OK. I have not changed this filter since it was new nine years and 120,000 km ago. I have never found more than a pinch of crud in them ever in nearly thirty years. Only found this stuff when I shook the lock off as I rekitted my Impco J That dark fur ball in front of the element is the small magnet!!

yeah, here we go. This is my post from some time ago when I ran a 100 mixer and got results above. Now, more recently I tried the 100 on similar engine, same capacity just better breathing and could hardly start or run it, so I upped it to the 200 off the L converter and even though mixtures are gre...

Hmmm.....maybe two 100 HP rated J or Cobra converters to feed the perfectly sized in air CFM 200 mixer? Thinking my lean bogs could be dealt with by the Peel Instruments CP401 nicely. I must apologise if my tinkering confuses people as I am playing with a non turbo version of engine partly in prep f...

Thanks for explaining stuff C3 I have also run 100 and 125 off an L converter but this time whatever was up don't know. The 200 resolved everything at that point. I am mucking about in prep for turbo application. With turbo in mind, 1800 cc boosted to 12 psi and rev to 6500 its cfm comes almost exac...

Gosh, they have looked in here almost daily in years gone. Took me months to pull a finger out and go for a diagnostic rune with tailpipe analyzer .....now I am running an L converter I rebuilt years ago and it sat idle for a long time before working nicely with a 125 on different engine in same ute...

Hmmm....looks like Franz and C3 have become casual visitors here,or got nothing to say

Franz is likely to be nodding his head thinking I am silly as a J and 125 is at the sweet spot of an 1800cc four...but am in learn prep mode for turbo and prefer learn on something free of a propane fed turbine !!

This little beast of 1791cc will see 12 or 13 psi boost up to about 6500 - 7000 rpm

Well, I ran a 125 off the L converter on similar engine- flat four, 1791cc but it was a single port head and intake. This is twin port head and intake and did not like it so swapped the 200 in and (swear word) does it go now! Bogs down a little if I don't drive it to suit. Now have great induction r...

I have seen twin mixer set ups on big vee 8 s but never looked and remembered the detail so question is ...can I run a pair of 100 impco mixers off one L converter. Intended to be feeding same plenum not one per bank.

Any comments welcome

Yeah, the copy I had said the second part rotated the air horn 90 degrees and I figure the air horn is on the intake side. Maybe the air horn is also on the outlet. Pre internet listings! I have some e-copies somewhere of late 70's early 80's Impco sheets.

it is AS3-10
Impco cat could use a better description

Great work gents!. Thanks heaps, now we are half way there, coz I can see two adaptors, and if you squint you can see the join between the two, the second is rather thin and simply allows mixer to rotate 90 degrees. I think that part number is listed a little further down on that link above me ^^^ ...

Well, for starters here is an ebay link to a 100 mixer to suit Mitsu Forks and it has two neat looking adapters on its base https://www.ebay.com/itm/Propane-LPG-Forklift-Caterpiller-Cat-Mitsubishi-Carburetor-Carb-Mixer-4G64-4G63-/182698854064? I'm hoping someone can give me the part numbers to chase...

Oh it works OK but I think it will be more responsive once the lesser volume manifold goes back on. Think I will hold the biggie for a turbo application at some stage. There are no hose clamps easily visible , but there is one on the bell of the mixer air filter side :) The other air connections are...

try this if it works
