So drive my 1600 dual port every week to work . This morning 1st frost . Camper was lumpy and sluggish 1st 10 mins anything I can do to help that ? Sent from my SM-S901B using Tapatalk
10 mins is a long time, there should be enough heat in the heads to run smoothly after less than a minute IMO. If you have choke you should be able to start and drive just fine immediately. But you haven't told us one single thing about your carb(s) or distributor so you're not going to get a useful answer.
If you've got one of these fitted to the carb chuck it in the bin and fit a stock oil bath air filter:
I have solex 34 pic2 and with choke I'm sure I adjusted that the other month as engine wouldn't idle ? Sent from my SM-S901B using Tapatalk
Have 1 of these but bought a original not oil bath tho as mine 75 just never got round fitting it Sent from my SM-S901B using Tapatalk
Also check the heat riser pipes from exhaust to manifold are not blocked with carbon. Some aftermarket exhaust need the heat riser connections drilling out to allow exhaust gases to reach the manifold It sound like your suffering from carburettor icing.
Definitely carb icing ("manifold chilling" would be a better description). Feels like a big flat spot. Get the original air filter with warm air feed back in, and that should cure it. I've found the preheat pipes on the manifold (if they're not bunged up with carbon) don't appear to do much.
They do with an exhaust that copies the original design so it pulls the gasses through. exhausts with both risers just off the connecting pipes don’t work as well
The stock design has one heat riser pipe directly off the exhaust pipe near the head and the other to the actual box like this most aftermarket exhausts have both directly off the exhaust pipe near the head so the exhaust gasses don’t flow Like this
True. I suspect on the aftermarket 4 into 1s, they're not actually intended to be drilled through - just for show. My van originally came with a crap chromy filter and an enormous flat spot. I found just fitting the original airbox, stovepipe etc was enough to cure it.
Ahem !!you should know by now all sub standard parts like this should not be thrown in the bin, They are to be thrown over snottys fence out of harm’s way where they can’t be used again
One of my favourite dub channels on youtube modified their aftermarket exhaust to more closely match the original. I debated doing it to the baja exhaust but it would've been a bit of a faff.
Any idea how I can get it to play on the app on my phone instead of on the forum? That way it will be in the youtube library so I can watch it later.
What I found interesting about that was after the mod so it was more like stock was that he observed lower cylinder head temps on a hotter day than before the mod.
