Normally in the order of 2 to 5 degrees at the coldest part of the day (which is usually early morning), but it can get to zero on occasion. That'd be "brass monkey" weather for us, but for you it'd probably be a summer holiday :) -- Regards, Noddy.

On most lpg setups like yours, when the ignition is switched on, the lpg module will turn on the lpg flow for a second or two. Then it won't restart the flow until the motor is running and a signal from the coil above a set frequency is obtained. On some applications, this initial priming isn't enough, and making your own press button switch to over-ride it, and be able to prime for a second longer (or however long you need) can be used in addition to that automatic 2 second burst. that can sometimes help a cold start tremendously. Other than that the 'usual' technique for this kind of setup is to depress the accelerator pedal approximately 2cm, and hold in that position as the key is turned to start it. -- John McKenzie tosspam(a)aol.com abuse(a)yahoo.com abuse(a)hotmail.com abuse(a)earthlink.com abuse(a)aol.com vice.president(a)whitehouse.gov president(a)whitehouse.gov sweep.day(a)accc.gov.au uce(a)ftc.gov admin(a)loopback abuse(a)iprimus.com.au $LOGIN(a)localhost world's #1 sardine whisperer root(a)mailloop.com $USER@$HOST $LOGNAME(a)localhost -h1024(a)localhost abuse(a)msn.com abuse(a)federalpolice.gov.au fraudinfo(a)psinet.com abuse(a)asio.gov.au $USER(a)localhost abuse(a)sprint.com abuse(a)fbi.gov abuse(a)cia.gov

I made this button a year or so ago. But I thought that it's a normal lpg flow, as when engine is at idle not a "burst". So the right technique for cold lpg start is slightly (not to the floor) depressed accelerator pedal. What about warm (hot) starts? -- ___ ____ /__/ / \ ** Registrovani korisnik Linuksa #291606 ** / / \/ /\ \ ** Registered Linux user #291606 ** /__/\____/--\__\ ** http://counter.li.org/ **

That's right - I was trying to choose the words to describe it - as it's probably different place to place what words would be used! > So the right technique for cold lpg start is slightly (not to the floor) > depressed accelerator pedal. What about warm (hot) starts? generally use the same technique, but if it doesn't start, switching the lpg/petrol selector off and foot to the floor it'll fire, and the instant it does, switch the lpg back on. -- John McKenzie tosspam(a)aol.com abuse(a)yahoo.com abuse(a)hotmail.com abuse(a)earthlink.com abuse(a)aol.com vice.president(a)whitehouse.gov president(a)whitehouse.gov sweep.day(a)accc.gov.au uce(a)ftc.gov admin(a)loopback abuse(a)iprimus.com.au $LOGIN(a)localhost world's #1 sardine whisperer root(a)mailloop.com $USER@$HOST $LOGNAME(a)localhost -h1024(a)localhost abuse(a)msn.com abuse(a)federalpolice.gov.au fraudinfo(a)psinet.com abuse(a)asio.gov.au $USER(a)localhost abuse(a)sprint.com abuse(a)fbi.gov abuse(a)cia.gov |
