Sometimes you need to repeat the process the few times.
A L engine that has steel valve seats is quite OK to run on unleaded fuel. That covers most L's made after ~74 and some ppl say the Aussie Series 2 Bluebird engine is not suitable but we've been told otherwise as well. Depending on compression ratio you'll need 96 or 98 Octane but if it doesn't detonate on LRP and Premium ULP will be OK. Now, the controversial bit as it's my personal opinion based upon the characteristics of my engine with a CR of over 10.5:1 - my preferences are in this order : Mobil Synergy, Shell Optimax, BP Ultimate and then (PULP's) - Ampol/Caltex Vortex and then any of the others and then if I'm really stuck in the bush a splash and go of LRP to get me to the next major centre. regards Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of james wade Sent: Friday, 12 July 2002 9:43 AM To: [EMAIL PROTECTED] Subject: RE: water probs I have a 32/36 downdraught webber. Yes, i'm using LRP - should i use regular unleaded or premium? Wont that muddle up the engine? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Terry Rudd Sent: Friday, 12 July 2002 11:43 PM To: [EMAIL PROTECTED] Subject: RE: water probs James, What sort of carbie have you got - it sounds to me like it's got a flat spot or maybe blocked air bleeds. Another thing that Hitachi downdrafts don't like is the manifold bypass hoses blocked off. The warmth in the manifold from the water circulating in winter stops the fuel/air mixture from separating back to liquid droplets (there's a name for this that I've forgotten) but basically when the mixture turns the corner is swirls if the air temp is very cold. You may have seen hot air intakes on the likes of Stanza and 200B/Bluebird that suck warm air from the exhaust manifold. Some L engines were very prone to this condition when driven in very cold climates, these warm air intake systems are a nuisance in summer though. Another thought, what fuel are you using? as LRP winter formula is total crap and I wouldn't put it in a lawn mower unless I was desperate. regards terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of james wade Sent: Thursday, 11 July 2002 11:43 PM To: [EMAIL PROTECTED] Subject: RE: water probs --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ ---------------------------------------------------------------------
